Similarities Between Photosynthesis And Cellular Respiration

Photosynthesis and cellular respiration are what cells use to “breathe”, or convert one form of energy to another in order to maintain homeostasis. Though these processes seem similar, they actually differ in multiple ways. First, photosynthesis is done by plant cells. They convert water, sunlight, and Carbon Dioxide into Glucose and Oxygen. Photosynthesis is divided into two processes: the light reaction and the Calvin Cycle; they both take place in the Thylakoid Membrane. In the light reaction, sunlight coming in through the stroma and water are converted into Oxygen; this takes place is the chloroplasts. The light reaction also makes ATP and NADPH, which is transferred into the Calvin Cycle. The light reaction synthesizes Carbon to set up the Calvin Cycle. The Calvin Cycle is most important in creating G3P, which is an enzyme that can be quickly arranged into Glucose or Sucrose. If there is not enough Carbon Dioxide in the air, plant cells undergo photorespiration, which causes plant’s cycles to break down. To avoid this, plants have evolved two methods: CAM plants, and C4 plants. CAM plants generally live in hot, dry places.…show more content…
Cellular respiration is the opposite of photosynthesis. Cellular respiration converts organic substances, like glucose and oxygen, into carbon dioxide, ATP, and water. There are three parts to cellular respiration: Glycolysis, The Kreb Cycle, and Electron Transport Chain. Glycolysis occurs in the cytoplasm. It takes Glucose and turns it into ATP, NADH, and two Pyruvate molecules. Pyruvate diffuses into the mitochondria and makes Pyruvate Dehydrogenase Complex, which is then turned into acetyl CoA, and gives off Carbon Dioxide, and more ATP. NADH and FADH get their energy in electrons from this and send them to the electron transport chain. The Electron transport chain uses the electrons to pump Hydrogen. Once the Hydrogen builds up, ATP synthase generates more
