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….

Making Connections from last week…
Carbon Cycle by Annanimus Making Connections from last week…
4
Remember from BIO 1 AUTOTROPHS
Remember from BIO 1 AUTOTROPHS _____________ can make their own food using energy from sunlight. Ex: Green plants, a few bacteria
5
ATOMS CAN JOIN TOGETHER TO MAKE MOLECULES
Ex: Joining 2 HYDROGEN atoms with 1 OXYGEN atom makes ________ WATER A chemical formula tells what kind of molecules and how many are in a molecule EX: ________ H2O Image by: Riedell
6
________________ = kind of chemical reaction in which molecules are produced by joining smaller molecules together 2 H2 + O2 → 2 H20 SYNTHESIS Hydrogen molecule oxygen molecule 2 water molecules
7
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)
8
CELLS USE ATP TO STORE and RELEASE ENERGY
3 ____ PHOSPHATE GROUPS Adenosine triphosphate ATP = __________________________
9
ATP can change into ADP Adenosine diphosphate
2 ____ PHOSPHATE GROUPS Adenosine diphosphate ADP = __________________________
10
ATP releases energy stored in a high energy
ATP releases energy stored in a high energy chemical bond by removing the phosphate and becoming ADP ATP → ____ + ____ + ADP
11
THE BIG PICTURE → Carbon dioxide WATER Sugars Oxygen 6 CO2 6 H2O
_____________ + ____________ _______________ + ____________ 6 CO2 6 H2O → C6H12O6 6 O2 _____________ + ____________ _______________ + ____________
12
chlorophyll light energy In addition to water and carbon dioxide,
__________________ and are needed for photosynthesis to happen. chlorophyll light energy
13
Important Photoautotroph Vocab
Try the worksheet!
14
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? ? + ? ? + ?
15
Today’s Objective: Big Picture: Law of Conservation of Matter – Photosynthesis & Cell Respiration then: Detail the Light Rxn & Calvin Cycle 1st: get your notepacket & notebook out Review the chloroplast structure vocab Complete Part II : Use Diagram A to complete Diagram B
16
PHOTOSYNTHESIS HAPPENS IN CHLOROPLASTS
Proteins that are part of the thylakoid membrane organize ________________________________ into clusters called _____________________ Light absorbing PIGMENTS PHOTOSYSTEMS
17
LIVING THINGS NEED ENERGY CARRIERS
Molecule that carries = _______ Molecule that carries HIGH ENERGY ELECTRONS = ___________ ATP NADP+ Images by Riedell
18
HIGH ENERGY ELECTRONS require a special carrier, too
Frying pan image from: BIOLOGY by Miller and Levine; Prentice Hall Publishing©2006 HIGH ENERGY ELECTRONS require a special carrier, too ____________ is one of the carriers that cells use to transport high energy electrons. NADP+ ________ + _____ + _____ → ____________ 2 e- H+ _______= nicotinamide adenine dinucleotide phosphate
19
Photosynthesis consumed
____________________ involves a complex series of chemical reactions, in which the product of one reaction is _____________ by the next reaction. consumed Product Y Reaction 1 → Product → X Reaction 2 → A series of reactions linked in this way is referred to as a __________________________ biochemical pathway
20
Light-Dependent Reaction
PHOTOSYNTHESIS oxygen Light & Water Light-Dependent Reaction ATP NADPH (CH2O)n Carbon Dioxide Light-Independent Reactions Calvin Cycle
21
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!

LIGHT-DEPENDENT REACTIONS
INSIDE THYLAKOID SPACE ATP SYNTHASE ↓ PHOTOSYSTEM II ↓ ELECTRON TRANSPORT SYSTEM ↓ PHOTOSYSTEM I OUTSIDE THYLAKOID IN STROMA Image modified from: Pearson Education Inc; Publishing as Pearson Prentice Hall
24
LIGHT DEPENDENT REACTION
Requires ______________ Molecules are part of ________________ Made up of __________________ connected by ______________________ & ___________________ Uses light energy to change ADP + P → _______ NADP+ + 2e- + H + → _________ Breaks apart ______ molecules and releases _____________ LIGHT THYLAKOID membranes PHOTOSYSTEMS II & I ELECTRON TRANSPORT CHAIN ATP SYNTHASE ATP NADPH H20 oxygen
