LESSON 9 part 2

Question 1

Loss of electron, Gain of Oxygen, Loss of Hydrogen

Answer 1

Oxidation

Question 2

Gain of electron, Loss of Oxygen, Gain of Hydrogen

Answer 2

Reduction

Question 3

equation of Photosynthesis in a nutshell

Answer 3

6 CO2+12 H2O+light energy -> C6H12O6 + 6 O2

Question 4

the 2 main stages in Photosynthesis

Answer 4

Light-Dependent reactions
Calvin Cycle (light-independent reactions)

Question 5

Occurs in the Thylakoid membrane and produces ATP and NADPH

Answer 5

Light Dependent Reaction

Question 6

Primarily occurs in Stroma and produces glucose

Answer 6

Calvin Cycle

Question 7

Light Dependent reactions involves

Answer 7

Photosystem II, Electron transport chains (ETC), Photosytem I, and ATP synthase

Question 8

Episode 1 & 2: Light Harvesting
(Occurs in

Answer 8

Photosystem II

Question 9

Light - Harvesting complex (LHC) contains

Answer 9

Chlorophyll a&b and Carotenoids

Question 10

Light strikes LHC and energy is absorbed and transferred through different chlorophyll pigments until it reaches a special chlorphyll a pair, P680, where

Answer 10

it releases 2 electron

Question 11

Photons will strike enzymes that will cleave water to produce

Answer 11

2 hydrogen atoms, an oxygen atom and 2 e-
H20 -> 2H+ + 1/2 O2 + 2 e-

Question 12

how many molecules of water is needed to produce 1 molecule of oxygen gas (O2)

Answer 12

2 molecules water

Question 13

give the summary of ep 1 and 2

Answer 13

Light harvesting produces oxygen as by-product, electrons are released (ep 1) and regenerated (ep 2), 4 H+ in thylakoid

Question 14

The 2 e- released by P680 is carried by an

Answer 14

electron carrier protein

Question 15

NADPH is needed for the

Answer 15

Calvin Cycle

Question 16

At the end of the ETC, the electrons activate an enzyme which reduces an

Answer 16

oxidized Nicotinamide adenine dinucleotide phosphate (NADP+) into NADPH

Question 17

By the end of episode 5, there are

Answer 17

8 H+ entered into the Thylakoid

Question 18

3 phase of Calvin Cycle

Answer 18

Carbon Fixation Reduction Regeneration
