Starting with one molecule of glucose, glycolysis results in the net production of which of the following sets of energy-containing products?
A) 2 NAD⁺, 2 pyruvate, and 2 ATP
B) 2 NADH, 2 pyruvate, and 2 ATP
C) 4 NADH, 2 pyruvate, and 4 ATP
D) 6 CO₂, 2 pyruvate, and 2 ATP

Question

Quizplus · Accepted Answer

Glycolysis results in the net production of 2 ATP and 2 NADH from one molecule of glucose. Pyruvate is also produced, but not as an energy-containing product. NAD⁺ is consumed in the process, not produced. Choice A is incorrect because it lists NAD⁺ as a product, which is not produced but consumed. Choice C is incorrect because it lists 4 NADH, which is not the net production from one molecule of glucose, and 4 ATP, which is incorrect as glycolysis only produces 2 ATP. Choice D is incorrect because it lists the products of cellular respiration, not just glycolysis.
