Module 3 Photosynthesis

HideShow resource information
Autotroph
An organism that uses light energy or chemical energy and inorganic molecules to synthesise complex organic molecules
1 of 9
Heterotroph
Organisms that ingest and digest complex organic molecules, releasing the chemical potential energy stored in them
2 of 9
Nanometre (nm)
one thousandth of a micrometre, or one millionth of a millimetre
3 of 9
Photosynthestic pigment
Molecules that absorb light energy. Each pigment absorbs a particular wavelength and all others are reflected
4 of 9
Photophosphorylation
The making of ATP from ADP and Pi in the presence of light
5 of 9
Electron carriers
Molecules that transfer electrons
6 of 9
Electron acceptors
Chemicals that accept electrons from another compound. They are reduced while acting as oxidising agents
7 of 9
Light-independent stage
Where carbon dioxide is fixed and used to build complex organic molecules
8 of 9
What is the limiting factor for a metabolic process?
The factor that is present at the lowest or least favourable value
