Flashcards in 6-7 Deck (28):
1

what is the equation for photosynthesis

CO2 + H2O + energy = C6H12O6 + O2

2

define photon

a packet of light where electromagnetic radiation occurs

3

the energy of a short wavelength vs a long wavelength is

short wavelengths have high energy and long wavelengths have low energy

4

what is the electromagnetic spectrum

when light from the sun passes through a spectroscope and the wavelengths separate

5

what is a chlorophyll

the light absorbing green coloured pigment that begins the process of photosynthesis

6

what are the two types of chlorophyll

chlorophyll A and B

7

what wavelengths do chlorophyll A and B reflect

500nm to 600nm (green light)

8

what does chlorophyll A do

A is the only one that can transfer energy from the sun to reactions of photosynthesis

9

what does chlorophyll B do

B is an accessory pigment that absorbs the photons A didnt absorb

10

what are chloroplasts

a membrane bound organelle in green plants and algal cells that carry out photosynthesis

11

the 6 parts of the structure of chloroplasts are

the stroma, thylakoids, grana, lamellae, thylakoid membrane, and thylakoid lumen

12

what is the stroma

a liquid inside the interior of chloroplasts

13

what are thylakoids

interconnected flattened membrane sacs inside the stroma

14

what are grana

stacks of thylakoids

15

what are lamellae

unstacked thylakoids inbetween grana

16

what is the thylakoid membrane

photosynthetic membrane that contains light gathering pigments and ETC

17

what is the thylakoid lumen

the fluid filled space inside a thylakoid

18

what are the 3 energy molecules formed in photosynthesis

ATP, NADH, glucose

19

how is ATP formed

when ADP and Pi come together

20

how is NADPH formed

it’s accepts one hydrogen atom and two electrons from NADP

21

what are photosystems

a cluster of photosynthetic pigments in the thylakoid membrane that absorbs light energy

22

what are the two photosystems

photosystem 1 and 2

23

what happens before and after a photon electron is absorbed

before the photon is absorbed there’s low energy and after it’s absorbed it has high energy

24

what is the electron transport chain

series of progressively stronger electron acceptors

25

what is photolysis

water molecules splitting into hydrogen ions and oxygen gas

26

what are the steps to electron transfer and atp synthesis

1. solar energy boosts electron
2. energy is released when passes down the ETC
3. some energy is used to make ATP
4. forms new compound when all energy is released

27

what is oxidation

gaining an electron

28

what is reduction

losing an electron
