Photosynthesis

Question 1

ATP

Answer 1

a molecule that transfers energy from the breakdown of food molecules to cell processes.

Question 2

ADP

Answer 2

A low energy molecule that can be converted to ATP by the addition of a phosphate group.

Question 3

function of leaves

Answer 3

harvesting energy from the sun.

Question 4

What drives photosynthesis

Answer 4

light drives photosynthesis; the most important chemical reaction on Earth.

Question 5

photosynthesis is a complex series of more than how many reactions?

Answer 5

more than 50 reactions.

Question 6

how is it done

Answer 6

plants take in energy from the sun; water Is taken through the roots.

Question 7

how Is it done

Answer 7

plants convert light into chemical energy in the bonds of glucose and produce O2 as a waste product.

Question 8

glucose formula

Answer 8

C6 ll12 O6

Question 9

how can photosynthesis be summarized

Answer 9

6co2+6h2o= c6h12o6+6o2

Question 10

Mesophyll

Answer 10

the tissue in the interior of the leaf where chloroplasts are concentrated.

Question 11

Stomata

Answer 11

microscopic pores in the surface of the leaf(co2 enters, o2 exits).

Question 12

thylakoids

Answer 12

sac-like photosynthetic membranes; think of life saver candy.

Question 13

grana

Answer 13

stacks of thylakoids; think of a big pack of life savers.

Question 14

stroma

Answer 14

fluid filled space outside the thylakoids.

Question 15

chlorophyll

Answer 15

the pigment that gives chloroplasts the green color.

Question 16

light reaction

Answer 16

absorption of light by plant pigments.

Question 17

why is chlorophyll green?

Answer 17

because red and blue light is absorbed and green light is reflected therefore it being green.

Question 18

what is a light reaction?

Answer 18

conversion of energy carried by light into chemical energy. Completely dependent on light.

Question 19

Calvin Cycle

Answer 19

use of chemical energy captured in the light reactions to “fix” carbon dioxide from the atmosphere into organic compounds; and doesn’t require light energy.

Question 20

What’s the goal of light reactions

Answer 20

to have enough energy to drive the calvin cycle.

Question 21

what does light energy do

Answer 21

light energy splits stored water molecules into hydrogen, oxygen, and electrons.

Question 22

what two molecules are used in the calvin Cycle

Answer 22

ATP and NADPH are used in the Calvin cycle; NADPH carry’s electrons like a taxi.

Question 23

What are the reactants in the Calvin Cycle

Answer 23

co2, ATP, and NADPH

Question 24

what are the products of the Calvin Cycle

Answer 24

G3P

Question 25

ATP and NADPH are generated in what reaction

Answer 25

The Light Reaction.

Question 26

Importance of the Calvin Cycle

Answer 26

removes 200 billion ton of co2 from the air every year.

Question 27

what protein is the most abundant protein on Earth

Answer 27

Rubisco

Question 28

Where do light reactions occur

Answer 28

in the thylakoid membranes

Question 29

light reactions do…..

Answer 29

convert light energy to the chemical energy of ATP and NADPH. Splits H20 and releases O2 as a waste product.

Question 30

Where does the Calvin Cycle take place?

Answer 30

the stroma

Question 31

What does the Calvin Cycle do?

Answer 31

uses ATP and NADPH to convert CO2 into G3P.

Question 32

some plants have what kind of limitations?

Answer 32

in hot, dry climates, opening stomata to allow CO2 to enter causes water to diffuse out of the cells.

Question 33

C4 plants

Answer 33

corn and sugarcane

Question 34

CAM plants

Answer 34

cactus, jade plants(succulent plants)

Question 35

After Photosynthesis is done the sugar produced……

Answer 35

supplies the plant with chemical energy; used to make all the major macromolecules(lipids, proteins), is consumed as fuel for cellular respiration, used to make cellulose for cell walls, is stored as a starch.
