• A) Voltage-gated calcium channels would open and pass a large amount of inward current.
• B) Voltage-gated calcium channels would open and pass a large amount of outward current.
• C) Voltage-gated calcium channels would open but no current would pass through the open channel.
• D) Voltage-gated calcium channels would not open and therefore, not pass any current.
• E) Voltage-gated calcium channels would not open but a large amount of inward current would pass across the membrane.
