Hi, i was just wondering what is the effect of calcium ions on rennin and on the rate of oagulation of milk. i have found out some information that the inorganic calcium ions act like cofactors which need to be present for rennin to coagulate milk. i need more information please as this is not enough.
Calcium ions speed up coagulation, because they act as cofactors for the enzyme. That IS enough information - the actual mechanism is very complicated and far beyond what would be expected at AS level!
