Session Overview


This session will introduce basic ideas of metabolism, Gibbs free energy, biochemical reactions, enzymes and ATP as the energy currency.

Learning Objectives

  • To understand that organisms, through their biochemistry, transform matter and energy.
  • To apply the general laws of thermodynamics to biological reactions.
  • To define Gibbs free energy, determine the Gibbs free energy change associated with a biochemical reaction, and identify spontaneous and non-spontaneous reactions.
  • To understand the role that enzymes play in biochemical reactions.
  • To understand how ATP provides the energy to power cellular work.
