Lecture 9 Photosynthesis II

Question 1

Light independent reactions=

Answer 1

calvin cycle

Question 2

where does the calvin cycle take place

Answer 2

stroma of the chloroplast

Question 3

what does the calvin cycle do

Answer 3

series of reactions to generate organic carbon from inorganic carbon

Question 4

3 phases of calvin cycle

Answer 4

carbon fixation
reduction
regeneration

Question 5

Carbon fixation

Answer 5

3 CO2s attach to 3 rubiscos, then the 3 6carbon structures split into 3 carbon structures giving 12 total

Question 6

Rubisco

Answer 6

probably most abundant protein on earth, 5 carbons 1-5 biphosphate

Question 7

Reduction

Answer 7

1. Energy and phosphate added from ATP hydrolysis ( 6 ATP phosphorize the 6x P-C-C-C-P )
2. high energy electrons are donated ( C-C-C-P ) creating G3P
3. one of the G3Ps is a direct product, the rest continue to regeneration

Question 8

Water is…
CO2 is…

Answer 8

oxidized
reduced
