Scribe of the day

Hey y'all its catie here!

In class today, we...

-Discussed our pigment labs

-got grade reports

-began the lab on UP 73-76

-& discussed photsynthesis.

We spent a lot of time talking about photosynthesis. REMEMBER, WE HAVE A QUIZ ON IT TOMORROW!

Here's the scoop on photosynthesis:

-It all happens in the CHLORPLAST

-The STROMA is the name for the open space of the chloroplast

-The GRANUM is the 'stack of pancakes'. This is where the Light-Dependant reactions occur

-The 'pancakes' are called Phlatoids, and contain chlorophyll (which is the pigment nessecary to undergo phtosynthesis!

-The 'pancakes' also contain electrons

LIGHT-DEPENDANT reactions:

-Light comes in and hits the electrons, which gets them excited! Their energy level shoots up

-This splits the H20 molecules (which releases oxygen)

-Then, the electrons loose energy to form ATP

-The now split (or lonely) H+ molecule and NADP forms NADPH

-This carries nessecary energy to the CALVIN CYCLE

LIGHT-INDEPENDENT reactions: (a.k.a Calvin cycle)

-C02 is added to a 5 carbon sugar

-Engery from NADPH and ATP are used to carry out reactions

-Produces sugars (glucose!)

-DO NOT call this the 'dark cycle'! BECAUSE IT DOESN'T have to happen in the dark! This cycle doesn't care if its dark or light, it will still happen the same

OKAY BYE
