Detailed explanation-1: -The electrochemical proton gradient across the inner mitochondrial membrane is used to drive ATP synthesis in the critical process of oxidative phosphorylation (Figure 14-14). This is made possible by the membrane-bound enzyme ATP synthase, mentioned previously.
Detailed explanation-2: -The mitochondria are small organelles floating freely throughout the cell. Mitochondria utilize oxygen to produce ATP in cellular respiration. These membrane-bound cell organelles synthesize the energy required for cellular activities or biochemical reactions.
Detailed explanation-3: -Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.
Detailed explanation-4: -Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Detailed explanation-5: -The reactants of cellular respiration vary at each stage, but initially, it requires an input of glucose, ATP, and NAD+. NAD+, a nicotinamide derived from vitamin B3, is a universal electron acceptor that is crucial in the process of cellular respiration.
