True or False: FADH2 is one of the products of the citric acid cycle.

FADH2 is indeed one of the products of the citric acid cycle, also known as the Krebs cycle or TCA cycle. During this cycle, succinate is oxidized to fumarate, and in this process, FAD (flavin adenine dinucleotide) is reduced to form FADH2. This molecule is a key electron carrier and plays a crucial role in cellular respiration, especially in the electron transport chain, where it helps to generate ATP.

The citric acid cycle is central in the metabolic pathway that provides energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Through various steps of the cycle, both NADH and FADH2 are produced, which are important for transferring high-energy electrons to the electron transport chain, leading to ATP production.

By confirming that FADH2 is a product of the citric acid cycle, this statement highlights the cycle's pivotal role in energy metabolism and the importance of its byproducts in the overall process of cellular respiration.
