What are Redox reactions?
Reactions that involve oxidation and reduction
Redox reactions occur in _______ and ______
Photosynthesis and respiration
What could have happened is something is oxidised?
- lost electrons
- lost hydrogen
- gained oxygen
When something is reduced what could have happened?
- gained electrons
- gained hydrogen
- lost oxygen
What is a co-enzyme?
A molecule that aids an enzyme
What is the role of a co- enzyme
- they transfer a chemical group from one molecule to another
- it can be reduced or hydrolysed
What is the co-enzyme in Photosynthesis
NADP
What does NADP do
- transfers hydrogen from one molecule to another
- reducing a molecule of hydrogen is taken from the original Molecule
