Photosynthesis

Question 1

Photosynthesis occurs in

Answer 1

plants only

Question 2

whats photosynthesis

Answer 2

process by which plants and other photosynthetic organisms trap the sun’s energy and transform it into energy rich chemicals

Question 3

whi does cellular respiration

Answer 3

all plants n animals

Question 4

whats cellular respiration

Answer 4

process by which cells break down high energy compounds and generate ATP

Question 5

whats ATP

Answer 5

battery, the direct source of energy for organisms

Question 6

photosynthesis takes what in to produce ____ and ____

Answer 6

carbon dioxide, water and light energy to produce glucose and oxygen

Question 7

photosynthesis is an example of a ___ pathway

Answer 7

anabolic

Question 8

what anabolic pathway

Answer 8

to make larger molecules from simpler ones

Question 9

cellular respiration takes in what to produce ____ and ___ and release ___

Answer 9

glucose and oxygen to produce carbon dioxide and water and release energy

Question 10

cellular respiration is an ____ pathway

Answer 10

catabolic

Question 11

whats catabolic pathway

Answer 11

breaking down larger molecules into smaller ones

Question 12

key difference between photosynthesis and cellular respiration

Answer 12

the type of energy they use
photosynthesis- light
CR- Releases ATP

Question 13

whats Leo says ger

Answer 13

Leo- lose electrons= oxidation
ger- gain electrons = reduction

Question 14

photosynthesis bio 20 definition

Answer 14

energy from sunlight is stored in bonds of glucose

Question 15

in photosynthesis what is stored glucose used for

Answer 15

converting into structural molecule cellulose

Question 16

whats a chloroplast

Answer 16

cell organelles

Question 17

whats chlorophyll

Answer 17

molecules that trap solar energy and give green colour of plant

Question 18

where are chlorophyll located and bound to

Answer 18

inside chloroplasts bound to thylakoid membranes

Question 19

whats stroma

Answer 19

inner solution of chloroplast

Question 20

whats a chloroplast made up of

Answer 20

inner and outer membranes

Question 21

what are thylakoids

Answer 21

flattened sacs in a chloroplast

Question 22

whats a grana

Answer 22

stacks of thylakoids

Question 23

what are stack of thylakoids called

Answer 23

grana

Question 24

what are the flattened sac in chloroplast called

Answer 24

thylakoids

Question 25

the two types of metabolic pathway are

Answer 25

light dependent reaction and light independent reaction (dark reaction)

Question 26

which metabolic reaction occurs when light is present

Answer 26

light dependent

Question 27

whats a light dependent reaction

Answer 27

reaction that traps solar energy to make high energy compounds (NADPH) - battery like ATP less useful

Question 28

whats a light independent reaction

Answer 28

the energy of ATP and reducing power of NADPH are used ti reduce CO2 and make glucose which can be converted to starch for storage

Question 29

formula for light reaction

Answer 29

6 CO2+6 H2O +light energy=C6H12O6+6 O2

Question 30

light independent reaction formula

Answer 30

C6H12O6+6O2= 6CO2+6H2O+ Energy

Question 31

in Light dependent reaction where is solar energy trapped

Answer 31

in pigment found in thylakoids membrane of chloroplast

Question 32

2 main types of pigments found innleaves

Answer 32

chlorophyll a- main photosynthesis pigment chlorophyll b-

Question 33

chlorophyll a and b absorb what and reflect what

Answer 33

absorb everything but green reflect green which gives leaves tge green apperance

Question 34

other pigments found in leaves

Answer 34

B carotene

Question 35

what pigments dise carotene B absorb and reflect

Answer 35

absorb blue green , reflect orange and red

Question 36

what dose B carotene get converted to and used for

Answer 36

vitamin A made into Retinal the visual pigment in our eyes

Question 37

in fall leaves what dosecthe chlorophyll do

Answer 37

masks other pigments in spring / summer months

Question 38

what happens during fall /winter to leaves

Answer 38

cooler temperatures stop chlorophyll production revealing the other carotenoid pigments

Question 39

why are there multiple types of pigments

Answer 39

sii ok that the leaf can absorb more pigment by hsving more colours present

Question 40

C6H12O12 CHO takes ___ energy but also ___ alot of energy when ____

Answer 40

takes alot of energy but also provides alot of energy when broken down

Question 41

oxidation is

Answer 41

losing electrons

Question 42

reduction is

Answer 42

gaining electrons

Question 43

do compounds contain more energy in oxidizing or reduction form

Answer 43

reduction because there gaining electrons

Question 44

whats accomplished by photosynthesis

Answer 44

energy stored in glucose

Question 45

what is a pigment
