Questions & Step-by-Step Solutions

What is produced during the decarboxylation of isocitrate?
  • Step 1: Understand that isocitrate is a molecule involved in the Krebs cycle (a part of cellular respiration).
  • Step 2: Know that decarboxylation is a chemical reaction where a carboxyl group (COOH) is removed from a molecule.
  • Step 3: When isocitrate undergoes decarboxylation, it loses one carbon atom in the form of carbon dioxide (CO2).
  • Step 4: During this process, another molecule called NAD+ is converted into NADH, which is an important energy carrier in cells.
  • Step 5: Therefore, the products of the decarboxylation of isocitrate are NADH and CO2.
