Question

Name the first breakdown product of glucose during respiration. Where does it take place?

Answer 1

Pyruvate is the first breakdown product of glucose during respiration and this process takes place in the cytoplasm of the organism.

Answer 2

Answer:

The first breakdown product of glucose during respiration is Pyruvate and this breakdown takes place in the cytoplasm of cells.

Explanation:

A sort of oxygen-based breathing is known as aerobic respiration.

• In aerobic respiration, the glucose intake is completely broken down into carbon dioxide and water through oxidation.
• Aerobic respiration produces energy that is stored in ATP molecules for usage by organisms.
• Glycolysis is the initial stage of aerobic respiration, in which a glucose molecule is broken down into two pyruvate molecules.
• As a result, pyruvate is a byproduct of aerobic respiration. This results in the formation of carbon dioxide, water, and energy as the end products.

The reaction involved in this reaction is as follows:

Glucose →  Pyruvate →  $6CO_2 +6H_2O + 38ATP$

• Pyruvate is hence the intermediary product.

• The first stage of glycolysis occurs in the cytoplasm of cells.
• Pyruvic acid reaches mitochondria after glycolysis and the complete process undergoes in Kerb's cycle.
