Photosynthesis is the conversion of light energy to chemical energy via the production of carbon compounds.
Give the definition of photosynthesis.
Carotene or Xanthophyll or both
Give the name of at least one accessory pigment.
400-700nm
What is the wavelength of visible light ?
This pigment absorbs primarily blue and red light, playing a crucial role in photosynthesis.
What is chlorophyll?
This enzyme is responsible for fixing carbon dioxide in the Calvin Cycle.
What is Rubisco?
Carbohydrates; proteins; lipids and nucleic acids
What are the main groups of carbon compounds ?
What is chromatography used for ?
Chromatography is a technique used to separate components of a mixture (whereby separated parts/pigments can be identified)
used to show the rate of photosynthesis at each wavelength of light.
What is an action spectrum used for ?
This photosystem is primarily responsible for the production of NADPH in the light-dependent reactions.
What is Photosystem I (PSI)?
Carbon fixation, reduction, and regeneration of RuBP.
What are the three main phases of the Calvin Cycle?
carbon dioxide + water —> glucose + oxygen
Write down the equation of photosynthesis.
We can use a pen to trace the line in chromatography. True or False.
False: the ink can dissolve in the solvent.
Oxygen production and/or Carbon dioxide consumption should be measured
What should be measured in order to obtain the rate of photosynthesis ?
The light-dependent reactions occur in this membrane within the chloroplast.
What is the thylakoid membrane?
This process occurs when RuBP and CO₂ combine to form a six-carbon compound.
What is carbon fixation?
Carotene is the main light-absorbing pigment in leaves. True or False
False: it is chlorophyll
Oxygen (as a waste product)
What does photolysis release ?
Carbon dioxide; light intensity and temperature
Give the name of the three limiting factors for photosynthesis.
This process refers to the generation of ATP from the movement of protons across the thylakoid membrane.
What is chemiosmosis?
This three-carbon molecule is produced during the reduction phase and is essential for synthesizing glucose.
What is triose phosphate (TP)?
Blue and red light
What colour of light does chlorophyll absorbs best?
Prokaryotes were the first
Which organisms were the first to carry photosynthesis?
The Free-Air Carbon dioxide Enrichment experiment (FACE).
If scientists want to investigate the effect of elevated levels of carbon dioxide on the natural environnement, what experiment do they have to carry out ?
The primary electron donor in Photosystem II, which is involved in the photolysis of water
What is the oxygen-evolving complex (OEC)?
The phase of the Calvin Cycle that involves regenerating RuBP from triose phosphates.
What is the regeneration phase?
