Autotrophs
Producers (Produce their own food) - Plants (& some protists and prokaryotes) TERM 2
Photoautotrophs
DEFINITION 2 Use light as a source of energyy to synthesize organic substances TERM 3
Heterotrophs
DEFINITION 3 Consumers - Feed on autotrophs or other heterotrophs TERM 4
Cellular Respiration - Reaction Type -
Byproducts - Products - Electron Carrier
DEFINITION 4
- Exergonic (Redox) - CO2 & H2O - ATP - NADH TERM 5
Photosynthesis - Reaction Type - Byproducts -
Electron Carrier
DEFINITION 5
- Endergonic (Redox) - O2 & H2O - NADPH
Light Reactions
- Occur in thylakoids - Produce NADPH & ATP - Occur in Photosystems (II & I) TERM 7
Calvin Cycle
DEFINITION 7
- Occur in Stroma - Produce sugar TERM 8
Sunlight (wavelength vs. energy)
DEFINITION 8 Shorter wavelength -----> Longer wavelength Higher energy - ---------> Lower energy TERM 9
Photons
DEFINITION 9 One "particle" or light TERM 10
Chlorophyll a
DEFINITION 10 (Pigment) Participates directly in light reaction
Calvin Cycle (3 steps)
- Carbon Fixation (by rubsico) RuBP + CO2 - Reduction G3P - Regeneration RuBP re-formed - Cost: 13 GP = 3CO2 + 9ATP
Photorespiration
DEFINITION 17 (Detrimental to plans) - C3 plans use CO2 to make sugar when there is water loss, te stamina closes, but it then cannot get CO2 - Rubsico can fix O2 --> CO2 - Can waste up to 50% of fized C - May be photoprotective TERM 18
Rubsico
DEFINITION 18 Can fiz O2 --> CO2 - Uses ingredients with no gains (wastes energy & carbon)
