2.9 photosynthesis Flashcards
photosynthesis
the production of carbon compounds in cells using light energy
write the photosynthesis equation
see ipad
what can the carbon compounds made from photosynthesis be used for?
for cellular respiration to produce ATP
what colors does chlorophyll absorb best?
red and blue light
what color does chlorophyll reflect best?
green light
chlorophyll
a green pigment embedded in the thylakoid membrane that is responsible for light absorption
types of chlorophyll
a and b
what happens when a chlorophyll molecule absorbs light?
it releases electrons which are used to produce ATP
draw the absorption spectrum for chlorophyll a and b
see ipad
draw the action spectrum for photosynthesis
see ipad
Rբ equation
distance moved by pigment / distance moved by solvent
2 steps of photosynthesis
- light-dependent reaction
- light-independent reaction
2 steps of photosynthesis
- light-dependent reaction
- light-independent reaction
light-dependent reaction
light energy (from the sun) is converted into chemical energy (ATP)
light-independent reaction
chemical energy (ATP) is used to synthesize carbon compounds (carbohydrates)
