How many electrons are released in each turn of the TCA cycle?
Each turn of the TCA cycle releases a total of 8 electrons, with 6 from NADH and 2 from FADH2. What is the first phase of the Citric Acid Cycle?
The first phase of the Citric Acid Cycle is citrate formation, where oxaloacetate reacts with acetyl CoA to form citrate. Which high-energy molecules are produced during the Citric Acid Cycle?
The Citric Acid Cycle produces NADH, FADH2, and ATP as high-energy molecules. What type of reaction occurs in the conversion of citrate to isocitrate?
The conversion of citrate to isocitrate involves an isomerization reaction. How many NADH molecules are produced in one turn of the Citric Acid Cycle?
One turn of the Citric Acid Cycle produces 3 NADH molecules. What is the role of FAD in the Citric Acid Cycle?
FAD acts as an electron carrier, being reduced to FADH2 during the conversion of succinate to fumarate. What is the final product regenerated at the end of the Citric Acid Cycle?
Oxaloacetate is regenerated at the end of the Citric Acid Cycle. Which reaction in the Citric Acid Cycle produces ATP?
ATP is produced during the hydrolysis reaction where succinyl CoA is converted to succinate. What is the significance of decarboxylation in the Citric Acid Cycle?
Decarboxylation reactions release carbon dioxide and are crucial for the oxidation steps in the cycle. How many FADH2 molecules are produced in two turns of the Citric Acid Cycle?
Two turns of the Citric Acid Cycle produce 2 FADH2 molecules.
