Answer 1

Structure A is ATP synthase, an enzyme critical for ATP production during aerobic respiration, located on the cristae of the mitochondrial inner membrane.

Step-by-step explanation:

The bulb-like structure with a port connecting the intermembrane space and mitochondrial matrix on the mitochondrial membrane is ATP synthase. ATP synthase is an enzyme that plays a critical role in the production of ATP (adenosine triphosphate), which is the major energy currency of the cell. The mitochondrial membrane consists of two separate phospholipid bilayers. The inner membrane, which has many folds called cristae, increases the surface area available for ATP synthesis. These cristae are key structures in the process of aerobic respiration, facilitating the production of ATP by hosting the integral proteins that make up the electron transport chain.

Answer 2

The correct answer is ATP synthase.

ATP synthase is an enzyme located in the inner mitochondrial membrane, that creates the energy storage molecule adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate (Pi). ATP synthesis occurs during cellular respiration thanks to electrochemical gradient which is created by the difference in proton (H+) concentration across the mitochondrial membrane.
