Detailed explanation-1: -The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.
Detailed explanation-2: -Phase 1: The “Priming Step” The first phase of Glycolysis requires an input of energy in the form of ATP (adenosine triphosphate). alpha-D-Glucose is phosphorolated at the 6 carbon by ATP via the enzyme Hexokinase (Class: Transferase) to yield alpha-D-Glucose-6-phosphate (G-6-P).
Detailed explanation-3: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.
Detailed explanation-4: -Reaction 1: glucose phosphorylation to glucose 6-phosphate. Reaction 2: isomerization of glucose 6-phosphate to fructose 6-phosphate. Reaction 3: phosphorylation of fructose 6-phosphate to fructose 1, 6-bisphosphate. Reaction 4: cleavage of fructose 1, 6-bisphosphate into two three-carbon fragments. More items •06-Feb-2018
