7.1-Autotrophs are the producers of the biosphere
I. Harnessing the sun’s energy
A. Introduction
1. Photosynthesis
a. The ability of an organism to convert light energy from the sun into ATP and carbo’s
2. What organisms are capable of photosynthesis
a. Autotrophs
1. organisms that make their own food

6. b. What type of autotrophs perform photosynthesis
1. Plants
2. Algae
3. Some bacteria
B. Photosynthesis has 2 stages
1. Capturing light energy (Light Reaction Stage)
2. Using light energy to make ATP (Calvin Cycle)
7.4-Photosynthesis is a redox process, as is cellular respiration
I. Equation of photosynthesis
II. Redox reactions: Oxidation & reduction
A. How does Photosynthesis yield glucose?
1. Transfer of electrons
a. Transfer of electrons releases stored energy
1. Used to synthesize glucose

7. B. The principle of redox
1. The transfer of electrons from 1 reactant to another
2. Oxidation
a. The loss of an electron
3. Reduction
a. The gain of electrons
4. Oxidation & reduction always go together
C. Oxidation of inorganic molecules during photosynthesis
CO2 + 6H2O + Energy C6H12O6 + 6 O2
1. CO2 gains electrons (in the form of H) from H2O
a. CO2 converted to C6H12O6
2. H2O looses electrons (in the form of H) to CO2
a. H2O converted to O2
Reduction

11.
I. 2 stages to photosynthesis
A. Light Rxn (Photo-)
B. Calvin Cycle (-synthesis)
II. Light Rxn
A. Capturing light light & pigments
1. Light from sun
a. Appears white
1. Composed of the visible spectrum
a. ROY G BIV

12. b. Light can either be absorbed, reflected, or transmitted
c. Pigments
1. A compound that absorbs light
a. w/o pigments all light would be white
2. Different pigments absorb different colors of light
a. The colors not absorbed are what is reflected or transmitted
1. These are the colors you see
2. Chloroplast pigments
a. Some terms
1. Chloroplast structures that house chlorophyll
2. Chlorophyll light absorbing pigments utilized in light Rxn
b. Chlorophyll
1. Several different types
a. 2 most important
1. chlorophyll a
2. chlorophyll b

13. 2. Chlorophyll a
a. primary pigment used in light Rxn
b. absorbs mainly red & indigo
3. Chlorophyll b
a. accessory pigment
1. assists chlorophyll a in capturing light
b. absorbs mainly blue w/ little indigo & orange

14. B. Converting light E chemical E
1. Step 1
a. Light E is absorbed by a cluster of chlorophyll called photosystem II
b. Absorbed light E causes electrons to enter a higher energy level
1. Excited electrons

15. 2. Step 2
a. Excited electrons leaves chlorophyll
1. Accepted by Primary Electron Acceptor
b. Water from the roots is split into 2 electrons and 1 oxygen molecule
1. Oxygen diffuses out of chloroplast and leaves the plant
2. 2 electrons replace electron that left chlorophyll

16. 3. Step 3
a. Excited electrons then get passed on to a series of electron acceptors
1. This is called the Electron Transport Chain
b. As electrons move down electron transport chain the energy it gained in step 1 is lost
c. The loss of energy is used to make ATP

17. 4. Step 4
a. Light E is absorbed by a different cluster of chlorophyll called photosystem I
1. This occurs at the same time as photosystem II
b. Absorbed light E causes electrons to become excited
c. Excited electrons leave chlorophyll
1. Accepted by primary electron acceptor
2. Lost electrons replaced by electrons from photosystem II
a. Electrons traveling down electron transport chain in step end up in photosystem I

18. 5. Step 5
a. Excited electrons then get passed on to a different electron transport chain
b. Energy gained in step 4 is lost
c. The loss of energy is used to make NADPH

21. III. The Calvin Cycle
A. The synthesis part of photosynthesis
1. Chloroplast captures CO2 from the atmosphere
2. Chloroplast then utilizes the ATP and NADPH ( Nicotinamide Adenine Dinucleotide Phosphate) from the light Rxn to combine CO2
a. ATP  ADP & NADPH  NADP
1. ADP & NADP return back to light Rxn to be recycled
b. The combination of CO2 is what creates sugar/glucose
1. Remember that glucose is nothing more than C, O, & H C6H12O6
