Photosynthesis
Objective
SWBAT Describe the process of photosynthesis
Bellringer
What are the products and reactants of photosynthesis?
Slide2Adenine
Ribose
3 Phosphate groups
Cell Energy:
Cells usable source of
energy
is called
ATP
ATP stands for
adenosine
triphosphate
Slide3ADP stands for
adenosine diphosphate
Adenine
Ribose
2 Phosphate groups
Slide4All energy is stored in the bonds of compounds—breaking the bond releases the energyWhen the cell has energy available it can store this energy by adding a phosphate group to ADP, producing ATP
Slide5ATP is converted into ADP by breaking the
bond
between the second and third phosphate groups and releasing
energy
for cellular processes.
Slide6Choloroplast
Slide7ThylakoidsSack like photosynthetic membranesLight reactions take place
Inside the Chloroplast
Slide8GranaStack of thylakoids
Inside the Chloroplast
Slide9PhotosystemsProteins in the thylakoid membrane which organize chlorophyll and other pigments into clusters.Light collecting units of the chloroplast
Inside the Chloroplast
Slide10StromaRegion outside of the thylakoid membranesWhere dark reactions ( Calvin Cycle) takes place
Inside the Chloroplast
Slide11Chemistry Terms!
Reactant: a substance that changes during a chemical reaction.
Product: a substance produced during a chemical reaction.
Electron: a negatively charged part of an atom. It is the smallest of the 3 subatomic particles (neutron, proton, electron)
Slide12Transports high-energy electrons from the chlorophyll to other molecules on the Electron Transport ChainNADP+ is an electron carrier…that accepts the electron and makes NADPH NADPH is used to build various molecules such as glucose
Electron Carriers
Slide13Occurs in the thylakoids Needs light to occur, water, ADP and NADP+Produces ATP and NADPHHigh-energy electrons move through the ETC and excite the pigments that are in the photosystems
Light Dependent Reaction
Slide14Named after Melvin Calvin (American Scientist)Uses ATP and NADPH from the light-dependent reactions to produce high-energy sugarsDoes not require light to occur Dark reaction cycleLight-independent cycle

Slide16Summary:
Light Dependent Reaction
—H2O is broken down and light energy is stored temporarily in inorganic energy carriers, ATP and NADPHCalvin Cycle—energy is transferred from ATP and NADPH to the organic compound glucose
Slide17Light Reaction Process (occurs in the thylakoid membranes of the chloroplast)1. Light gets absorbed through the thylakoid membranes2. Electrons get excited and move H+ down the Electron Transport Chain3. NADPH and ATP (Energy) are made 4. Oxygen is Made and releasedDark Reaction Process (Calvin Cycle)Occurs in the Stroma5. NADPH and ATP are used to make glucose (C6H12O6)
Steps of Photosynthesis
Slide18Shortage of WaterPlants in dry conditions (deserts) contain a waxy coating on their leaves. Which helps to keep moisture in.TemperatureTemperature above or below the range of photosynthesis damage the enzymes which slows or stops the reaction from occurring Intensity of light Increasing the light intensity will increase the rate of photosynthesis
Factors that Affect Photosynthesis
Slide19Exit Ticket-Final 5
What are the products of the Light Reactions. (HINT: THERE ARE THREE THINGS)
Which of these products are used during the Dark Reactions.
What is another name for the Dark Reactions.
What are the products of the Dark Reactions.
5.:
In your own words explain to me why plant stems are green and not red. (Make sure to have complete sentences, use scientific language, should be more than just ONE sentence!)
