Answer
A
Explanation
This question is testing the understanding of cellular biology, specifically the function of the mitochondria within eukaryotic cells, such as those found in animals and plants. The functions of the mitochondria include generation of ATP through respiration, execution of metabolic reactions, and the regulation of cellular metabolism.Option A "Aerobic respiration" refers to the process by which cells produce energy through the breaking down of molecules in the presence of oxygen. This is known to occur within the mitochondria.Option B "Crossbridge formation" refers to the interactions between actin and myosin, which are involved in muscle contractions. This process does not happen in mitochondria.Option C "Fertilisation" is the process of fusion of male and female sex cells. This is a genetic event and not related to the function of mitochondria.Option D "Phagocytosis" refers to the mechanism by which certain cells in an organism ingest other cells or extraneous organic material.It does not occur in the mitochondria.Among the options provided, the process that happens inside mitochondria is aerobic respiration.
