Why does having low levels of glucose or oxygen in his cells make it difficult for Guillermo to walk up steps? Which body systems should the doctor test in order to find out whether Guillermo’s cells are getting enough oxygen and glucose and why?

The reason that having low levels of glucose or oxygen in his cells make it difficult for Guillermo to walk up steps is that these are the two resources that cells use to fuel activity.

In our bodies, the presence of glucose and oxygen is essential for the cells to function. Every cell in our body requires energy to function. Cells get this energy from glucose, but in order to be able to break up the glucose molecules to obtain energy, oxygen is required.

In order to find out whether Guillermo’s cells are getting enough oxygen and glucose, his doctor should test:

The respiratory and circular system should be tested in the case of oxygen, given that oxygen enters the body through the respiratory system, and is then carried to the cells by the circulatory system. The digestive system should be tested to confirm that glucose is being properly absorbed into the body.

The reason that having low levels of glucose or oxygen in his cells make it difficult for Guillermo to walk up steps is that these are the two resources that cells use oxygen to break down glucose in order to function. His doctor will test the digestive, respiratory, and circulatory systems to confirm these resources are in good amounts.
