Cells need energy to function: Just like you
need food for energy, cells need energy to
grow, move, and repair themselves.
Glucose is the fuel: Glucose is a type of sugar
that cells use as their main source of energy.
Aerobic respiration breaks down glucose: In
aerobic respiration, glucose is broken down with
the help of oxygen to release energy.
Carbon dioxide and water are produced:
During this process, carbon dioxide and water
are also produced as waste products.
Where it happens: Most of aerobic respiration
takes place inside tiny structures called
mitochondria within cells.
