Compare photosynthesis and aerobic respiration

Similarities

  • Both are energy converting processes.
  • Both require mechanisms for exchange of carbon dioxide and oxygen.
  • Both processes have a reaction pathway in which ATP is formed i.e. photo phosphorylation and oxidation phosphorylation in photosynthesis and respiration respectively.
  • Bother processes involve enzyme-controlled reactions.
  • Both require special organelles in eukaryotes, chloroplasts for photosynthesis and mitochondria for respiration.
  • Both processes are affected by temperature.

Differences

Aerobic respiration Photosynthesis
A catabolic process (involves breakdown of carbohydrates into simple of sugar) inorganic compounds. An anabolic process which results in synthesis of carbohydrate molecules from simple inorganic compounds.
Energy is incorporated into ATP for immediate use Energy is accumulated and stored in carbohydrates
Oxygen is used up Oxygen is released
Carbon dioxide and water are released Carbon dioxide and water are used up
Process occurs in decrease in dry mass Results in increase in dry mass
Process occurs in mitochondria in eukaryotes Process occurs in chloroplast in eukaryotes
Takes place continuously throughout life and is independent of chlorophyll and light Occurs only in cells possessing chlorophyll and only in the presence of light.
