a calcium puff is
A
an elementary event from a cluster of IP3 receptors
2
Q
a calcium spark is
A
calcium released from a cluster of ryanodine receptors
3
Q
smaller event than an elementary is called a
A
fundamental event
4
Q
fundamental event
A
calcium released from just one receptor (blip - IP3, quark - RyR)
5
