Photosynthesis and transpiration

Question 1

Formula of Photosynthesis

Answer 1

CO2 + H2O + light -> CH2O + O2

Question 2

Formula of respiration

Answer 2

C6H12O6 + 6O2 -> 6CO2 + 6H2O + 36 ATP

Question 3

light dependent reaction site

Answer 3

thylakoid

Question 4

light dependent reaction process

Answer 4

light -> Photosystem II -> Pq -> Cytochrome complex -> Pc and light -> Photosystem I -> Pd -> NADP+ reductase -> NADPH ——-> Calvin Cycle

Question 5

Calvin Cycle process

Answer 5

3CO2 -> Phase 1: Carbon fixation -> Phase 2: Reduction -> G3P (product) -> Phase 3: Regeneration of RuBP -> Rubisco -> back to Phase 1

Question 6

CAM photosynthesis process

Answer 6

plants opens stomata at night to collect CO2 and chemically store it

then use the CO2 the next day without opening the stomata for photosynthesis

Question 7

Photorespiration

Answer 7

O2 substitutes CO2 in rubisco

reduced photosynthetic rate

Question 8

C4 plants process

Answer 8

CO2 -> 3C (PEP) -> 4C (C4) organic acid -> Calvin Cycle

minimizes the cost of photorespiration

Question 9

Glycolysis occurs in

Answer 9

Cytosol

Question 10

Krebs cycle occurs in

Answer 10

mitochondrion (matrix)

Question 11

Chemiosmosis occurs in

Answer 11

mitochondria (inner membrane)

Question 12

Glycolysis products

Answer 12

Glucose -> 2 pyruvate
2 ATP—————> 2 ATP
2 NADH

Question 13

Krebs cycle products

Answer 13

2 pyruvate -> 6CO2 ———>6CO2
2 ATP————————> 2 ATP
8 NADH
2 FADH2

Question 14

Chemiosmosis products

Answer 14

2 NADH (Glycolysis) * 2 ATP —–> 4 ATP
8 NADH (Krebs) * 3 ATP ———–> 24 ATP
2 FADH2 (Krebs) * 2 ATP ———-> 4 ATP

12H + 6O2 --> 6H2O -------> 6H2O

Question 15

Total ATP product of respiration

Answer 15

36 - 38 ATP
