Question

In many organisms, on both the microscopic and gross levels, there are anatomical structures with specific adaptations to serve to increase surface area in order to facilitate chemical reactions as well as transport mechanisms. What structure listed here is an example of such a surface area adaptation? A) the cristae of mitochondria B) the irregular shape of an amoeba C) the large size of a plant cell vacuole D) the ligand-gate receptors of the cell membrane

Answer 1

A)the cristae of mitochondria

Answer 2

Answer: The answer is A) the cristae of mitochondria

Explanation: Mitochondrial cristae are folds of the inner membrane of the mitochondria that propagate into the lumen. This membrane system has the function of carrying out the transport of electrons during cellular respiration, so it must host a series of enzymes that are responsible for carrying out this transport, which results in the synthesis of ATP (energy) that will be used by the cell for different processes. For this, the surface of this membrane must be wide, and this is achieved thanks to these folds or cristae. The amount of mitochondrial cristae that will have a cell mitochondria depends on the energetic needs of it.
