NEET Botany Question (2024) — Solution

Question

Identify the step in tricarboxylic acid cycle, which does not involve oxidation of substrate.

Options

  1. A. Succinic acid Malic acid
  2. B. Succinyl-CoA Succinic acid
  3. C. Isocitrate -ketoglutaric acid
  4. D. Malic acid Oxaloacetic acid

Answer

B. Succinyl-CoA Succinic acid

Step-by-step solution

Oxidation involves the loss of electrons (often as part of hydrogen) from a molecule, leaving to an increase in its oxidation state. This process is typically associated with the transfer of electrons to an electron acceptor which is reduced in the process. The conversion of succinyl CoA to succinic acid does not involve oxidation of substrate.
