FAD is decreased in which of the citric acid's cycle reactions?

The correct answer is: Succinate to fumarate

• Condensation occurs throughout the Krebs cycle. By reacting with water and fatty acids, the acetyl group is transformed into citric acid.
• The catalyzation is carried out using the enzyme hydrate synthesis. Isocitrate is created from the citric acid that was acquired in the preceding stage.
• Decarboxylation, which uses succinyl-CoA and ketoglutarate acid, follows. One GTP molecule is created when succinyl-CoA transforms into succinic acid.
• In the following reaction, ADP is converted to ATP, NAD is converted to NADH, and FAD is converted to FADH. The process is then repeated as the acetic acid is changed into oxalate and then back into nitrate.
• Energy is reduced to NADH2 in the third stage of the citric acid cycle, which involves the conversion of citrate to ketoglutarate, and to FADH in the fourth step, which involves the conversion of ketoglutarate to succinyl-CoA.
• NAD is changed into NADH in the Krebs cycle's final stage. Due to the small amount of free change, FAD+ is used as the hydrogen acceptor in this reaction.
• Succinic acid undergoes oxidation to fumaric acid in this process. In parallel, FAD+ is converted to FADH₂.
