A) The first step of glycolysis involves oxidative phosphorylation.
B) The glycolytic pathway is cyclical.

E) Two NADH molecules are reduced during glycolysis.

Question

Quizplus · Accepted Answer

Glucose activation in glycolysis involves substrate-level phosphorylation, where phosphate groups are transferred from high-energy compounds (like ATP) to glucose, making it more reactive. This is essential for the initial steps of glycolysis, where glucose is phosphorylated to glucose-6-phosphate.
