Question

cellular respiration and matter quick check
what is the definition of cellular respiration? (1 point)
o the process of capturing the suns energy, converting it into sugar, and storing it in tissues
o the process of capturing the suns energy, converting it into oxygen, and releasing it into the atmosphere
o the process of using the chemical energy from hydrogen and oxygen molecules to power life processes
o the process of using the chemical energy from food and oxygen molecules to power life processes

Explanation:

Cellular respiration is the metabolic process in which cells use the chemical energy stored in food (organic molecules) and oxygen to produce ATP (adenosine - triphosphate), which powers life processes. The first two options describe photosynthesis. The third option about hydrogen and oxygen is incorrect as it's not the main description of cellular respiration. The correct one is using energy from food and oxygen.

Answer:

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