Chapter 13 Photosynthesis

Question 1

define chlorophyll

Answer 1

green pigment that absorbs energy light, used in photosynthesis

Question 2

define light dependent stage

Answer 2

first series of reaction in photosynthesis, it requires energy from light

Question 3

define light independent stage

Answer 3

final series of reaction in photosynthesis, it does not require light energy but it need substances produced in light dependent stage

Question 4

define photolysis

Answer 4

splitting of water, using energy from light

Question 5

define photophosphorylation

Answer 5

the production of ATP using energy from light

Question 6

Define NADP

Answer 6

a coenzyme that transfers hydrogen from one substance to another, in reaction of photosynthesis

Question 7

define Calvin cycle

Answer 7

a cycle of reaction in the light independent stage of photosynthesis in which CO2 is reduced to carbohydrate

Question 8

describe the structure of the chlorophyll

Answer 8

-surrounded by an envelope of two membrane(inner and outer)
-watery material is stroma
-the stroma contains enzymes, circular DNA, 70S ribosomes, starch grains(store carbohydrate in insoluble form), lipid droplets
