Help with essay writingSometimes though, ROS accumulate beyond the capacity of such defenses. Oxidative stress is the term used to describe damage to cellular components caused by ROS. Due to their characteristic unpaired electrons, ROS can set off chain reactions where they remove electrons from other molecules, which then become oxidized and reactive, and do the same to other molecules, causing a chain reaction. ROS can cause permanent damage to cellular lipids, proteins, carbohydrates, and nucleic acids. Damaged DNA can lead to genetic mutations and even cancer. It is noteworthy that these diseases are largely age-related. Many scientists believe that oxidative stress is a major contributor to the aging process. Aging and the… Cell: The Free Radical Theory The free radical theory on aging was originally proposed in the s, and still remains under debate. Generally speaking, the free radical theory of aging suggests that accumulated cellular damage from oxidative stress contributes to the physiological and anatomical effects of aging. There are two significantly different versions of this theory: one states that the aging process itself is a result of oxidative damage, and the other states that oxidative damage causes age-related disease and disorders. The latter version of the theory is more widely accepted than the former. However, many lines of evidence suggest that oxidative damage does contribute to the aging process. Research has shown that reducing oxidative damage can result in a longer lifespan in certain organisms such as yeast, worms, and fruit flies. Conversely, increasing oxidative damage can shorten the lifespan of mice and worms. Interestingly, a manipulation called calorie-restriction moderately restricting the caloric intake has been shown to increase life span in some laboratory animals. It is believed that this increase is at least in part due to a reduction of oxidative stress. However, a long-term study of primates with calorie-restriction showed no increase in their lifespan. A great deal of additional research will be required to better understand the link between reactive oxygen species and aging. The Cytoskeleton Much like the bony skeleton structurally supports the human body, the cytoskeleton helps the cells to maintain their structural integrity. The cytoskeleton is a group of fibrous proteins that provide structural support for cells, but this is only one of the functions of the cytoskeleton. Cytoskeletal components are also critical for cell motility, cell reproduction, and transportation of substances within the cell. The cytoskeleton forms a complex thread-like network throughout the cell consisting of three different kinds of protein-based filaments: microfilaments, intermediate filaments, and microtubules Figure 6. The thickest of the three is the microtubule, a structural filament composed of subunits of a protein called tubulin. Microtubules maintain cell shape and structure, help resist compression of the cell, and play a role in positioning the organelles within the cell. Microtubules also make up two types of cellular appendages important for motion: cilia and flagella. Cilia are found on many cells of the body, including the epithelial cells that line the airways of the respiratory system. Cilia move rhythmically; they beat constantly, moving waste materials such as dust, mucus, and bacteria upward through the airways, away from the lungs and toward the mouth. Beating cilia on cells in the female fallopian tubes move egg cells from the ovary towards the uterus. The only flagellated cell in humans is the sperm cell that must propel itself towards female egg cells. In animal cells, vacuoles are generally small. Vacuoles tend to be large in plant cells and play several roles: storing nutrients and waste products, helping increase cell size during growth, and even acting much like lysosomes of animal cells. The plant cell vacuole also regulates turgor pressure in the cell. Water collects in cell vacuoles, pressing outward against the cell wall and producing rigidity in the plant. Without sufficient water, turgor pressure drops and the plant wilts. In higher plant cells, that polysaccharide is usually cellulose. The cell wall provides and maintains the shape of these cells and serves as a protective barrier. Fluid collects in the plant cell vacuole and pushes out against the cell wall. This turgor pressure is responsible for the crispness of fresh vegetables. These organelles contain the plant cell's chlorophyll responsible for the plant's green color and the ability to absorb energy from sunlight. This energy is used to convert water plus atmospheric carbon dioxide into metabolizable sugars by the biochemical process of photosynthesis. Chloroplasts have a double outer membrane. Within the stroma are other membrane structures - the thylakoids. Estrella Moumtain Community College provides a good source of information on photosynthesis. Smooth Endoplasmic Reticulum: Throughout the eukaryotic cell, especially those responsible for the production of hormones and other secretory products, is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short. The ER is a continuation of the outer nuclear membrane and its varied functions suggest the complexity of the eukaryotic cell. The smooth endoplasmic reticulum is so named because it appears smooth by electron microscopy. Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction. We can think of the system as analogous to a series of switching yards and train tracks, where materials are sorted with respect to their destinations at the switching yards and sent to those destinations along specific tracks in the cytoskeleton. Proteins destined for secretion are made on ribosomes bound to the RER. The proteins move through the endomembrane system and are dispatched from the trans face of the Golgi apparatus in transport vesicles that move through the cytoplasm and then fuse with the plasma membrane releasing the protein to the outside of the cell. Examples of secretory proteins are collagen, insulin, and digestive enzymes of the stomach and intestine. In a similar way, proteins destined for a particular cell organelle move to the organelle in transport vesicles that deposit their contents in the organelle by membrane fusion. Like secretory proteins and some other proteins, proteins destined for lysosomes are made on ribosomes bound to the RER and move through the endomembrane system. In this case the lysosomal protein-containing vesicle that buds from the trans face of the Golgi apparatus is the lysosome itself. The figure below illustrates at a glance the structures that are common to both animal and plant cells, as well as the structures that are unique to each. Structures that are common to both plant and animal cells are labeled between the cells; structures that are unique to plants are labeled on the left of the cells and those unique to animals are labeled on the right. Chloroplasts are plant cell organelles that contain chlorophyll and the enzymes required for photosynthesis, the light-dependent synthesis of carbohydrates from carbon dioxide CO2 and water H2O. Oxygen O2 is a product of the photosynthesis process, and is released into the atmosphere. Chloroplasts are large organelles bounded by a double membrane and containing DNA. Unlike the mitochondrial double membrane, the inner membrane is not folded. Distinctly separate from the double membrane is an internal membrane system consisting of flattened sacs and called thylakoids. The space between the thylakoid and the outer membranes is called the stroma. The stroma contains the chloroplast DNA as well as components of the protein synthesizing machinery specific for the chloroplast, namely the ribosomes, tRNAs, and specific proteins and enzymes. Most of the components of photosynthesis are located in the thylakoids. The thylakoid membranes are organized into stacks called grana. The interior of the thylakoid is the lumen. In humans, they contain the pigment 'melanin' that protects the skin from the ultraviolet rays of the sun. Functions of the Cytoplasm The cytoplasm acts as a medium where various organelles can remain suspended at their proper places with the help of cytoskeletal fibers. Besides giving shape to the cell, the cytoskeleton facilitates the movement of the cell and the different substances found within the cell. The enzymes present in the cytoplasm help breakdown the macromolecules so that they can be used by various organelles. For example, mitochondria cannot use glucose present in the cell, unless it is broken down by the enzymes into pyruvate. The enzymes act as catalysts in glycolysis, as well as in the synthesis of fatty acid, sugar, and amino acid. Several crucial biochemical reactions and cellular activities take place in the cytoplasm. The cytoplasm is the site of vital functions like cell reproduction, protein synthesis, anaerobic glycolysis, and cytokinesis. The various organelles contained in the cytoplasm perform their specific functions, which are crucial for the proper working and survival of the cell. The processes related to the growth, expansion, as well as the division of the cell take place in the cytoplasm. The nutrients are absorbed and stored in the cytoplasm so that these can be used by various organelles when needed. The cytoplasm also helps dissolve the waste products. Paramecium Caudatum In some organisms, the microtubules function as cilia and flagella, and thus, help in the locomotion of the organism. The organelles present in the cytoplasm perform functions that are crucial for the survival of the cell. However, the smooth operation of all these functions depends on the existence of cytoplasm, as it provides the medium for carrying out these vital processes. Share This.
