Answer: Both A and B

Explanation:

Active Transport uses ATP or energy for molecules to move against the concentration gradient when crossing the cell membrane

Passive Transport requires no energy as molecules or solutes will move down the concentration gradient when crossing the cell membrane

During Facillitated diffusion molecules attach to a carrier protein and move down the concentration gradient and therefore requires no energy. This is passive transport.

During Osmosis, water will cross the membrane and move from a less concentrated solution to a more concentrated solution and also requires no energy. This is passive transport.

Finally, during endocytosis, this is a type of active transport whereby large particles or parts of cells are moved across the cell membrane. The engulfing of large particles requires energy (ATP).

Pepsin, a digestive enzyme that degrades proteins in the stomach, is synthesized as pepsinogen and converted to active pepsin in

kipiarov [429]

Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.

<h3>What is pepsin?</h3>

Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.

This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.

Pepsinogen gets active and forms pepsin.

Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.
