Kategorikan yang berikut.
Organize these options into the right categories.
Kemasukan (Influx) of Na+
Sel menjadi lebih positif berbanding di luar sel
Menyebabkan systole (contraction)
Kemasukan ion Ca2+ dan ion K+ keluar (maintain depolarization)
Calcium channel tutup
Ion K+ terus keluar
Sel kembali kepada keadaan asal yang negatif
Menyebabkan diastole (relaxation)
