4 photosynthesis, cellular respiration and biotechnological applications

Question 1

understand that specific enzymes are needed to catalyse each reaction during photosynthesis and cellular respiration

Question 2

know what NADP+ and ADP do in photosynthesis

Question 3

know what ADP, FAD and NAD+ do in cellular respiration (later)

Question 4

state what happens to coenzymes once they have delivered their energy or H+

Question 5

list the loaded and unloaded forms of NADP+, ADP, NAD and FAD (later)

Question 6

state the inputs and outputs of the light dependant stage

Question 7

state the inputs and outputs of the light-independent stage

Question 8

state the location within a chloroplast (granum, stroma) where each stage occurs

Question 9

state the role of Rubisco

Question 10

explain the issues faced by C4 and CAM plants (desert and tropical plants)

Question 11

describe the conditions in which rubisco is more likely to bind to O2 than CO2

Question 12

describe photorespiration and when it occurs

Question 13

state how C4 plants have adapted to avoid photorespiration

Question 14

explain why PEP carboxylase can avoid photorespiration

Question 15

state how CAM plants have adapted to avoid photorespiration

Question 16

explain the importance of maximising photosynthetic efficiency

Question 17

define ‘limiting factor’ in chemical reactions

Question 18

explain how light availability can affect the rate of photosynthesis

Question 19

explain how water availability can affect the rate of photosynthesis

Question 20

explain how CO2 concentration can affect the rate of photosynthesis

Question 21

explain why temperature affects the rate of photosynthesis
