Metabolism

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 could make sure the astronauts' cells are getting different types of molecules from food.

Would it be difficult for a person with asthma to exercise?

• Yes

• No

What is needed for cellular respiration to occur?

• Oxygen

• Water and Energy

• Glucose

• Oxygen and Glucose

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?

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

• 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; in cells, only amino acids can react with oxygen to release energy.

• Yes, as long as his cells have glucose, they don't need anything else to release energy for the body to function

What molecules should be found in your respiratory system?

• Oxygen, Water, Carbon Dioxide

• Glucose, Water, Oxygen

• Glucose and Oxygen

• Oxygen and Carbon Dioxide

When a protein breaks down, what does it make?

• Starch

• Amino Acids

• Glucose

• Cells

What types of molecules are found in the digestive system?

• Starch and Protein

• Starch, Protein, Amino Acids, Glucose

• Starch, Protein, Amino Acids, Glucose, Fiber

• Starch, Protein, Amino Acids, Glucose, Carbon Dioxide

Sleeping is the only way that our bodies are able to create energy.

• True

• False

A student thinks that the human body only works properly when cells are getting molecules from food and molecules from air. Is the student correct?

• Yes, the body only works when cells get molecules from food and molecules from air.

• No, the body only works when cells are getting molecules from different types of food.

• No, the body only works when the lungs get molecules from air, and the stomach gets molecules from food.

• No, the body works as long as cells are making all the molecules they need.

What is the only system that breaks down molecules?

• Digestive System

• Circulatory System

• Respiratory System
