Unit 2 Test pt. 2 Flashcards
Photosynthesis:
Light Reactions
1) Sunlight energy is trapped in the chlorophyll located in the chloroplasts
Energy is used to:
a) Split H2O. The O2 is released and the 2H is trapped by NADP to make NADPH2 used in Calvin Cycle (( PS 2))
b) Add a Phosphate to ADP to form ATP energy from the ATP will be used in Calvin Cycle (( PS 1))
Photosynthesis:
Calvin Cycle
1) Co2 combines with RDP 5c ( RuBP or ribulose biphosphate)
2) It becomes a very unstable 6 carbon sugar
3) It splits into two molecules of PGA (phosphoglyceraldehyde)
4) Combines with 2H from NADPH2 to form PGAL (G3P) and H20
a) PGAL can be turnedinto RDP again to continue the cycle or can be turned into glucose by combining 2PGAL molecules and a substituting H fot a phosphate
b) Water is released as water vapor through the stoma
Photosynthesis Reactants:
6 CO2 + 6 H20
Photosynthesis Products:
C6 H12 + 6 O2
Respiration:
1) Glycolysis: Anaerobic in Cytoplasm ((2 ATP))
Using 12 enzymes, each glucose is split into 2 pyruvic acids and each turns into an acetyl CoA
2) Krebs/ CAC/ TCA: Aerobic in Mitocondria ((2 ATP))
* Each Acetyl CoA goes through a series of reactions to produce 12 NADH2 and the waste, 6 CO2.*
3) Electron Transport Chain: Aerobic in Mitocondria ((around 32 ATP))
A chai of reactions where enzymes break down the 12 NADH2, losing ATP but regaining for a total of 32 and H2O
Chemosynthesis:
The process used in hydrothermal vemts when there is not enough sunlight present, done by chemosynthetic bacteria
Chemosynthesis Reactants:
6 CO2 + 6 H2O + 3 H2S ( Hydrogen Sulfide)
Chemosynthesis products:
C6 H12 O2 + 3 H2SO4 ( Sulfuric Acid)
Respiration Products:
6 CO2 + 6 H2O + 36 ATP
Fermentation: In Humans
when the tissue requires energy at a faster rate than oxygen can be supplied, the 3C Pyruvic Acids are turned into lactic Acid.
* Make your muscles sore
Fermentation: Other examples
- Causes dough to rise
- Makes alcoholic beverages
- Found in yogurt and cheese
Respiration Reactants
Oxygen (6 O2) + Glucose (C6 H12 O6)
