Do Now: Alphabetizing Photosynthesis!

• In your notebook – Write A – Z down the middle of a page – It makes it easier!

• Fill in as much photosynthesis vocab that you can remember! – (Use your pink packet – pg 22/23 for help!)

• Maybe this video will help….• https://www.youtube.com/watch?

MAKING CONNECTIONS FROM LAST WEEK…

Remember from BIO 1

_____________ can make their own food usingenergy from sunlight.

Ex: Green plants, a few bacteria

AUTOTROPHS

ATOMS CAN JOIN TOGETHER TO MAKE MOLECULES

Ex: Joining 2 HYDROGEN

atoms with 1 OXYGEN atom makes ________

WATER

Image by: Riedell

A chemical formula tells what kind of molecules and how many are in a molecule

EX: ________H2O

________________ = kind of chemical reaction in which molecules are produced by joining smaller molecules together

2 H2 + O2 → 2 H20

SYNTHESIS

2 water molecules

Hydrogen molecule oxygen molecule

Energy Takes Lots of

Forms• Light Energy• Electric Energy• Chemical Energy

– Electrons in bonds– Lipids (very long storage)– Glycogen (large storage carb)– Glucose (short storage carb)– ATP (usable form)

CELLS USE ATP TO STORE and RELEASE ENERGY

ATP = __________________________Adenosine triphosphate

____ PHOSPHATE GROUPS

3

ATP can change into ADP

ADP = __________________________Adenosine diphosphate

____ PHOSPHATE GROUPS

2

ATP → ____ + ____ +

http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.html

ATP releases energy stored in a high energychemical bond by removing the phosphate and becoming ADP

Important Photoautotroph Vocab

• Try the worksheet!

Do you know the reaction?

• You have a unique molecule• Find 3 other people who will allow you to

become the reaction of photosynthesis• Arrange yourselves as a reactant pair and a

product pair?

____________________ involves a complex series of chemical reactions, in which the product of one reaction is _____________ by the next reaction.

Photosynthesis

consumed

Reaction 1 → Product → X

Reaction 2 → Product Y

A series of reactions linked in this way is referred to as a __________________________ biochemical pathway

PHOTOSYNTHESIS

Light-Dependent Reaction

Light-Independent Reactions

Light & Water

oxygen

ATP

NADPH

Carbon Dioxide (CH2O)n

Calvin Cycle

Main Idea

• Ultimate Goal – to make sugar (glucose)

• Two-Step Reaction– 1st step – Absorb energy from sun & capture it 1st

as electrons, then as ATP– 2nd step – use that ATP & the electrons to build

sugar from CO2!
