The space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. How can the program's doctors make sure the astronauts’ bodies work well enough to exercise in space?
The doctors could make sure that the astronauts’ bodies can make enough energy by getting enough sleep.
The doctors could make sure the astronauts’ stomachs are getting the molecules they need from food and air.
The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air.
The doctors could make sure the astronauts’ cells are getting different types of molecules from food.
What is a calorie?
A chemical substance that provides nourishment essential for growth and the maintenance of life.
Organic nutrients of various forms that the body requires in very small amounts.
A unit of energy equivalent to the energy needed to raise 1kg of water 1 degree celsius.

An athlete thinks that she can exercise as long as she eats different types of food because her body just needs different types of food molecules to work properly. Is the athlete correct?
Yes, her cells only work when they have molecules from different types of food.
No, her muscles do not need molecules from food because all cells make all the molecules they need.
No, all cells need molecules from food and molecules from air to work properly.
No, only her stomach cells need food molecules to work properly.
Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?
Yes, her cells just need to combine amino acids to release energy.
No, her cells need to combine glucose into starch molecules to release energy.
No, her cells need glucose to react with oxygen to release energy.
Yes, her cells just need oxygen to release energy.
Doctors tested a patient to find out what molecules were in his cells. His cells contained normal levels of glucose molecules and amino acid molecules, and low levels of oxygen molecules. Will this patient be able to exercise normally?
Yes, his body is working properly enough to exercise.
No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
No, his body systems are working, but he needs to eat different food; only proteins can react with glucose to release energy.
No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.
