Study Notes

Photosynthesis

  • Photosynthesis is a biological process that converts light energy into chemical energy, stored in organic compounds.
  • The process fuels the organism's activities through cellular respiration.
  • Oxygenic photosynthesis produces oxygen as a byproduct and stores chemical energy in carbohydrates, such as sugars, starch, glycogen, and cellulose.
  • These carbohydrates are synthesized through an endergonic reaction of carbon dioxide with water.

Organisms that Perform Photosynthesis

  • Most plants, algae, and cyanobacteria are photoautotrophs that perform photosynthesis.
  • Some bacteria also perform photosynthesis, but use bacteriochlorophyll to split hydrogen sulfide instead of water.

Importance of Photosynthesis

  • Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere.
  • It supplies most of the biological energy necessary for complex life on Earth.
