Question

1. a patient has been eating healthy foods, but her respiratory system is not working as well as it usually does. can this patient still exercise normally?

yes, her body can get everything it needs for energy from molecules in food
no, her respiratory system does not have enough oxygen to combine together to release energy
no, her cells do not have enough oxygen to react with glucose and release energy
no, her cells do not have enough oxygen to react with proteins to release energy

Explanation:

To determine the answer, we analyze cellular respiration. Cells need oxygen to react with glucose (from food) to release energy (via aerobic respiration). The respiratory system supplies oxygen. If it's not working well, cells lack enough oxygen for glucose - oxygen reaction.

• Option 1 is wrong: Body needs oxygen (from respiratory system) to release energy from food molecules.
• Option 2 is wrong: Oxygen doesn't "combine together" to release energy; it reacts with glucose.
• Option 4 is wrong: Cells use glucose (not proteins as primary energy source in this context) with oxygen for energy.
• Option 3 is correct: Without enough oxygen from a faulty respiratory system, cells can't react oxygen with glucose to release energy, so normal exercise isn't possible.

Answer:

C. No, her cells do not have enough oxygen to react with glucose and release energy
