A) What is the definition of cellular respiration? (1 point)

the process of using the chemical energy from hydrogen and oxygen molecules to power life processes
the process of using the chemical energy from food and oxygen molecules to power life processes
the process of capturing the sun’s energy, converting it into oxygen, and releasing it into the atmosphere
the process of capturing the sun’s energy, converting it into sugar, and storing it in tissues

the process of using the chemical energy from food and oxygen molecules to power life processes

B) The correct answer is: the process of using the chemical energy from food and oxygen molecules to power life processes.

To determine the correct answer, you need to understand the concept of cellular respiration. Cellular respiration is the process by which living organisms, such as plants and animals, convert the chemical energy stored in food molecules into a form usable by cells, called adenosine triphosphate (ATP). This process typically requires oxygen and occurs in the mitochondria of cells.

Option A is incorrect because cellular respiration does not directly use the chemical energy from hydrogen and oxygen molecules, but rather from food molecules.

Option C is incorrect because capturing the sun's energy and releasing it into the atmosphere is describing photosynthesis, not cellular respiration.

Option D is incorrect because capturing the sun's energy, converting it into sugar, and storing it in tissues is also describing photosynthesis, not cellular respiration.

Therefore, option B is the correct answer as it accurately describes cellular respiration as the process of using the chemical energy from food and oxygen molecules to power life processes.

The correct answer is:

B) the process of using the chemical energy from food and oxygen molecules to power life processes
