photosynthesis

Question 1

photosynthesis takes place in

Answer 1

in leaves- mesophyll cell- chloroplast- thylakoid membrane and stroma

Question 2

stomata

Answer 2

microscopic pore from which gases enter and exit

Question 3

function of veins

Answer 3

transportation

Question 4

Photon

Answer 4

Packet of fixed quantity of energy

Question 5

Photosystem

Answer 5

a light harvesting complex that use pigment bound to protein to transfer the energy of photon to the chlorophyll a molecule in the reaction center.

Question 6

Chlorophyll a

Answer 6

light capturing pigment that participate directly in light reaction, absorbs violet-blue and red color the most

Question 7

why transfer to chlorophyll a?

Answer 7

they can transfer an excited electron to a different molecule.

Question 11

Carotenoids

Answer 11

Pigment in chloroplast that absorbs excess damaging light.
Responsible for yellow, orange, and red colors of plants

Question 14

Chlorophyll b

Answer 14

accessory pigment, pass energy to chlorophyll

Question 15

Photosystem II

Answer 15

aka P680, occurs first, chlorophyll here absorbs 680 nm wavelength

Question 16

Photosynthesis occurs in how many steps?

Answer 16

2: Light - no light, occurs in thylakoid membrane
Dark: Occurs in stroma, makes sugar

Question 17

photolysis

Answer 17

Splitting of molecules by the action of light

Question 18

Photophosrylation

Answer 18

Process of formation of ATP from ADP by the addition of phosphate group. Occurs by the utilization of light.

Question 19

products of light reaction

Answer 19

ATP, NADPH and Oxygen

Question 19

Calvin cycle inputs and output

Answer 19

input: 3 CO2, 9ATP (6 for reduction and 3 regeneration), 6NADPH
outputs: 1 glyceraldehyde 3 phosphate(G3P) or aka 1/2 glucose

Question 20

Calvin cycle steps: Carbon fixation, reduction, and regeneration

Answer 20

photosystem I

Question 21

aka 700, Chlorophyll a absorbs light of wavelength
