Answer:
The primary purpose of cellular respiration is to release energy from food molecules.
Explanation:
All organisms obtain the energy for their functioning, from the food they consume. Cells in the body of the organisms produce this energy by converting the energy stored in the food nutrients into a more usable form called adenosine triphosphate (ATP), which will release energy when the need arise. This process is known as cellular respiration. Some prokaryotic organisms use anaerobic respiration (oxygen not required), while others use aerobic respiration (oxygen-requiring) for energy production. In aerobic respiration, ATP is produced by the breaking down of glucose and oxygen into carbon dioxide and water. Mitochondria in the eukaryotic cells are responsible for this process, so they are called the powerhouses of the cell.
In a living organism, the food and nutrient get broken into smaller molecules that produce energy for the cell functioning by the process of cellular respiration.
The correct answer is:
Option b. To release energy from food molecules.
This can be explained as:
- The organism consumes food to gain energy from different sources. This food gets processed and broken into molecules to release energy.
- The energy stored in the food molecules is converted to usable form by the cell called ATP.
- In the presence of oxygen, glucose breaks into the water, carbon dioxide and ATP molecules.
- The process of cellular respiration occurs in the mitochondria of the cell.
Therefore, cellular respiration is a process in which energy is released from the food molecules.
