Jamal has been feeling tired a lot, so his doctor gave him a test that found that Jamal's cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired? Explain

The question is incomplete the complete question is as follows:

Jamal ate a meal of rice before seeing his doctor. Rice is made of mostly starch molecules. Jamal has been feeling tired a lot, so his doctor gave him a test that found that Jamal’s cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired?

answer choices

Yes, Jamal's respiratory system is working, but his digestive system is not turning the oxygen into glucose.

Yes, Jamal's respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.

Yes, Jamal's digestive system is working, but his respiratory system has too much oxygen, so his body stopped making energy.

No, something else must be wrong with Jamal because his cells have all the molecules they need.

Yes, Jamal's respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.

Explanation:

The cellular respiration can be defined as the process in which the food molecules are broken down into simpler substances by the oxidation and this process results in the release of energy in the form of ATP.

According to the given situation, the cells are showing the normal levels of oxygen this means that the respiratory system is working properly but the glucose levels are low this means that the digestive system is not working properly.

The starch which was the component of food was not broken down into glucose as a result Jamal is feeling tired as no energy produced.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
