Verified step by step guidance1
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 outputs of the Krebs cycle: The primary products of the Krebs cycle are ATP, carbon dioxide (CO2), NADH, and FADH2.
Focus on the molecules released: Besides ATP, the Krebs cycle releases carbon dioxide as a waste product and NADH as an electron carrier.
Eliminate incorrect options: Water and NADPH, Glucose and ADP, and Oxygen and FADH2 are not the correct combinations of molecules released during the Krebs cycle.
Conclude with the correct answer: The two other molecules released during the Krebs cycle, besides ATP, are carbon dioxide and NADH.
