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?
? + ? ? + ?
Today’s Objective: Big Picture:Law of Conservation of Matter –
Photosynthesis & Cell Respirationthen:

LIVING THINGS NEED ENERGY CARRIERS
Molecule that carries= _______
Molecule that carries HIGH ENERGY ELECTRONS
= ___________
ATP
NADP+

________ + _____ + _____ → ____________
HIGH ENERGY ELECTRONS require a special carrier, too
____________ is oneof the carriers thatcells use to transporthigh energy electrons.
NADP+
2 e- H+
_______= nicotinamide adenine dinucleotide phosphate

____________________ 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!
