Detailed explanation-1: -Complete step by step answer: Mitochondria is the site where aerobic respiration occurs. The phases of aerobic respiration that occurs are glycolysis, Kreb’s cycle and the electron transport chain. It is a membrane-bound organelle present in all cells except red blood cells.

Detailed explanation-2: -Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.

Detailed explanation-3: -Mitochondria are best known for their role in ATP synthesis by oxidative phosphorylation. In this pathway, pyruvate from glycolysis is imported into mitochondria where it is oxidatively decarboxylated to acetyl-CoA by pyruvate dehydrogenase (PDH) and fed into the Krebs cycle to produce NADH and FADH2.

Detailed explanation-4: -A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.

Detailed explanation-5: -Mitochondria, Golgi body and ER are organelles of eukaryotic organisms. Since anaerobic bacteria is prokaryotic, they are absent in anaerobic bacteria.
