Similarities between Photosynthesis and Cellular Respiration
- electron transport chain is used for transferring electrons and other stuff between reactions
- ATP is used in both systems
- chemiosmosis allows ATP synthesis to make more ATP molecules
Differences between Photosynthesis and Cellular Respiration
- Photosynthesis uses Carbon Dioxide and Hydrogen to create Glucose and Oxygen
- Cellular Respiration uses Oxygen and Glycogen to create Carbon Dioxide and Hydrogen
- NADPH is needed in photosynthesis
- Formula for photosynthesis = C6O2------>C6H12O6+6O2
- Formula for Cellular Respiration = 6O2 +C6H12O6 ------> 6CO2 +6H2O
C3 Plants:
- normal plants the doesn't have to face harsh environment
- only opens their stomata during the day time
- regulates the Light reaction and Calvin Cycle normally
C4 Plants:
- has 2 different cells that C3 plants and CAM doesn't have: Mesophyll Cells and bundle sheath cells
- the plant uses C4 carbon fixation in which carbon is attached to the phophoenolpyruvic in the Mesophyll Cell ceating a four carbon compound
- then in the bundle sheath the four carbons is then decomposed into carbon and pyruvate and to be used for the C3 pathway
- the carbon in the C3 pathway is turned into glucose and the pyruvate is sent back into the Mesophyll cell
- afterward the pyruvate is turned back into a phophoenolpyruvate with the help of the ATP.
CAM Plants:
- They only have one cell
- their stomata is only open during the night, closed during the day (opposite of the C3 plants)
- Carbon inhaled by the plant and oxygen is exhailed
- they usually have the characteristics of small and has small or thin leaves to store water, these plants are most likely found in the destert and any other harsh biomes.
