Detailed explanation-1: -Answer and Explanation: Starting with one molecule of glucose, glycolysis results in the net production of 2 NADH, 2 pyruvate, and 2 ATP (answer choice B). The products of glycolysis are then shuttled into the citric acid cycle.
Detailed explanation-2: -Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.
Detailed explanation-3: -The net end products of glycolysis are two Pyruvate, two NADH, and two ATP (A special note on the “two” ATP later). Glycolysis is a process that all organisms undergo; and therefore the most fundamental and primitive of all energy production systems.
Detailed explanation-4: -The Krebs cycle yields three NADH molecules (two cycles) and 18 ATP molecules. In two cycles, four FADH2 molecules are generated, yielding four ATP molecules.
Detailed explanation-5: -Review: In the process of glycolysis, a net profit of two ATP was produced, two NAD+ were reduced to two NADH + H+, and glucose was split into two pyruvate molecules.
