Questions & Step-by-Step Solutions

Which molecule serves as the final electron acceptor in the electron transport chain?
  • Step 1: Understand that the electron transport chain is a series of proteins in the cell's mitochondria.
  • Step 2: Know that electrons are passed along these proteins during cellular respiration.
  • Step 3: Identify that at the end of this chain, the electrons need to be accepted by a molecule.
  • Step 4: Recognize that oxygen is the molecule that accepts these electrons.
  • Step 5: Learn that when oxygen accepts the electrons, it combines with hydrogen to form water.
