Photosynthesis

what is the purpose of photosynthesis

to build carbs

where does photosynthesis occur

in the chloroplast

photautotrophs

use light energy to make organic molecules

heterotrophs

consume organic molecules from other organisms for energy and carbon

chlorophyll

green pigment; absorbs sunlight; reflects back green and yellow light;

stroma

fluid in chloroplast

thylakoid

pancake like structure (increases surface area)

grana

stacks of thylakoids

mesophyll

chloroplasts mainly found in cells of leaf

stomata

pores in leaf (co2 enters / o2 exits)

what kind of light does chlorophyll absorb + reflect

violet-blue/red light; reflect green

photosynthesis formula

6co2 + 6h2o + light → c6h12o6 + 6o2

where does light cycle take place

thylakoid

what is used and split during light cycle

h20

what is water split into during the light cycle

oxygen, two h+, two free e-

how are the electrons and hydrogen moved after being split from water during the light cycle

by the ETC

what is released by the light reaction

oxygen

main idea of light cycle

use solar energy + water to generate ATP & NADPH to provide energy for Calvin Cycle

what is the desired product of the light cycle

ATP & NADPH

what is the calvin cycle also known as

dark reaction

calvin cycle ____ require light

does not

where does calvin cycle take place

stroma

what does calvin cycle use

NADPH, ATP, CO2

what is the product of calvin cycle

G3P (to go on to make glucose, etc)
