3. (04.03 MC) which description properly describes a step involved in cellular respiration? (4 points)
Glucose is created, then the energy gained is transferred to the energy molecule.
Carbon dioxide is combined with oxygen to make glucose.
Water is divided into carbon dioxide and glucose.
Oxygen is combined with the carbon atoms left from the glucose molecule.

Explanation:

Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.

Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product .
