Front

How can doctors tell if an ocean scientist's body is healthy enough for underwater tasks?

Back

The doctors could see if her cells are getting the molecules they need from food and air.

Front

A patient has normal amino acids and oxygen, but low glucose in her cells. Can she exercise normally?

Back

No, her cells need glucose to react with oxygen to release energy.
