Question

Which one of the following cells depends primarily on glucose for energy?

• A. Lymphocyte
• B. Differentiated adipocytes
• C. Matured RBC
• D. Muscle cells

Hint:

Lymphocytes primarily use glucose for energy during immune activation, while other cells may rely more on fats.

Answer 1

The Correct Option is A

Step 1: Understanding Cellular Energy Sources 
Different cells in the body rely on different energy sources depending on their metabolic needs. 
Step 2: Evaluating the Options 
- Lymphocytes: These immune cells primarily rely on glucose for energy, especially during activation. 
- Differentiated adipocytes: These cells store fat and rely on lipids, not glucose. 
- Matured RBC: Red blood cells primarily rely on glucose via anaerobic glycolysis for energy. 
- Muscle cells: Muscle cells use a combination of glucose and fatty acids depending on activity levels. 
Step 3: Conclusion 
Lymphocytes primarily use glucose, especially during immune responses.
