Detailed explanation-1: -Mitochondria are involved in different cellular functions, but they are essentially responsible for cellular ATP production through the so-called oxidative phosphorylation (OXPHOS). This process occurs in the inner mitochondrial membrane (IMM) in specific dynamic membrane invaginations called cristae.
Detailed explanation-2: -The inner membrane of the mitochondrion contains the components of the electron transport chain. Oxidation/reduction reactions along the components of the electron transport chain generate a proton gradient that is used by ATP synthase to phosphorylate ADP, thereby producing ATP.
Detailed explanation-3: -Krebs Cycle (also known as the Citric Acid Cycle): Uses the pyruvate molecules from Glycolysis to generate 2 ATP as well as several molecules of FADH2 and NADH for the electron transport chain. Krebs Cycle takes place in the mitochondrial matrix and requires oxygen.
Detailed explanation-4: -Protons pass Fo via subunit a to the c-ring (Wittig and Schagger 2008). Rotation of subunit within the F1 33 hexamer provides energy for ATP synthesis. This is called “rotary catalysis” (Devenish et al.
