After injection, _______ cleaves the snare proteins of neurons, causing muscle contract to stop and no wrinkles to form.
botox
200

isotonic

300

During which type of skin cancer do keratinocytes proliferate into the stratum spinosa?

(Our three types are basal cell carcinoma, squamous cell carcinoma, and melanoma)

squamous cell

300

______ is released from the parathyroid in response to low calcium blood levels. This causes ______ to break down Ca deposits in the bone.

parathyroid hormone, osteoclasts

300

What is the difference between absolute and relative refractory periods? What channel must close in order for an absolute refractory period to become relative?

absolute- another AP cannot be fired because Na channels are still open. In relative, Na channels inactivate then close. An AP can thus be fired because Na can then reopen

oxidative phosphorylation- 32
