Mo4-L3b: How are the Photosynthesis and Cellular Respiration Related?
Let’s Begin
Cellular Respiration
Cellular respiration is a series of chemical reactions
that convert the energy in food molecules into a
usable form of energy called ATP.
Glucose molecules break down during cellular
respiration.
Plants produce sugar, but without cellular respiration,
plants could not grow, reproduce, or repair tissues.
Key Concept
How are the Photosynthesis and Cellular
Respiration Related?
What is Cellular Respiration?
Most plants, some protists, and some bacteria carry on photosynthesis.
Most organisms carry on cellular respiration. Life on Earth depends on a balance of these two processes.
