Which cell structure plays a direct role in the release of chemicals from the cell?
jonny [76]

Answer:

The correct answer is - the cell membrane.

Explanation:

When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.

Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.

The muscular system helps with <u>movement</u> and the skeletal system helps with <u>structure</u>.

The human muscular system constitutes 40% of the total weight of our body and is made up of three types of muscles, which, together with different tendons and thanks to their contraction capacities, allow us to move. The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.
