  1. Poisons like cyanide inhibit Na+ efflux and k+ influx during cellular transport. This inhibitary effect is reversed by an injection of ATP. This demonstrates that

    Active transport is the uphill movement of particles against their concentration gradient. Energy is utilised in the form of energy. Cyanide inhibits soluble absorption by lowering respiration rate leading to formation of less ATP. Addition of ATP facilities active transport. Immediate ATP supply minimise the effect of cyanide in normal aerobic respiration.

    Correct Option: A

    During aerobic oxidation of pyruvic acid, first of all there is activation of pyruvic acid in which NAD and coenzyme react with pyruvic acid and oxidative decarboxylation takes place leading to the formation of acetyl Co-A. In this process, lipoic acid amide (LAA), thyamine pyrophosphate (TPP) and NAD are essential to perform this reaction.

    Correct Option: D

    The end product of glycolysis is pyruvate. It enters mitochondria and is oxidatively decarboxylated to acetyl CoA before entering into Krebs cycle.

    Correct Option: D

    The end product of glycolysis is pyruvate. It enters mitochondria and is oxidatively decarboxylated to acetyl CoA before entering into Krebs cycle.
