Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In mitochondria, cristae acts as sites for
A
Protein synthesis
B
phosphorylation of flavoprotein
C
breakdown of macromolecules
D
oxidation of reduction reactions
Explanation: 

Detailed explanation-1: -Mitochondrial cristae are sites for Oxidation reduction reactions. The inner mitochondrial membrane is embedded with the enzyme ATP synthase (ATP synthesis), succinate dehydrogenase (oxidation-reduction reaction) and is also the site of the electron transport chain (aerobic respiration).

Detailed explanation-2: -Electron Transport System (ETS) and Oxidative Phosphorylation.

Detailed explanation-3: -Oxidative phosphorylation occurs in the crista of mitochondria, formed by invaginations of the inner mitochondrial membrane (Figure 5). The hydrogen accepted by NAD+ and FAD during glycolysis and the TCA cycle is oxidized to water by molecular oxygen accompanying phosphorylation of ADP
