6
Q

steps of light rxn

A

light energy gathered in chloro

electrons become excited & break away

ADP-ATP, NADP+-NADPH (charged battery)

water molecule split (pays back chloro)

Q

what happens when light enters the chloroplast

A

the electrons spin and break away, attach to ADP and NADP+ to create ATP and NADPH

16
Q

dark cycle in general

A

biochemical energy used to make glucose

17
Q

TF the dark cycle can hapen independently from the light rxn

A

F, it needs the energy from the light rxn to start the dark cycle

18
Q

General process of dark cycle

A

CO2+NADPH+ATP

P is removed from ATP-ADP
this releases energy

H is removed from NADPH-NADP+
this releases energy

sucrose is made

19
Q

Process of CO2 coming into leaf

A

from stomata diffused through mesophyll and parenchyma cells and then entered chloroplast

20
Q

What air molecules are used to make sugar

A

1 C and 1/2 of O2

extra O is lost as waste product

21
Q

where does P come in from atp

A

soil

22
Q

sucrose =

A

glucose + fructose
