When 20% calcium is added to the solution it enables more than(prenominal) calcium to bind to the receptors, thus causing more contractions. However, when we replaced the low calcium bath with a high calcium bath the contractions nearly stopped. This is due to an overload of calcium.
There is besides much(prenominal) calcium and they are all fighting to bind with the receptors, halt them and causing none of the calcium to be able to bind.
