Question

Certain cells that line the stomach synthesize a digestive enzyme and secrelc il into the stomach. This enzyme is a protein (bulk molecule).

1. Which of the following processes could be responsible for its secretion?
O endocytosis
O exocytosis
O diffusion
O pinocytosis

Answer 1

Answer: The process responsible for the secretion of the digestive enzyme is EXOCYTOSIS

Step-by-step explanation:

Exocytosis refers to the process by which materials from within the cell is then transported to the exterior of the cell. This procedure needs energy and is genuinely a type of active transport.

It is a necessary process of both animal and plant cells. It does the opposite task of endocytosis which is known for conveying of substances into the cell from the exterior of the cell.

Exocytosis performs many vital functions. It enables cells to produce substances and molecules like protein and hormones. It is very necessary for cell to cell communication and even chemical signal messaging. It is important in rebuilding cell membrane by fixing proteins and lipids taken away by endocytosis back into the membrane.

Now with regards to the stomach, the process responsible for the secretion of certain digestive enzyme by cells that line the human stomach is exocytosis

Answer 2

The correct answer is exocytosis

Step-by-step explanation:

Exocytosis is a process that ensures that the cell expels some substances from its interior, which may be residues from the process of intracellular digestion or substances produced by it.

For example, pepinogens that are contained in zymogen granules in peptic cells are released by exocytosis.
