Glycolysis During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60% remains in the products of metabolism is stored as fat. is used to reduce NADP is lost as heat remains in the products of metabolism is stored as fat. is used to reduce NADP is lost as heat ANSWER DOWNLOAD EXAMIANS APP
Glycolysis A kinase is an enzyme that removes water from a double bond removes phosphate groups of substrates uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate removes water from a double bond removes phosphate groups of substrates uses ATP to add a phosphate group to the substrate uses NADH to change the oxidation state of the substrate ANSWER DOWNLOAD EXAMIANS APP

Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? The enzymes of glycolysis only function in one direction High levels of ATP keep the pathway going in a forward direction Glycolysis occurs in either direction There are essentially three irreversible reactions that act as the driving force for the pathway The enzymes of glycolysis only function in one direction High levels of ATP keep the pathway going in a forward direction Glycolysis occurs in either direction There are essentially three irreversible reactions that act as the driving force for the pathway ANSWER DOWNLOAD EXAMIANS APP
