Which Statement Best Describes the Mechanism of Sensitization

question 56

Multiple Choice

Which statement best describes the mechanism of sensitization?

• A) Protein kinase dephosphorylates Ca²⁺ channels and decreases the Ca²⁺ current that normally terminates the action potential, which leads to a decrease in Ca²⁺ influx.
• B) Protein kinase phosphorylates K⁺ channels and decreases the K⁺ current that normally terminates the action potential, which leads to an increase in Ca²⁺ influx.
• C) Protein kinase dephosphorylates K⁺ channels and increases the K⁺ current that normally terminates the action potential, which leads to an increase in Ca²⁺ influx.
• D) Protein kinase phosphorylates Na⁺ channels and decreases the Na⁺ current that normally activates the action potential, which leads to a decrease in Ca²⁺ influx.
