Chapter 7 Test

Question 1

Oxidation Vs Reduction

Answer 1

Oxidation is loss of electrons
Reduction is gain of electrons

Question 2

Photosynthesis

Answer 2

uses Solar Energy
Makes Carbohydrates and organic molecules from Co2
Makes ATP for the cell

Question 3

Mitochondria

Answer 3

Makes ATP for the Cell

Question 4

Stomata

Answer 4

a slit in the epidermis of the leaf that lets gasses in and out

Question 5

Thylakoids

Answer 5

disks in the chloroplast that are covered in chlorophyll

Question 6

Chlorophyll a

Answer 6

432-662 nm

Question 7

Chlorophyll b

Answer 7

460 -642 nM

Question 8

Carotenoids

Answer 8

funnel energy to chlorophyl

they absorb the blue-green spectrum and funnel this to clorophyll

Question 9

Phycobilins

Answer 9

cyanobachteria
Present in red seaweed
similar to caratenoids

Question 10

Protective chemicals

Answer 10

Xanthophyl and Antocyanin

Question 11

Photosystem II
(Remember this is II)

Answer 11

Electron acceptor catches and sends electrons
Energy from photons——->Electrons
takes place in Porhyren rings
(a) where chlorophyll absorbs light energy
(b) light sensitive

Question 12

How are electrons Replaced?

Answer 12

H2O breakdown by Plastoquinone Pq and enzyme complex
2H2O—>4H+ +O2 + 4 e-

Question 13

Electron transport chain ETC 1

Answer 13

Electrons go to Pq from there it goes to Cytochromes

Question 14

Cytochromes CYT

Answer 14

Receives electrons from Pq
Pumps H+ protons from Stroma to Thylakoid space: powered by Electron movement

Question 15

Plastocyanin

Answer 15

Sends E- to Photosystem I

Question 16

Photosystem I

Answer 16

Same: Light energy transfered to electrons
Different: PS1 sends electrons to Feridoxin

Question 17

Feridoxin FD

Answer 17

decides if there is enough ATP
If there is not enough: FD sends electrons back to Cyt to make more H+
If enough sent to NADP+ reductase

Question 18

NADP+ Reductase

Answer 18

Reduces NADP+
Adds charged electrons to NADP+ which makes NADPH
this goes to the Calvin cycle

Question 19

ATP synthesis

Answer 19

Generates ATP from H+ movement from thylakoid space into stroma
Clamps Pi (Phosphate) to ADP

Question 20

ATP

Answer 20

Adenosine Triphosphate

Question 21

Inputs to Calvin Cycle

Answer 21

Co2 (Carbon)
ATP (Stored Energy)
NADPH (Electrons)
