The process by which ADP phosphorylated by Pi (inorganic phosphate) to ATP in the electron transport chain is known as _____

Correct option is A

Ans (a)
Sol. Oxidative phosphorylation: This is the process in which ADP is phosphorylated to form ATP using energy derived from the electron transport chain, primarily in the mitochondria. It involves the transfer of electrons through a series of protein complexes and the production of ATP by ATP synthase, driven by a proton gradient. This is the correct answer.
Oxygenases: These are enzymes that incorporate oxygen into a substrate during a biochemical reaction. They are not related to ATP synthesis through the electron transport chain.
Hydroperoxidases: These are enzymes that reduce hydroperoxides (compounds containing an oxygen-oxygen bond), but they are not involved in ATP production via the electron transport chain.
Oxidases : These are enzymes that catalyze oxidation reactions, typically involving the transfer of electrons to oxygen. However, they do not refer to the specific process of ADP phosphorylation in the electron transport chain.
