in a hypertonic solution, water leaves a cell by osmosis, causing the cell to shrink. In the hypotonic solution the concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell. Therefore, there is more water outside the cell than inside.
Answer:
The inactive precursor to the enzyme pepsin that digests proteins in the stomach. (Ans A)
Explanation:
Pepsin is known as a digestive enzyme which is present in humans and other species digestive system. It is produced by the stomach, where it helps to digest the proteins and break down into amino acids which are present in food. In the stomach, a cell is known as a peptic or chief cell that helps to release Pepsinogen.
The Pepsinogen secreted by Chief cells is an inactive form of pepsin, on exposure to HCL (hydrochloric acid secretion from Parietal cells), gets converted to the active enzyme pepsin because HCL provides necessary acidic environments where pepsin work best. Then Pepsin hydrolyzed the proteins to polypeptide and starts protein digestion in the stomach.
Answer:The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential.
