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: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-3: -Answer and Explanation: In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH.

Detailed explanation-4: -Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

Detailed explanation-5: -There are mainly two phases of respiration-glycolysis and Kreb’s cycle. Glycolysis occurs in the cytoplasm of a cell and Kreb’s cycle occurs in the mitochondria of a cell.
