AP BIOLOGY

Detailed explanation-1: -The mitochondrion is referred to as the ‘power house’ of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. The inner membrane of the mitochondrion contains the components of the electron transport chain.

Detailed explanation-2: -ATP synthesis occurs on the inner membranes of the mitochondrion. The energy released during respiration is conserved as ATP. Most ATPs are synthesised in the inner mitochondrion during the electron transport system.

Detailed explanation-3: -The ATP synthases comprise a very large group of highly conserved enzymes that are found in the bacterial cytoplasmic membranes, the thylakoid membranes of chloroplasts, and the inner membranes of mitochondria.

Detailed explanation-4: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
