Why does the cell from the inner lining of the intestine has the folded mebrance?
The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
Folded membranes are an advantage to a cell because?
It gives a cell greater surface area, if they are folded, they are more compact, allowing the cell to do more. /\/\/\/\/\/\/\/\ _______________ Both drawings have 16 segments of the same length. The one above is folded and is able to hold the same in less space, or more in the same space. /\/\/\/\/\/\/\/\ = 16 __________ = 10 (same space, but more area)
What cell is cell lining the small intestine?
the cell lining of the small intestine is called villi and are small, finger-like projections that are used to increase surface area.
How is Epithelial cell in intestinal track?
Epithelial cells cover the surface of the intestine.
What is the advantage of having a folded membrane surrounding the cell or within the cytoplasm or within organelles?
Having folded membranes increases the surface area available for biochemical reactions and cellular processes to occur. This allows for more efficient exchange of materials and communication within the cell. Additionally, it provides a compartmentalized environment that can separate different biochemical processes, optimizing cellular functions.
How are the folded membranes in mitcochondria an advantage?
The folded membranes in mitochondria, called cristae, provide a larger surface area for cellular respiration to occur. This increased surface area allows for more efficient production of ATP, the cell's energy currency. Consequently, the folded membranes enhance the mitochondria's ability to generate energy for the cell.
Mention two structural features of small intestine which add to the absorptive capacity?
Four features of the small intestine make it efficient at absorption of digested food: 1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!
What are folds of the cell membrane on the free surface?
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
How is the Golgi apparatus similar to the large intestines?
The large intestine primarily operates to reduce water concentration in waste. The intestine is somewhat like the Golgi body in that it is folded over numerous times to increase surface area. In the Golgi, this allows for signaling with enzymes and other cellular proteins. In the intestine, it allows for increased access to digestive absorption.
How does the kidney achieve a large surface area?
The cells lining the proximal tubules of the nephrons have a highly folded cell membrane on the lumen side of the tubule made of microvilli. This is referred to as a brush border and is important in increasing the surface area for reabsorption of components of the filtrate as it passes down the nephron.
What is one way that the small intestine is modified to increase the surface area for digestoin and absorption?
The cell surface which lines the intestines have villi and microvilli. These are finger-like protrusions which increase the surface vastly.
What is the definition of cell surface area?
The surface area of a cell is defined as the total area encompassing the perimeter of the outer cell layer. The surface area of a cell is an important part of the Surface Area to Volume Ratio in terms of the effect it has on molecules that are entering or exit the cell.
