Ch. 9: Photosynthesis: Capturing Light Energy

Question 1

what is the formula for it

Answer 1

6CO2 + 12 H2O + light energy –> C6H12O6 + 6O2 + 6H2O

Question 2

how many wavelength types

Answer 2

two: long and short

Question 3

__ wavelengths have __ energy (tv/radio/microwaves)

Answer 3

long; low

Question 4

_- wavelengths have _- energy (uv; x-ray; gamma rays)

Answer 4

short; high

Question 5

__ measure wavelength

Answer 5

nanometers

Question 6

__ is composed of small particles (packets of light energy called __-)

Answer 6

light; photons

Question 7

when a photon hits an atom, it __ and is __ by an electron trasporter

Answer 7

makes energy/emit; accepted

Question 8

__ is not in all plants and have 2 membranes

Answer 8

cholorplast

Question 9

__ have mitochondrias

Answer 9

plants

Question 10

__ is the __ of chloroplasts

Answer 10

stroma; cytoplasm

Question 11

__ is a flat membrane sac found in the stroma

Answer 11

thylakoid (where almost evrything takes place)

Question 12

_- is found inside the chloroplast

Answer 12

stroma

Question 13

__ is a green pigment and the main pigmen tof photosynthesis

Answer 13

chlorophyll

Question 14

__ is an accesory pigment

Answer 14

carotenoids

Question 15

__ dependednt rxn take place where

Answer 15

light; thylakoid (h2o in, it is split, and o2 goes out)

Question 16

_- reactions take place in stroma

Answer 16

co2 fixations (co2 in; carbs out) (energy is transferred from atp to nadph molecules produced by light dep. rxn to chemical bonds on carbs)

Question 17

adp to atp

Answer 17

phosphorylation

Question 18

nadp+ t nadph

Answer 18

reduction

Question 19

atp to adp d

Answer 19

dephosphorylation

Question 20

nadph to nadp+

Answer 20

oxidation

Question 21

fixation means

Answer 21

to make something usuable

Question 22

o2 in, co2 out

Answer 22

humans

Question 23

co2 in, o2 out

Answer 23

plants

Question 24

what is the electron transporter in photosyn

Answer 24

nadp+

Question 25

all photosystems are __

Answer 25

integral transmembrane proteins

Question 26

photosystems are found where?

Answer 26

thylakoid membrane

Question 27

how many types of photosystems; their names; and what they refer to

Answer 27

2; p700 (#1) and p680 (#2) [but p680 is before p700]; refer to long wavelengths

Question 28

photosystem steps:

Answer 28

1. photon hits p680
2. p680 splits h2o into o2 and h+
3. electrons from p680 go through etc to make atp
4. electrons then go to p700
5. a new photon hits p700
6. elctrons are excited (gain energy) and go to another etc
7. eletrons join with nadp+ to reduce it to nadph

Question 29

products of light dependent rxn

Answer 29

nadph and atp

Question 30

__ cycle has 3 names and doesn’t take place in thylakoid lumen (happens in stroma instead (the fluid part) due to it’s light independency

Answer 30

calvin cycle (calvin cycle, light independent rxn, carbon fixation)

Question 31

light independent reactants

Answer 31

12 nadph and 18 atp

Question 32

photosyn is an __ pathway (small–>big)
- opp of cell resp (which is catabolic) (c and c)

Answer 32

anabolic (p and a)
