B
C
D
Verified step by step guidance1
Recall the overall glycolysis pathway, which converts one molecule of glucose into two molecules of pyruvate, producing energy and reducing equivalents in the process.
Identify the net products of glycolysis per glucose molecule: 2 ATP (net gain), 2 NADH, and 2 pyruvate molecules. Water (H2O) is also produced as a byproduct.
Understand that oxygen (O2) is not produced by glycolysis; instead, it is consumed during aerobic respiration in the mitochondria, specifically in the electron transport chain.
Recognize that the question asks which molecule is NOT a net product of glycolysis, so compare the options to the known glycolysis products.
Conclude that since O2 is not generated but rather used later in aerobic metabolism, it is the molecule that is NOT a net product of glycolysis.
