Module 6: Figure elementary and global Ca2+ events

Elementary and global aspects of Ca2+ signalling.

Opening of entry channels in the plasma membrane or release channels in the endoplasmic reticulum (ER) give rise to elementary events. Sparklets at the cell surface trigger exocytosis, whereas sparks and puffs can activate a number of cellular processes. These elementary events can also be recruited to create regenerative Ca2+ waves that spread through the cell to produce a global Ca2+ signal. These elementary events are described in more detail in Module 6: Figure elementary events.
