Photosynthesis 🚨 Flashcards
(27 cards)
Three possible fates of the energised electrons that leave the chlorophyll
Return to chlorophyll,
Entered a cyclic pathway,
Enters a non cyclic pathway
Two molecules that can provide electrons during photosynthesis
Water,
Chlorophyll
Source of water for the plant for photosynthesis
Soil
One reasons horticulturalists might use carbon dioxide enrichment in a greenhouse
Increased photosynthesis,
Improving crop wield
Autotrophic
An organism that can make its own food
Why is photosynthesis a catabolic reaction
Small molecules to large molecules
In which cell organelle does photosynthesis occur
Chloroplast
Name pigment essential for photosynthesis
Chlorophyll
Two ways horticulturists can increase plant yields in greenhouse
More CO2,
Keep greenhouse at optimum temperature
Name given to water splitting in stage 1 using energy in light
Photolysis
What molecule is produced as a by product of the splitting of water
Oxygen
How is NADPH produced
Added electrons,
Added protons
Name stage 2 of photosynthesis
Light independent
What does ATP stand for
Adenosine triphosphate
Role of ATP
To release energy
What is the end product of stage 2
Glucose
Function of chlorophyll in plants
To absorb/trap light
Why is an advantage that chlorophyll contains a number of chemicals rather than just one
To absorb a greater range of light and more light
Events of dark stage photosynthesis
Co2 combines with electrons,
Co2 combines with protons,
To form glucose
How the dark stage is necessary for the continuation of the light stage
Products of dark stage are used in the light stage
Type of nutrition exhibited by organisms that carry out photosynthesis
Autotrophic
Role of stomata in photosynthesis
Gas exchange
Balanced question for photosynthesis
6Co + 6H2O —> CC6H12O6 + 6O2
Two products of light independent stage
Electrons and protons
