To determine what glycolysis produces for each glucose molecule, we need to rationalize the process. Glycolysis is the first step in cellular respiration, which occurs in the cytoplasm of cells. It is a series of reactions that converts glucose into pyruvate, producing a small amount of energy in the form of ATP and reducing equivalents in the form of NADH.
Let's break down the process step-by-step:
1. Glycolysis starts with one molecule of glucose (C6H12O6). During the initial steps of glycolysis, glucose is phosphorylated and converted into two molecules of glyceraldehyde-3-phosphate (G3P).
2. Each G3P molecule is then oxidized, resulting in the production of 2 ATP molecules (in the form of substrate-level phosphorylation) and 2 NADH molecules (by reducing NAD+ to NADH). This step also involves the conversion of G3P to pyruvate, which is a 3-carbon molecule.
So, the correct answer is: 2 ATPs and 2 NADH.
Note: The other options provided are not accurate. The second option includes 1 FADH, which is incomplete, and the third option only includes NADH and FADH2, neglecting the ATP production. The last option includes an excessive amount of ATP, NADH, and FADH2, which is not representative of the actual yield of glycolysis.
