Detailed explanation-1: -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-2: -The electron transport chain (ETC) is the last step of cellular respiration and is an aerobic process because it cannot function without oxygen. This final step of cellular respiration takes place in the inner mitochondrial membrane.

Detailed explanation-3: -In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH. The formed FADH2 and NADH then go into the inner mitochondrial membrane where they are involved in the electron transport chain to form more ATP molecules.

Detailed explanation-4: -Anaerobic respiration is a type of cellular respiration where respiration takes place in the absence of oxygen. It takes place in the cytoplasm since most anaerobic cells do not have specialized organelles whereas aerobic respiration takes place in the mitochondria.

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.
