1. Metabolism and Chemical Reactions

Key Concepts & Definitions

  • Metabolism : the set of chemical reactions through which the cells of an organism produce and/or use energy, while transforming matter
  • Enzyme : a catalyst that facilitates a chemical reaction in a cell without being presented as a reactant

★ Must-know

📌 Anabolism consists of synthesis pathways that build molecules, whereas catabolism consists of degradation pathways that break molecules down.

Further detail

  • A molecule is a group of atoms joined by chemical bonds, whereas an atom is the smallest part of a simple body that can chemically combine with another atom.
