Substrate level phosphorylation or the direct transfer of a
phosphate occurs in which of the following metabolic pathway(s) -
ANSWER--glycolysis
-kreb's cycle
Oxidative phosphorylation or the indirect transfer of a phosphate
happens in which of the following metabolic pathway(s) -
ANSWER-electron transport chain
NADH is produced in which of the following step(s) of glucose
metabolism. - ANSWER--glycolysis
