Occupancy of Ca2+ buffers. Figure 22: Contributions of fractional occupancy of Ca2+ buffers in SR and cytoplasm. Transfer from O c and O tc to O tmgc occurs as a result of the pulse stimulation. O tmgmg is shown as a dotted line as it does not reflect Ca2+ binding. The corresponding [Ca2+] myo is overlayed (note the different axis)
