6. A patient has been eating healthy foods, but his digestive system is not doing what it usually does. Can this patient still exercise normally?

This question is not complete as it lacks options. The options are:

A) Yes, as long as he can still breathe, his cells will have all the molecules they need to release energy.

B) No, his digestive system is not breaking down oxygen into molecules small enough to get inside his cells.

C) No, molecules from food are not combining together to be large enough for his cells to use.

D) No, molecules from food are not getting broken down small enough to get inside his cells.

The answer is D

Explanation:

Digestion is a very vital metabolic (catabolic) process in living organisms. It is very true that food is needed in order to obtain energy, however, that complex food molecule must be broken down into simpler ones via the process of DIGESTION in order for it to enter our cells and be used in the process that synthesizes energy (cellular respiration).

In this case, a patient is said to have been eating healthy foods but his digestive system is not functioning optimally (normally). This means that the patient's body cannot breakdown the healthy food into simpler molecules (glucose) thatt can enter into his cells for energy to be produced. Therefore, for this reason, the patient cannot exercise normally.

d. organisms have cells with different shapes and functions.
