Metabolism Midterm

What should the doctors do to make sure astronauts' bodies can exercise in space?

• Make sure astronauts get enough sleep
• Ensure astronauts' stomachs get the molecules they need
• Ensure astronauts' cells get the molecules they need
• Ensure astronauts' cells get different types of molecules

What would happen if a person ate a lot of glucose-based syrup before exercising?

• It would be harder to exercise because more enzymes are needed
• It would be easier to exercise because glucose moves faster
• Nothing would happen, but the respiratory system wouldn't work as hard
• Nothing would happen, but the digestive system wouldn't work as hard

If a patient has normal oxygen and glucose levels but no starch, will they be able to exercise normally?

• Yes, glucose and oxygen can release energy
• No, cells need starch to react with glucose
• No, only amino acids can react with oxygen
• Yes, as long as there is glucose, nothing else is needed

Why would a digestion problem make it harder to exercise?

• You wouldn't be able to sleep
• Cells wouldn't get enough molecules from food
• You'd need to breathe in more air
• Cells wouldn't get any molecules needed to exercise

Why is a respiratory system problem an issue for exercising?

• The respiratory system can't break down air molecules
• Cells won't work well with low oxygen levels
• The digestive system has to work harder for energy
• Cells can't use the large air molecules

If a patient has normal oxygen but low amino acids and glucose, can they exercise normally?

• Yes, as long as there is oxygen
• No, cells need glucose to react with oxygen
• No, cells need amino acids to react with oxygen
• No, cells need glucose to react with amino acids

Would someone with asthma have difficulty exercising?

• Yes, if they don't get enough sleep
• No, as long as they get different food molecules
• No, their body can still exercise normally
• Yes, their cells need air molecules

Can a patient with a respiratory problem still exercise normally?

• Yes, their body can get energy from food molecules
• No, their respiratory system doesn't have enough oxygen
• No, their cells don't have enough oxygen to react with glucose
• No, their cells don't have enough oxygen to react with proteins

What does a person need from a peanut butter sandwich and the air they breathe to go running?

• the food molecules and oxygen to produce energy
• the food molecules to produce energy, the air doesn't matter
• the food molecules and air molecules to produce energy
• the air molecules to produce energy, the food doesn't matter

Why would low glucose or oxygen make it hard for someone to climb stairs?

• Low glucose or oxygen would make them too tired to exercise
• Low glucose or oxygen would prevent their body systems from working
• Low glucose or oxygen would make them need to breathe more air
• Low glucose or oxygen would prevent their cells from getting the molecules they need
