Biology
Which of the following forms of carbohydrates is broken down during respiration ?
- Cellulose
- Glucose
- Starch
- Sucrose
Answer
Glucose
Reason — Respiration is the process in which glucose is broken down to release energy.
Cellulose is a structural carbohydrate found in plant cell walls. It is not used in respiration because most organisms cannot easily break it down. Starch is a storage form of carbohydrate. It must first be converted into glucose before it can be used in respiration. Sucrose is a transport sugar in plants. It is also broken down into glucose (and fructose) before entering respiration.
