MICROANATOMY

Detailed explanation-1: -Electron transport and oxidative phosphorylation are critical activities of protein complexes in the inner mitochondrial membrane, which ultimately serve as the major source of cellular energy.

Detailed explanation-2: -In eukaryotes, the mitochondria are the site of oxidative metabolism. As with photosynthesis, inorganic elements play essential roles in respiration. In the initial stages of respiration, glucose is broken down into two pyruvate molecules, C3H3O3−, in a process termed glycolysis.
