Question

During the cellular respiration one molecule of glucose is first broken down into two molecules of __________.

Answer 1

During the glycolysis in the first stage of the cellular respiration does not require the oxygen and one Glucose molecule is broken down into the two pyruvate molecules using energy from the 2 ATP during the process 4 ATP and 2NADH molecules generated. On the other side glycolysis occurs in both anaerobic respiration and aerobic respiration. And glycolysis cycles take place in cytoplasm as well as in the mitochondrial matrix.

Complete answer:
Glycolysis is the metabolic pathways that produce energy in the form of ATP in the cellular respiration system. In glycolysis six carbon rings of glucose cleaved into three carbon sugar of pyruvate with the help of enzymatic reactions. In glycolysis, the first step needs energy and the second step converts the pyruvate and produces ATP, NADH and net the two pyruvate molecules two ATP molecules and two NADH molecules present to use energy in the cell. Glycolysis is present in nearly all living organisms and glucose is the source of energy used by the cells. Glycolysis is the cellular metabolic pathways in which sugar glucose, pyruvic acid and ATP as a source of energy. Overall glycolysis produces two pyruvate, ATP, and NADH net gain molecules. Conversation of glucose molecule to pyruvate molecules by the glycolytic pathway that is linked Krebs’s cycle and also produce ATP for the energy source of the cell.

Note: TCA cycle plays a very vital role in the heart of the energetic metabolism and all pathways of the energetic metabolism that’s connected with the TCA cycle MG For e.g. ETC lipogenesis, glycogenesis. The major pathways present in the glycolysis cycle glucose metabolism takes place in the cytosol.
