Which molecule serves as the final electron acceptor in the electron transport chain?

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.
