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: -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-3: -The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria. These aerobic phases are the Krebs Cycle and the electron transport chain.
Detailed explanation-4: -In the cell, Aerobic respiration occurs within the mitochondria, and the anaerobic respiration occurs within the cytoplasm of a cell.
Detailed explanation-5: -Here, oxygen acts as an electron acceptor. The ATP molecules produced as a result of this process are used to produce energy. Mitochondria are the site of aerobic respiration. It is a membrane-bound organelle found in all cells except red blood cells.
