What is the conversion of solar energy into chemical energy performed by autotrophs?
Photosynthesis
Where does photosynthesis mostly occur?
Mesophyll (tissue in the interior of the leaf)
The green pigment located within chloroplasts is called what?
Chlorophyll
CO2 enters a leaf and O2 exits through pores called __________.
Stomata
What is the fluid within the chloroplasts?
Stroma
A system of interconnected membranes that divide the stroma from the thylakoid space
Thylakoid membrane
Where is chlorophyll located?
Thylakoid membranes
Thylakoid membranes that are stacked together are called what?
Grana
What are the 2 sets of reactions that make up photosynthesis?
Light reactions and the Calvin Cycle
Light is absorbed by chlorophyll and drives the transfer of electrons and hydrogen from water to ______.
NADP+
What are the light harvesting units of the thylakoid membrane called?
photosystems
What is released when water splits in a light reaction?
Oxygen
Where does the Calvin Cycle occur?
Stroma of the chloroplasts
The initial incorporation of carbon into organic compounds is called ___________________.
Carbon fixation
The Calvin Cycle uses ATP and NADPH to produce what?
Sugar
What are the three phases of the Calvin Cycle?
1. Carbon fixation
2. Reduction
3. Regeneration of RuBP
For every _____ molecules of CO2 that enter the Calvin Cycle, the net output is one molecule of G3P.
3
For each G3P synthesized, the cycle spends how many molecules of ATP and NADPH?
9 molecules of ATP
6 molecules of NADPH
