Thermodynamics for Physiology: The Energetics of (Bio)Chemical Reactions

Practice: Bringing an amino acid from the inside of the small intestine to the bloodstream requires the use of a Na+- amino acid cotransporter. The work done by this transporter in moving the amino acid into the cell is an example of which kind of work?

Practice: The first reaction in glycolysis is the addition of a phosphate group to glucose, making glucose-6-phosphate. This reaction requires hydrolyzing ATP→ADP. Which of the following describes the energetics of this reaction?

Practice: This is a reaction coordinate diagram for a reaction run with or without an enzyme catalyst present.
