1
Photosynthesis and Cellular Respiration
2
Photosynthesis What is it? In what type of cells does it occur?
Energy in sunlight transferred to food(carbohydrate) In what type of cells does it occur? Plant Cells (all organisms that are photosynthetic) Where in the cell does it happen? Chloroplast
3
Inside a Chloroplast Thylakoid – Where the chlorophyll is located.
Stacks of Thylakoids form Grana (Granum - 1) Where Light-Dependent Reactions happen. LDR – Needs Light and Water LDR – Gives off oxygen
4
Inside the Chloroplast
Stroma – The region outside the Thylakoid membranes. Where the Calvin Cycle takes place. Calvin Cycle – Light – INdependent Reaction Calvin Cycle – Gives off Sugars
5
Carbon Dioxide + Water Sugar + Oxygen
PHOTOSYNTHESIS Consists of both the light-dependent and light-INdependent reactions. 6CO2 + 6H2O C6H12O6 + 6O2 Carbon Dioxide + Water Sugar + Oxygen

7
Cellular Respiration Food(carbohydrate) must be converted to a useful form of energy that the cell can use. That useful form is ATP (adenosine triphosphate) Cellular Respiration is the chemical process that makes ATP for cell energy needs
8
Cellular Respiration Involves 3 steps
Glycolysis – Happens in the cytoplasm Kreb’s Cycle – Happens in the Mitochondrion Electron Transport Chain – Also happens in the Mitochondrion
9
Cellular Respiration Chemical equation for cellular respiration:
C6H12O6 + 6O2 6CO2 + 6H2O Sugar + Oxygen Carbon Dioxide + Water
10
Photosynthesis/Cellular Respiration
Captures Energy (Sun) Happens in: Chloroplast Only Plants Cellular Respiration Releases Energy (Food) Happens in: Mitochondria Most living things, including plants.
11
Comparison Photosynthesis 6CO2 + 6H2O C6H12O6 + 6O2
Carbon Dioxide + Water Sugar + Oxygen (Energy IN) Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O Sugar + Oxygen Carbon Dioxide + Water (Energy OUT)
12
ATP Where does the transfer of energy to ATP take place in a cell?
Mitochondria Do plant and animal cells have Mitochondria? Yes
