What is the definition of cellular respiration? ( 1 point )
A.) the process of capturing the sun's energy, converting it into sugar, and storing it in tissue.
B.) the process of using the chemical energy from food and oxygen molecules to power life processes.
C.) the process of using the chemical energy from hydrogen and oxygen to power life process
D.) the process of capturing the sun's energy, converting it into oxygen, and releasing it into the atmosphere.
B.) the process of using the chemical energy from food and oxygen molecules to power life processes.
The correct definition of cellular respiration is B.) 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.
To find the correct answer, you can break down the options and analyze each one:
A.) The process described here is photosynthesis, not cellular respiration. Photosynthesis is the process by which plants convert sunlight into energy and store it as sugar.
B.) This option correctly describes cellular respiration. It states that cellular respiration involves using the chemical energy from food and oxygen to power life processes.
C.) This option does not accurately describe cellular respiration. It mentions the use of hydrogen and oxygen, but it does not cover the energy source from food.
D.) This option describes the process of photosynthesis, not cellular respiration. It describes capturing the sun's energy and releasing oxygen into the atmosphere, which are the key steps of photosynthesis.
By eliminating options that do not accurately represent cellular respiration and comparing the remaining options, we can see that option B is the correct definition.
