Chapter 10: Photosynthesis Flashcards
Stomata
openings in the leaf that allow for the exchange of gases
Guard cells
open and close stomata openings
Photosynthetic pigments
pigments found in chlorophyll absorb various portions of visible light; absorption spectrum
Absorption spectrum
spectophotometer measures the amount of light that passes through a sample of pigments
Action spectrum
measures the rate of photosynthesis at different wavelengths of light measured by the rate of oxygen produced
Photosynthesis formula
6CO2 + 6H2O → C6H12O6 + 6O2
Light reactions
take place when there is light present in the thylakoid
Calvin cycle (dark reactions)
take place in stroma, occur in light or dark, reshuffling of carbons using NADPH and ATP as energy
Stroma
open space in the chloroplast
Thylakoid
green disks found in a stack (granum)
photosystem 1
Makes NADPH (part of LR)
photosystem 2
Makes ATP (part of LR)
Electron Transport Chain
electron receptors from photosystem 2 pass H2O through to create ATP
NADP reductase
reaction from photosystem 1 and 2 go through to create NADPH
Chemiosmosis
the process of making ATP in LR
