Question

1. doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. will this patient be able to exercise normally?

a yes, the glucose and oxygen molecules can react together to release energy for the body to function.
b no, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
c no, his body systems are working, but he needs to eat different food; in cells, only amino acids can react with oxygen to release energy.
d yes, as long as his cells have glucose, they dont need anything else to release energy for the body to function.

Explanation:

Cellular respiration is the process by which cells generate energy. The equation for aerobic cellular respiration is \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2 + 6H_2O+\text{Energy}\). Glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)) are the reactants. Starch is a polysaccharide that is broken down into glucose in the digestive system. Since the patient has normal levels of glucose (the monomer for energy - related reactions in cellular respiration) and oxygen (required for aerobic respiration), the reaction can occur.
Option b is wrong because starch is not a reactant in cellular respiration (it is broken down to glucose). Option c is wrong because amino acids are not the main molecules that react with oxygen for energy release in normal cellular respiration (glucose is the primary one in most cases). Option d is wrong because oxygen is also required for aerobic cellular respiration (the release of a large amount of energy).

Answer:

A. Yes, the glucose and oxygen molecules can react together to release energy for the body to function.
