Verified step by step guidance

Understand the Krebs cycle: The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins into carbon dioxide.

Identify the main products of the Krebs cycle: The primary products of the Krebs cycle include NADH, FADH2, ATP (or GTP), and carbon dioxide (CO2).

Analyze each option: Review each of the given options to determine if they are products of the Krebs cycle.

Option 1 - NADH: NADH is indeed a product of the Krebs cycle, as it is generated during the conversion of isocitrate to alpha-ketoglutarate and other steps.

Option 2 - Glucose: Glucose is not a product of the Krebs cycle. Instead, it is a substrate that is broken down during glycolysis before entering the Krebs cycle as acetyl-CoA.
