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: -Cellular respiration takes place in the cytoplasm and mitochondria of each cell of the body. Glycolysis occurs inside the cytoplasm, while the TCA cycle occurs inside the matrix of the mitochondria.
Detailed explanation-3: -The mitochondrion is known for providing the cell with energy because most of cellular respiration occurs within its membranes. Cellular respiration converts glucose into adenosine triphosphate (ATP). ATP is the energy currency of cells.
Detailed explanation-4: -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-5: -Reason: Aerobic respiration takes place in mitochondria, whereas anaerobic respiration occurs in the cytoplasm.
