Photosynthesis Test Flashcards
Chlorophyll
light-absorbing pigment
Chemical energy
energy stored in the bonds of molecules
Radiant energy
energy that travels in waves
Aerobic
a process that requires oxygen
Anaerobic
a process that does not require oxygen
Stomata
pores on the surface of the leaf that allow gas exchange surrounded by guard cells
(pl. of “stoma)
Structure of stroma
Fluid-filled space inside the chloroplast
Structure of grana
Stacks of thylakoids
Structure of thylakoid
Small interconnected sacks
Type of organism that goes through photosynthesis
Autotroph
Type of organism that goes through cellular respiration
Heterotroph
What are the three parts to an ATP molecule
adenine, ribose, and phosphate groups
What are the differences between ATP and ADP
ATP has three phosphate groups and is charged, ADP has two and is like a dead battery
When a phosphate is added to ADP to become ATP energy is
Stored
When a phosphate is lost from ATP to become ADP energy is
Released
Photosynthesis equation
6 CO𝟤 + 12 H𝟤O —> C𝟨H𝟣𝟤O𝟨 + 6 O𝟤
6 carbon dioxide + 12 water —> glucose + 6 oxygen
What are the products of photosynthesis?
glucose, oxygen, NADPH
*What are the reactants of photosynthesis?
Carbon dioxide and water
*What is (are) the Electron Carrier(s) for photosynthesis
NADP+ (becomes NADPH when carrying the electron)

Thylakoid
*What is (are) the product(s) of the light-dependent reaction?
Oxygen and NADPH
Where does the light-independent reaction take place?
Stroma
What is (are) the product(s) of the light-independent reaction?
Glucose and water
Which of these stages is also called the Calvin Cycle
The light-independent reaction
