Question

The end product of glycolysis under aerobic condition is _______

• A. Lactic acid
• B. Pyruvic acid
• C. Acetyl CoA
• D. Citric acid

Hint:

Aerobic glycolysis produces pyruvic acid, while anaerobic glycolysis produces lactic acid.

Answer 1

The Correct Option is B

Concept:
Glycolysis is the process by which glucose is broken down to produce energy. It occurs in the cytoplasm of the cell.

Step 1: Starting molecule of glycolysis.
The starting molecule of glycolysis is glucose. \[ \text{Glucose} \rightarrow \text{Glycolysis} \]

Step 2: End product in aerobic condition.
In the presence of oxygen, glucose is converted into pyruvic acid through glycolysis. \[ \text{Glucose} \rightarrow 2 \text{ Pyruvic acid} \]

Step 3: Further fate of pyruvic acid.
Under aerobic conditions, pyruvic acid enters mitochondria and is converted into acetyl CoA. Then acetyl CoA enters the citric acid cycle.

Step 4: Difference from anaerobic condition.
Under anaerobic condition, pyruvic acid is converted into lactic acid.

Step 5: Final answer.
Therefore, the end product of glycolysis under aerobic condition is pyruvic acid. \[ \boxed{\text{Pyruvic acid}} \]
