Question
Biology Question on respiration in plants
Hibernating animals have tissues containing mitochondria with a membrane protein that accelerates electron transport while blocking the synthesis of ATP. What is the consequence of this?
A
Hibernating animals can synthesize fat instead of wasting the energy of respiration.
B
Energy is saved because glycolysis and the citric acid cycle shuts down.
C
Pyruvate is converted to lactic acid by anaerobic fermentation
D
The energy of respiration is converted into heat.
Answer
The energy of respiration is converted into heat.
Explanation
Solution
Answer (D): The energy of respiration is converted into heat.
In the tissues of hibernating animals, the mitochondria have a membrane that accelerates electron transport, which blocks the synthesis of ATP. This process is known as "uncoupling.”.
- It allows mitochondria to release energy in the form of heat instead of storing it as ATP.
- Due to this, body temperature remains constant without consuming more stored energy.
