Serca pump - Study guides, Class notes & Summaries

Alpha 1 - correct answer contracts genitourinary smooth muscle; relaxes intestinal smooth muscle; heart, increases inotropy & excitability; liver, glycogenolysis & gluconeogenesis Alpha 2 - correct answer decreases insulin secretion, increases platelet aggregation, decreases norepinephrine release, contracts vascular smooth muscle Beta 1 - correct answer : increases rate, force, conduction velocity in heart; increases renin secretion Beta 2 - correct answer relaxes smooth muscle; glycog...

This document was my notes that I used to study for this exam. It is fairly short, But understanding these notes and subjects helped me greatly to critically answer questions about hemoglobin, chymotrypsin, Allostery ATCase, and the SERCA Pump.

Ryanodine receptors - ANS-responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle Dihydropyridine receptors - ANS-voltage-dependent calcium channel that triggers intracellular calcium release for excitation-contraction coupling troponin C, tropomyosin - ANS-Ca binds to ___________ and ____________ is removed therefore removing the inhibition of actin and myosin binding contracts - ANS-Actin and myosin binds...
