What is the role of oxygen in aerobic respiration? (2019)

Step 1: Understand that aerobic respiration is a process that cells use to produce energy.
Step 2: Know that this process occurs in the presence of oxygen.
Step 3: Learn that during aerobic respiration, glucose is broken down to release energy.
Step 4: Recognize that electrons are transferred through a series of proteins in a part of the cell called the electron transport chain.
Step 5: Identify that oxygen is needed at the end of this chain.
Step 6: Understand that oxygen accepts the electrons after they have passed through the chain.
Step 7: Realize that when oxygen accepts these electrons, it helps to form water, which is a byproduct of the process.
Step 8: Conclude that without oxygen, the electron transport chain cannot function properly, and energy production is reduced.
