Question

During cellular respiration in mitochondria, the organelle breaks down glucose to release chemical energy. How is the chemical energy used?
The chemical energy is used to form ATP bonds.
The chemical energy is used to form more glucose.
The chemical energy is converted into carbon dioxide.
The chemical energy is converted into oxygen.

Answer 1

Answer:

B.

Explanation:

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

Answer 2

The chemical energy produced in the mitochondria as a result of the breakdown of glucose is used to form ATP bonds.

CHEMICAL ENERGY:

• Cellular respiration is the process whereby living organisms obtain energy needed for metabolic activities by breaking down food molecules in their cells.

• This process of cellular respiration takes place in the mitochondria organelle where glucose is degraded in a series of processes to release the chemical energy stored in its bonds.

• This released chemical energy is used to synthesize an energy carrier molecule called ATP, which is the usable form of energy by living cells.

• Therefore, the chemical energy produced in the mitochondria as a result of the breakdown of glucose is used to form ATP bonds.
