Botany - Respiration in Plants Question with Solution | TestHub

Respiration is the process or mechanism to break down food molecules to release energy in the form of ATP. During the process of aerobic respiration, phosphorylation of ADP occurs forming the energy currency molecule - Adenosine triphosphate. The energy required for the production of proton gradient which is needed for phosphorylation is obtained from the oxidation-reduction of the molecules. One of the steps of the respiration process is glycolysis where 6C-glucose is broken down to 3C-pyruvate.

Glycolysis is a catabolic process where the substrate glucose is broken down into smaller molecules- pyruvic acid and occurs anaerobically. The site for glycolysis is the cytoplasm. It is a stepwise process involving a series of ten enzymes to catalyze the processes. The first step in glycolysis is the phosphorylation of the glucose molecule to glucose-6-phosphate which is catalyzed by enzyme hexokinase with${\mathrm{M}\mathrm{g}}^{++\; as\; cofactor.}$
