During cellular respiration, the chemical energy from food is transferred into which of the following molecules that can be used
as an energy source by enzyme throughout the cell? A
Ribonucleic acid (RNA)
B
Adenosine triphosphate (ATP)
C
Deoxyribonucleic acid (DNA
D
Triglycerides
The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP. The organelle called a mitochondrion is the site of the other two stages of cellular respiration
