Description:
This template shows calcium entering a cardiomyocyte through L-type calcium channels at the T-tubule following an action potential, triggering calcium release from the sarcoplasmic reticulum through RyR2 receptors. The released calcium drives sarcomere contraction, which is powered by ATP generated through the TCA cycle and electron transfer chain in the adjacent mitochondrion.
