Photosynthesis Flashcards
What are Photosystems
clusters of chlorophyll in the thylakoids
What happens during the light-dependent reaction?
The light-dependent reactions use energy from sunlight Split Water Make oxygen Turn NADP+ into NADPH Turn ADP into ATP
What is a electron transport chain
A group of proteins that move electrons.
A Machine in Light Dependent Reactions
ATP synthase
An enzyme that allows H+ ions to pass through it to make ATP
Calvin cycle
Same thing at light independent reactions.
Carbon dioxide turns into sugar/glucose.
Uses ATP and NADPH
Occurs in the StRoma
What happens during the light-independent reaction.
ATP and NADPH (from the light-dependent reaction) and CO2 are used to produce high-energy sugars.
What some factors that affect the rate of photosynthesis
- temperature
- light intensity
- availability of water
Why is ATP useful to cells
ATP can easily release and store energy by breaking and reforming the bonds between its phosphate groups. This characteristic of ATP makes it exceptionally useful as a basic energy source for all cells.
Adenosine triphosphate is used by…
Is used by cells to store and release energy
ATP is an abbreviation for
Adenosine triphosphate
Heterotrophs are
Organisms that obtain food by consuming other living things
Autotrophs are…
Organisms that make their own food
Photosynthesis is
6H2O + 6CO2 —-> 6O2 + C6H12O6
Water + Carbon Dioxide makes Oxygen and Glucose/Sugars
What happens during the process of photosynthesis?
plants convert energy of sunlight into chemical energy stored in the bonds of carbohydrates (sugar)
Light Dependent happens in the
Thylakoids membrane
