You Take a Human Smooth Muscle Cell and Block the Release

question 173

Multiple Choice

You take a human smooth muscle cell and block the release of calcium from the sarcoplasmic reticulum. What effect does that have on contraction of that smooth muscle cell, and why?

• A)Contraction is completely blocked because calcium binding to troponin is required for contraction.
• B)Contraction is completely blocked because calcium binding to calmodulin is required for contraction.
• C)Contraction still occurs because Ca²⁺ can enter the cell directly through Ca²⁺ channels in the plasma membrane and bind to troponin.
• D)Contraction still occurs because Ca²⁺ can enter the cell directly through Ca²⁺ channels in the plasma membrane and bind to calmodulin.
• E)Contraction still occurs because contraction in smooth muscle is completely independent of Ca²⁺ levels.
