CH8 Continuation

Question 1

Cellular Respiration Equation

Answer 1

C6 H12 O6 + 6 O2 –> 6 CO2 + 6 H2O + ATP

Question 2

2 major pathways in the breakdown of pyruvate

Answer 2

1. Respiration
2. Fermentation

Question 3

2 types of respiration and differences in terms of:

-terminal e acceptor
-main process

Answer 3

Aerobic:
-O2
-pyruvic acid is completely oxidized to CO2
via the TCA

Anaerobic:
-nitrates, sulfates, carbonates
-employed by methanogens (strict anaerobes)
and denitrifiers (facultative anaerobes)

Question 4

3rd step of cellular respiration (2 phases)

Answer 4

1. Oxidative Phosphorylation
2. Electron Transport Chain

Question 5

3 steps in Oxidative Phosphorylation

Answer 5

1. ATP production via chemiosmosis

3. Proton Motive Force (proton gradient)

Question 6

an energized state of a membrane created
by expulsion of protons

Answer 6

Proton Motive Forces

Question 7

What is the electron transport chain

Answer 7

series of carrier molecules that are oxidized and
reduced as electrons are passed down the chain

Question 8

How many ATP per NADH and FADH2

Answer 8

NADH - 2.5
FADH2 - 1.5

Question 9

Central Metabolism Location of eukaryotes and prokaryotes in:

3. Krebs Cycle

Answer 9

ATP ; NADH ; FADH2

G: 2, 2, 0
IS: 0, 2, 0
KC: 2, 6, 2

Question 10

Question 11

How many in total ATPs are produced in EUKARYOTES and PROKARYOTES

Answer 11

36 and 38

Question 12

2 types of fermentation

Answer 12

1. Alcoholic fermentation
2. Lactic Acid fermentation

Question 13

Which step from the cellular respiration does FERMENTATION only have

Answer 13

glycolysis

Question 14

Process of Alcoholic Fermentation

Answer 14

Glycolysis -> 2 pyruvate -> 2 CO2 & 2 acetaldehyde -> 2 -> ethanol

Question 15

Process of Lactic Acid Fermentation

Answer 15

Glycolysis -> 2 pyruvate -> 2 lactate

Question 16

Does fermentation have external e-acceptors?

Answer 16

No, they use organic compounds like 2 pyruvate and 2 acetaldehyde

Question 17

Pigment responsible for color of plants

Answer 17

Chlorophyll

Question 18

2 phases of Photosynthesis

Answer 18

Light dependent and Calvin Cycle

Question 19

Where does Light dependent reaction occur

Answer 19

Thylakoids

Question 20

Process in Light Dependent reactions and PRODUCTS

Answer 20

H2O + Light -> ATP, NADPH, and Oxygen

H2O is split. H from water is transferred to NADPH

Question 21

Which of the products of light dependent is needed for calvin cycle

Answer 21

ATP and NADPH

Question 22

Where does calvin cycle reaction occur

Answer 22

stroma

Question 23

Process in Calvin Cycle and PRODUCTS

Answer 23

CO2 + ATP + NADPH -> Glucose

Question 24

• occurs in presence of?
• type of phase
• location of photolysis

Answer 24

LR:
- light
- photochemical phase
- PS-II

DR:
- absence of light
- biochemical phase
- does not occur
