During photosynthesis, light energy is used to create sugars that store energy in their bonds. Using your knowledge of photosynthesis, how is this light energy transferred throughout the cell to become chemical energy in food?

• Energy is transferred directly to the sugars, with no intermediate molecules

• Energy is transferred to sugars through H20, O2, and CO2

• Energy is transferred to sugars through ATP and NADPH

Using the following model and your knowledge of the Light-Dependent Reaction and Calvin Cycle, should Carbon Dioxide be included as a reactant or product? If so, how should it be included?

• Yes, as reactant A

• Yes, as product B

• Yes, as Reactant C

• No, it should not be included

T/F: The Calvin Cycle uses sunlight energy to create intermediate molecules ATP and NADPH to be used to make sugars in the Light-Dependent Reaction.

• False

• True

High-energy electrons are transported from chlorophyll to other molecules in the chloroplast by...

• The thylakoid membrane

• ATP Synthase

• NADP+

What does Carbon Dioxide assist in during the process of photosynthesis?

• CO2 is used to create sugars

• CO2 is not used in photosynthesis, but is released into the air

• CO2 is an electron carrier

SELECT ALL THAT APPLY:

Which of the following are the reactants (Inputs) of photosynthesis?

• 6H2O

• C6H12O6

• 6O2

• 6CO2

What is the Role of the Photosystems in the Light-Dependent Reaction?

• To transfer electrons to the electron carrier NADP+ to create NADPH

• Helps attach RuBP and CO2 together to form a 3 carbon molecule

• Uses light to directly create Glucose (C6H12O6) inside the thylakoid

• Uses light to excite electrons and send them to the ETC to be used
