Detailed explanation-1: -So, the given statement is false.
Detailed explanation-2: -ATP is an unstable, high-energy molecule that provides body cells with a form of energy that is immediately usable.
Detailed explanation-3: -The final end products of cellular respiration are ATP and H2O. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH, and two H2O. Therefore, without the presence of oxygen, glycolysis is the only process that can occur, and only two ATP molecules may be produced for each glucose molecule.
Detailed explanation-4: -ATP is not used in the Krebs Cycle, and Its process occurs in the presence of oxygen. It contains Respiratory substrate acetyl coenzyme (A). The Krebs produced 24 ATP molecules from the glucose molecule in the cycle.
Detailed explanation-5: -ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis.
