plants?
chloroplasts - CORRECT ANSWER - What is the structure where photosynthesis occurs?
stoma (stomata) - CORRECT ANSWER - Openings that open and close where CO2 enters
the leaves (Plural is known as ______).
6CO2 + 12H2O + Light Energy -> C6H12O6 + 6H2O + 6O2 - CORRECT ANSWER -
Overall equation for photosynthesis
Carrier (shuttle) for Hydrogen atoms (to reduce power w/in calvin cycle and turn CO2 into
glucose) - CORRECT ANSWER - What is the purpose of NADP?
Photosystem II, Photosystem I - CORRECT ANSWER - 2 stages of photosynthesis
Create ATP and NADPH - CORRECT ANSWER - Overall purpose of light reactions
Thylakoids (bitch is a hoarder) - CORRECT ANSWER - Stacked columns, called grana,
of ____ within chloroplasts where light reactions occur.
ATP (adenosine triphosphate) and NADPH (the electron carrier) - CORRECT ANSWER -
What products are generated from light reactions?
Calvin cycle - CORRECT ANSWER - Where to the products from light reactions go?
, Chlorophyll molecules become excited from photon light, and react with other chlorophyll
molecules that push electrons to the reaction center - CORRECT ANSWER - How do
electrons move through the light reactions? (Part 1) (Describe)
Electron transport system sends electrons to create ATP, through the ATP synthase enzyme
(protein), and NADPH when attached (reduced) to NADP+ in the last phase of the electron chain
of the light reactions of photosynthesis. - CORRECT ANSWER - How do electrons move
through the light reactions (Part 2) (Describe)
Make glucose (and other sugars) - CORRECT ANSWER - Overall purpose of the Calvin
Cycle
stroma - CORRECT ANSWER - Where does the Calvin Cycle occur?
2 G3P (glyceraldehyde-3-phosphate) molecules, 2 ADP (adenosine triphosphate), and 2 NADP+
(Nicotinamide adenine dinucleotide phosphate) - CORRECT ANSWER - What are the
products of the Calvin Cycle (one turn)?
