Photosynthesis

QuestionAnswer
What happens to the electrons when light is absorbed. They get excited
Which colours of light does chlorophyll absorb red and blue
Colours of light absorbed by carotenoids not absorbing red and blue
Explain what happens during photolysis Water is split up into hydrogen and oxygen using light
Name the molecule that picks up hydrogen in the Light dependent stage NADP
Name the 2 molecules from the light reactions that are needed for Carbon fixation ATP & H/NADPH
State the two stages of photosynthesis 1. Light dependent stage 2. Carbon Fixation
State the molecule that combines with RuBP to make 3PG CO2
State the substances that need to be added for 3PG to become G3P ATP + hydrogen
Name the two molecules G3P can be turned into Glucose OR RuBP
Glucose can be turned into starch or cellulose
Describe the function of cartenoids absorb more colours of light and pass energy onto chlorophyll for photosynthesis
Name the 3 fates of light Absorb Reflect Transmit
The spectra that measures the colours of light where photosynthesis occurs is termed the action spectra
The by product that diffuses out the leaf during the Light dependent stage is oxygen
Describe how ATP is produced during the electron transport chain of the Light reactions Electron get excited and pass along chain releaseing energy to cause ATP synthase to make ATP.
Explain why the shade plant has a higher percentage of cartenoids than the sun plant above it, Plant above absorbs red and blue leaving green light to be transmitted to shade plant below.
