The glycolytic pathway (glucose → 2 pyruvate) is found primarily in animals excluding particles only in eukaryotes only in yeast in all living organisms TRUE ANSWER : ? YOUR ANSWER : ?
In glycolysis, ATP is formed by the transfer of a high-energy phosphate from 1,3-bisphosphoglycerate to ADR No such high-energy phosphate donor has ever been isolated in mitochondria because the high-energy phosphate donor is very short-lived and difficult to isolate no such phosphate donor exists None of these the techniques for isolating the phosphate donor are not refined enough TRUE ANSWER : ? YOUR ANSWER : ?
During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% is lost as heat is stored as fat. is used to reduce NADP remains in the products of metabolism TRUE ANSWER : ? YOUR ANSWER : ?
