SAC 1 b) photosynthesis

Question 1

what is photosynthesis

Answer 1

the process in which light energy is converted to chemical energy stored in sugars (glucose).

Question 2

equation for photosynthesis

Answer 2

12H20 + 6C02 -> (light + chlorophyll) -> 602 + C6H1206 + 6H20

Question 3

what is a biochemical pathway

Answer 3

a series of enzyme-catalysed reactions where the product of one reaction becomes the substrate/reactant in the next reaction.

Question 4

what is a C3 plant

Answer 4

majority of plant species on earth **

Question 5

When does C3 plant photosynthesis reaction occur?

Answer 5

during the day, in the chloroplasts which contain chlorophyll

Question 6

main purpose of photosynthesis and which organisms carry it out

Question 7

Know the chloroplast structure that relates to its function – grana, thylakoid membrane, stroma.

Question 8

structure of a leaf

Question 9

How are the requirements for photosynthesis supplied to the leaf?

Question 10

What are the functions of palisade cells and spongy cells?

Question 11

functions of xylem and phloem (in veins)

Question 12

functions of stomata and guard cells

Question 13

functions of air spaces and waxy cuticle

Question 14

functions of upper and lower epidermis

Question 15

inputs/ outputs of light-dependent stage

Question 16

inputs/outputs of light-independent stage (calvin cycle)

Question 17

location of both stages of photosynthesis

Question 18

what are coenzymes

Question 19

coenzymes cycling through the two stages of photosynthesis

Answer 19

NADPH and ATP

Question 20

what is rubisco

Question 21

role of Rubisco in the light independent stage

Question 22

What is photorespiration and why is it detrimental to a plant?

Question 23

what is a C4 plant

structural adaptations of a C4 plant

Question 25

what is CAM

Question 26

explain the process of CAM photosynthesis and why it is important for the plant's survival

Question 27

explain process of C4 photosynthesis and why it is important for the plant's survival

how the rate of photosynthesis may be affected by CO2 concentration

Question 31

how the rate of photosynthesis may be affected by temperature

Question 32

how the rate of photosynthesis may be affected by pH

Question 33

link between enzymes and the rate of photosynthesis
