Unit C Photosynthesis and Cellular Respiration

Question 1

Chloroplasts

Answer 1

responsible for photosynthesis

Question 2

Granum

Answer 2

a stack of thylakoid

Question 3

Thylakoid

Answer 3

contain chlorophyll (fill the thylakoid) - where the light dependant reactions occur

Question 4

Lumen

Answer 4

inside of thylakoid

Question 5

Stroma

Answer 5

empty space inside of chloroplast - where the calvin cycle occurs

Question 6

Rf value

Answer 6

pigment distance/solvent front distance

Question 7

Photosystem II

Answer 7

uses light to convert H20 into O2, H+ ions and high energy electrons

Question 8

Cytochrome Complex

Answer 8

uses energy from electrons to pump H+ ions into the lumen

Question 9

Photosystem I

Answer 9

reenergizes electron using light

Question 10

Ferrodoxin

Answer 10

carries electrons from PSI to NADP+ reductase

Question 11

NADP+ Reductase

Answer 11

uses energy to convert NADP+ and 2H+ into NADPH and H+

Question 12

ATP Synthase

Answer 12

Uses the concentration gradient to convert ADP and P into ATP

Question 13

Calvin Cycle

Answer 13

Carbon Fixation: CO2 + RuBP with Rubisco = 3-PGA
Reduction: 3-PGA + ATP and NADPH = G3P
Some G3P = Glucose
Regeneration: G3P + ATP = RuBP

Question 14

Mitochondria

Answer 14

site of cellular respiration

Question 15

Glycolysis

Answer 15

occurs in cytoplasm - converts glucose into 2 pyruvate + 2 ATP

Question 16

Anaerobic Cellular Respiration

Answer 16

produce end products such as ethanol, CO2 or lactic acid

Question 17

Inbetween Step

Answer 17

pyruvate + Coenzyme A = Acetyl-CoA

Question 18

Kreb’s Cycle

Answer 18

1. Acetyl CoA + 4C = Citrate (6C)
2. Citrate = 4C + 2NADH + 2 CO2
3. 4C produces ATP + NADH + FADH2

Question 19

Oxidative Phosphorylation

Answer 19

1. electron carriers (NADH FADH2) drop electrons
2. (ETC) Electrons lose energy (staircase) and from 32-34 ATP
3. Electrons + O2 = H2O

Question 20

Electron Transport Chain

Answer 20

electrons pump H+ from matrix into the inner membrane space
