Question 1

Light dependent reactions (photophosphorylation)?

Answer 1

Takes light and convert its energy into ATP and NADPH, which gets fed into the Calvin cycle.

Question 2

Light independent reactions (Calvin Cycle)?

Answer 2

Uses ATP and NADH to synthesis organic carbon from inorganic CO2 called carbon fixation.

Question 3

Chloroplast vs mitochondria?

Answer 3

•Chloro: 3 membranes (outer, inner, and thylakoid membrane)
•Chloro: Lumen is inside the thylakoid
•Chloro: Stoma is the space between the thylakoid and inner membrane.

Question 4

!!!NADPH?

Answer 4

A high energy intermediate electron carrier and is used for anabolic reactions

Question 5

!!!Photophosphorylation proteins?

Answer 5

PS II, Cyt, Pc, PSI, PS III, NADP+ reductase

Question 6

!!!Z-Scheme?

Answer 6

Change in potential energy throughout photophosphorylation.

Question 7

!!!!!Oxidative phosphorylation vs Photophosphorylation?

Question 8

Photophosphorylation critical points?

Answer 8

•Water is used at the beginning and broken down by light. Electrons can be pulled out of it and used in ETC.
•Electrons flow through proteins and extracts potential energy to pump protons across the thy. membrane.
•Second photon of light is used to give electrons and PS I enough energy to reduce NADP+ and NADPH
•Final step: proton gradient flows through ATP synthase spontaneously and distributes energy to produce ATP from ADP.

Question 9

!!!Input and output of photophosphorylation?

Question 10

Calvin Cycle?

Answer 10

Takes the energy from photophosphorylation (ATP and NADPH), and reduces CO2 to form carbohydrates from using NADPH.

Question 11

Carbon fixation?

Answer 11

Gets carbon from the atmosphere and fixes it to a solid molecule (glucose)

Question 12

!!!Rubisco?

Answer 12

Addition of CO2 to the 5-carbon, RuBP.

Question 13

!!!Calvin cycle input output?

Question 14

Cytochrome b6f complex (cyt)?

Answer 14

A complex between PSII and PSI that transfers electrons to plastoquinol (PSII) to plastocyanin (PC) enzymes.
