Zusammenfassung der Ressource
determine the
effect of calcium
ions on the
coagulation of
milk
- The
reaction is
catalysed
by the
enzyme
rennin
- Enzymes are protein
molecules that act as biological
catalysts
Anmerkungen:
- Look at what effects enzyme activity short notes
Anlagen:
- Calcium ions are cofactors for the
enzyme rennin by binding to
either the substrate or enzyme
they make the formation of
enzyme-substrate complex
easier.(affects charge distribution
and the shape of the
enzyme-substrate complex)
- So lower concentration of calcium ions will
decrease the rate of the reaction.
- While higher concentration of calcium ions
will increase the rate of the reaction
- Sodium substrate has to be
added as to remove all the
calcium ions that are normally
present in milk
- this than allows as to test the
effect of different
concentrations of calcium
ions.
