Lab 6 Flashcards
thylakoid function in photosynthesis
contains light harvesting pigments, e- transport chain
stroma function in photosynthesis
contains enzymes for calvin cycle (rubisco)
thylakoid lumen function in photosynthesis
moving H+ in forms proton gradient
H+ out forms ATP by ATP synthase
reactants and products of respiration
reactants: sugar and O2
products: CO2 and H2O
reactants and products of photosynthesis
reactants: CO2 and H2O
products: sugars and O2
coleus leaf experiment findings
starch production in areas with green pigment (chlorophyll)
chlorophyll present in chloroplasts, absorbs light energy for photosynthesis
what colors/wavelengths does chlorophyll a absorb?
red (approx 600 nm) and blue (approx 400 nm)
TLC experiment findings
most hydrophobic pigments travel farthest
accessory pigments function
collect light energy, transfer chlorophyll a at reaction center
green seedlings TLC colors
orange, green, and yellow pigments
chlorophyll a and b
yellow seedlings TLC colors
yellow, sometimes orange pigments
