What is the equation for photosynthesis?
energy + 6H2O + 6CO2 to C6H12)6 + 6O2
The light absorbing molecules in photosynthesis are referred to as __________________.
Describe a granum.
stacks of thylakoids
Describe the stroma
the fluid inside the chloroplast outside the thylakoids
What are the products of the light dependent reactions?
ATP, NADPH, and O2
Which photosystem starts the process of photosynthesis?
Which step of photosynthesis creates sugars?
In a chloroplast, where can the ETC, photosystem I and ATP synthase be found?
What causes the positive charge in the thylakoid membrane during the light dependent reactions?
H+ ions release from the splitting of water
What is the path the electrons flow during photosynthesis?
from water to NADPH to Calvin Cycle
What factors will affect the rate of photosynthesis?
temp, water, and sunlight
Organisms that use light to produce their own food are ______________.
Why would a plant appear blue?
The blue wavelengths are not being absorbed and are being reflected
Which color is least affective during the process of photosynthesis?
Describe the light reactions
Pigments absorb light and get electrons excited, phosphorylation produces ATP, electrons are transferred from water to NADP+, and Oxygen is produced
Where is ATP synthase found in a plant cell?
thylakoid membrane of chloroplasts and the inner mitochondrial membrane
What does the ATP synthase produce?
How are cell respiration and photosynthesis related?
Photo stores energy in organic molecules while cell resp. releases energy from organic molecules.
What are two products of noncyclic phosphorylation?
ATP and NADPH
What products of calvin cycle will be recycled back into the light reactions?
ADP, Pi, and NADP+
Chemiosmosis on plants will move protons from the ___________into the ___________________.
stroma; thylakoid compartment
List four molecules required for the Calvin cycle:
RuBP, NADPH, ATP, CO2

What is photorespiration?
enzymatic pathway that's coupled w/ ETC, does not generate ATP, use O2 to produce CO2, use sugar phosphate as its primary fuel
How does photorespiration affect the Calvin Cycle?
removes the RuBP
