Given below are two statements: Statement (I): The rate of glycolysis is controlled by ATP consumption, NAD^++H^+ regeneration and enzymes like hexokinase, pyruvate kinase etc. Statement (II): It is also controlled by hormones like glucagon, epinephrine and insulin. In light of the above statements, choose the most appropriate answer from the options given below.

Step-by-step solution

Statement (I) is correct because the rate of glycolysis is fundamentally controlled by the cellular energy charge, including ATP consumption and the continuous need for NAD^+ regeneration from NADH + H^+ . The process is strictly regulated by key allosteric enzymes such as hexokinase, phosphofructokinase, and pyruvate kinase. Statement (II) is correct because glycolysis is also subject to hormonal regulation to maintain systemic blood glucose homeostasis. Hormones like insulin upregulate glycolysis by promoting the
