Verified step by step guidance

Understand the citric acid cycle: The citric acid cycle, also known as the Krebs cycle, is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

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

Analyze the options given: The options provided are NADH, ATP, Glucose, and FADH2.

Determine which option is not a product: Compare the options with the known products of the citric acid cycle. NADH, ATP, and FADH2 are all products of the cycle.

Conclude the answer: Glucose is not a product of the citric acid cycle. Instead, it is a substrate that is broken down in earlier stages of cellular respiration to eventually enter the citric acid cycle as acetyl-CoA.
