on the wild side

Question 1

photosynthesis involves reduction of

Answer 1

carbondioxide to carbohydrate

Question 2

carbohydrates can be used to provide energy for

Answer 2

respiration

Question 3

hydrogen for respiration comes from

Answer 3

splitting of the water by light

Question 4

waste oxygen is released to

Answer 4

atmosphere

Question 5

6CO2 + 6H20

Answer 5

C6H12O6 + 6O2

Question 6

Splitting of water by light is called

Answer 6

photolysis

Question 7

the energy for photolysis is trapped by

Answer 7

pigment called photolysis

Question 8

energy for photolysis is

Answer 8

trapped by a pigment called photolysis

Question 9

light dependent reactions

Answer 9

in this process, a pair of electrons from chlorophyll is boosted to a higher energy level by the light energy it has trapped.Here they are accepted by an electron acceptor and then passed along a chain of carriers.energy released is used to convert adp and inorganic phosphate.the electrons then enter another chlorophyll molecule.the electrons then enter another chlorophyll molecule.the electron then enter another chlorophyll molecule,The electron eventually passes to NADP wuth the hydrogen from whater to form reduced NADP.The ATP and reduced NADP are then used in light dependent reactions to make carbohydrate from carbondioxide.
occurs in thylakoid

Question 10

the light dependent reactions make

Answer 10

ATP and Reduced NADP which are then used in the light dependent reactions

Question 11

another name for light independent

Answer 11

calvin cycle

Question 12

5 C molecules Rubp combines with co2

catalyzed by

Answer 12

unstable 6 carbon compound

RUBISCO

Question 13

6 C compound immediately splits into

Answer 13

2 molecules of 3 C compound called Gp

Question 14

gets energy from

Answer 14

Atp converted to adp and phosphate and reduced NADPH

Question 15

reduced nadp and atp coverts GP to

Answer 15

GALP

Question 16

galp goes in series and

Answer 16

either becomes RuBp or some will change into glucose

Question 17

co2 is fixated in

Answer 17

calvin cycle

Question 18

ATP provides energy for

Answer 18

chemical reaction in cell

Question 19

when energy is needed

Answer 19

,phosphate is removed from atp to give adp and phosphate

Question 20

the energy is released when

Answer 20

phosphate forms bonds with water

Question 21

ATP is also used widely as

Answer 21

a way of transferring energy

Question 22

ATP is an intermdeiate between

Answer 22

energy producing reaction and those that need energy

Question 23

some of the glucose made in calvin cycle

Answer 23

is used by the plant in respiration.the rest is used to synthesise all the molecules on which the plant relies

Question 24

molecules on which the plant relies

Answer 24

simple sugar
polysacharide
amino acid
lipid
nucleic acid

Question 25

glucose from calvin cycle is

Answer 25

used in resp to produce co2,h20 and energy
nucleic acids (DNA & RNA)
in amino acid to make proteins

Question 26

thylakoid cookies

Answer 26

has chlorophyll to absorb sunlight and convert to atp

Question 27

chloroplast is —- memb

Answer 27

double

Question 28

empty space

Answer 28

stroma

has chlorophyll to absorb sunlight and convert to atp

Question 29

NPP=

Answer 29

GPP-R

Question 30

in any habitat a species niche determined by

Answer 30

biotic and abiotic factors

Question 31

pioneer species

Answer 31

primary sucessions happens when an area that is devoid of life is first colornised by lichen and algae on bare rock that can cope in harsh conditions these are called pioneer species.

Question 32

pioneer species alter the envt in a way that

Answer 32

makes it an unsuitable home for them but suitable for new species to establish.the new species often replace the existing species

Question 33

a similar process occurs again

Answer 33

through stages known as seres until a stable community is reached.in stable woodland,for example trees die but new ones of same species grow to fill the gap.this is a climax community if the sucession starts with living things already present for example if grazing stopped in a meadow which then became woodland this is secondary sucession.
