photosynthesis

Front

structure of chloroplast

Back

1.) stroma - background material in chloroplast which light independent stage takes place

2.) lamellae - membranes found in the chloroplast

3.) granum - stacks of thylakoids

4.) thylakoid membrane - membrane inside chloroplast enclosing fluid filled sacs

5.) thylakoid spaces - fluid filled sacs enclosed by thylakoid membrane

has 70S ribosomes and circular DNA

definition of photosynthetic pigments

Back

coloured substances that absorbs light of particular wavelength, supplying energy to drive the reactions in the light dependent stage

Front

Definition photosystem

Back

a cluster of light harvesting pigments surrounding a reaction centre

Front

Definition reaction centre

Back

parts of photosystem towards which energy from light is funnelled

Front

parts of photosystem

Back

1.) accessory pigments (chlorophyll B, carotene, Xentophyll, etc), also have proteins

2.) reaction centre is made of 2 chlorophyll a-pigments

Front

How does the photosystem work?

Back

1.) each pigment absorbs a specific wavelength of light

2.) pigments absorbs energy from the light, channels it to the reaction centre (reaction centre is photoactivated)

Front

Difference of photosystem II and photosystem I

Back

1.) Photosystem II
- has enzyme oxygen evolving enzyme complex

• P(680), absorbs 680nm the best

• - photolysis occurs here

• 2.) Photosystem I
  - P(700), works best at 700nm

• - boosts electrons to make NADP+ into reduced NADP

Front

definition of photoactivation

Back

Emission of an electron from a molecule as a result of absorption of energy from light

Front

definition photophosphorylation

Back

producing ATP using energy which originated from light

Front

what are the two stages of photophosphorylation (just name)

Back

1.)cyclic photophosphorylation

2.) non-cyclic photophosphorylation
