Light-dependent reaction
answer
Captures energy from sunlight, takes place within and across the thylakoids, water and sunlight are needed
question
Light-independent reaction
answer
Use energy from light-dependent reactions to make sugars, take place on the storms of the chloroplast, carbon dioxide molecules are needed
question
Calvin cycle/dark reactions
answer
Use carbon dioxide gas from the atmosphere and the emery carries by ATP and NADPH to make simple sugars, cannot take place without the ATP from light-independent reactions
question
Photosynthesis equation
answer
6CO2 + 6H2O --> C6H12O6 + 6O2
question
Reactants of photosynthesis
answer
Reactants: water and carbon dioxide
question
Products of photosynthesis
answer
Products:glucose and oxygen
question
Glucose
answer
a simple sugar that is an important energy source in living organisms
question
ATP
answer
Energy
question
NADPH
answer
NADPH is an organic molecule, similar to NADH in animals, that is reduced in plants during photosynthesis.
question
H2O
answer
Water
question
O2
answer
Oxygen
question
CO2
answer
Carbon dioxide
question
Chlorophyll
answer
Light-absorbing pigment molecule in photosynthestic organisms
question
Grana
answer
the stacks of thylakoids embedded in the stroma of a chloroplast.
question
Stroma
answer
Pores in the cuticle of the plant through which has exchange occurs
question
Thylakoid
answer
Membrane bound structure within chloroplasts that contains chlorophyll and other light-absorbing pigments used in the light-dependent reactions of photosynthesis
question
Photosynthesis
answer
A process by which light energy is converted to chemical energy
question
Cellular respiration
answer
A process of producing ATP by breaking down carbon-based molecules when O2 is present
