Chapter 10

Question 1

Electromagnetic spectrum

Answer 1

Range of electromagnetic energy/ radiation (light) visible and invisable

Question 2

Wavelength

Answer 2

Distance between peaks

Question 3

Photosynthesis

Answer 3

Endergonic reaction
Anabolic reaction converts solar to chemical energy

Question 4

Photosystem

Answer 4

Specialized sections within a thylakoid sac membrane

Question 5

Photosystem II

Answer 5

Functions first and is the best at absorbing a wavelength of P680

Question 6

Photo system I

Answer 6

Best at absorbing a wavelength of P700

Question 7

Dark Cycle/ Calvin Cycle

Answer 7

Anabolic process—Endergonic
Build complex carbs from smaller molecules by using ATP and reducing electron power

3 phases
carbon fixation
Reduction
Regeneration

Question 8

Calvin cycle- Carbon Fixation

Answer 8

Carbon dioxide incorporated into a 5 carbon intermediate —-ribulose biphosphate (RuBP)/ rubisco
Unstable 6 carbon intermediate splits in half

Question 9

Calvin Cycle- Reduction

Answer 9

Each molecule of the 3 carbon sugar is phosphoruylated by ATP NADPH donates electron and phosphate— g3P

Question 10

Calvin Cycle- Regeneration

Answer 10

Last step of the Calvin cycle 5 of the 3 carbon G3P are rearrange into 3 molecules of RuBP

Has to spend 3 ATP to prepare for the next molecule carbon dioxide

To produce 1 molecule for G3P , 9 molecules of ATP and 6 molecules of NADPH rom light cycle must be spent—

G3P can be used for carbon skeleton
