Glucose metabolism is a cycle of biological processes which can break down glucose molecules to obtain ATPs. It involves three pathways: glycolysis, fermentation, and cellular respiration pathways. Both the glycolysis and fermentation occur in the cytoplasm of a cell that is also termed as cytosol while cellular respiration occurs in the mitochondrial matrix. Kinases and isomerases are the two enzymes involved in glycolysis and fermentation. That functions on either cleaving bonds or shifting the positions of carbon molecules. The final product formed in glycolysis, enters the mitochondria, as cellular respiration takes place in mitochondria. Enzymes present in cellular respiration are mostly dehydrogenated which causes the production of NADH molecules as bi-product.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
