The following are the main steps in the generation of an action potential. Sodium channels are inactivated. Voltage-gated potassium channels open and potassium moves out of the cell, initiating repolarization. Sodium channels regain their normal properties. A graded depolarization brings an area of an excitable membrane to threshold. A temporary hyperpolarization occurs. Sodium channel activation occurs. Sodium ions enter the cell and depolarization occurs.   The proper sequence of these events is :

The following is a list of the steps involved in the process of secretion by the Golgi apparatus. 1.  Material moves from cisterna to cisterna by means of transfer vesicles. 2. Exocytosis. 3. Products from RER are packaged into transport vesicles. 4. Secretory vesicles are formed at the maturing face. 5.  Vesicles arrive at the forming face. 6.  Enzymes modify arriving proteins and glycoproteins.
