Comparing photosynthesis & cellular respiration

Cellular Respiration

The process where cells get their energy in the form of ATP.

Key points for Cellular Respiration.

Anaerobic- Metabolic process that does not require oxygen.

Aerobic- Metabolic process that requires oxygen.

Equation- C6H12O6 + O2(yields to) 6CO2 + 6H2O + energy

Oxygen makes it more efficient, but it can be done without it.

Process

  • The first step for Cellular Respiration starts with Glycolosis
  • The second step is the Krebs Cycle
  • Third step is the Electron Transport Chain.

Photosynthesis

The process where organisms use sunlight to create energy.

Process

  • Step one is the Light Dependent Reaction
  • Step two is the Calvin Cycle
  • Step 3 is the Dark Reaction

Comparing and Contrasting

Photosynthesis and Cellular Respiration

Similarities-

  • Both produce ATP

Differences-

  • Photosynthesis occurs only in plants and Cellular Respiration takes place in plants and animals.
  • Sunlight is not required for Cellular Respiration, but it is for Photosynthesis.
  • Photosynthesis captures energy while Cellular Respiration releases it.
