Cellular Respiration/Photosynthesis
Maddie Muenster 6/7A
Photosynthesis!
- Plant Cells have molecules that absorb light energy.
- Molecules are called pigments.
- Chlorophyll is found in chloroplasts
- Chlorophyll (main pigment) gives plant green color.
- Uses energy captured from chlorophyll to change carbon dioxide into food.
- Sugar glucose is a carbohydrate. (found in photosynthesis.
Cellular Respration!
- Respiration Means breathing but Cellular respiration is different.
- During CR food is broken down into H2O or CO2 and energy is released.
- ATP supplies energy that fuels the activity.
- Takes place in the cell membrane.
Products and Reactants
Products and Reactants are what enters and leaves the cell.
Photosynthesis
Enters- Water and CO2
Leaves- Glucose sugar and H2O
Cellular Respiration
Enters- H2O and Glucose Sugar
Leaves- ATP, Carbon dioxide, and water
Diffrences!
- Photo. takes place in chloroplasts when CR takes place in Mitochondria.
- Photo. takes place in sun light when CR takes place all the time
- CO2 and H2O enters for photo. when Glucose and Oxygen enters for CR
- Glucose and Oxygen leaves for Photo. and CO2 and H2O leaves for CR
- Energy sources for Photo. is light and CR is Chemical bonds.
Similarities!
- ATP is a key molecule in each
- Mitochondria of cell respiration and chloroplasts of photosynthesis have distinct similarities
- Both use chemiosmosis to generate ATP
- Both rely on movement of electrons for operation
- Both use electron transport chains in production of ATP
