Detailed explanation-1: -Through the process of glycolysis, one molecule of glucose breaks down to form two molecules of pyruvate.
Detailed explanation-2: -1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
Detailed explanation-3: -Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.
Detailed explanation-4: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
