How Do Protein Kinases Generally Activate Their Target Proteins

question 11

Multiple Choice

How do protein kinases generally activate their target proteins?

• A)The process of phosphorylation causes the target proteins to change conformation.
• B)The kinases bind to target proteins directly, forming a complex that activates the proteins and lets them change conformation.
• C)Kinase concentrations vary during the cell cycle, so that proteins are activated only when kinase levels are high.
• D)Kinases bind to target proteins and inactivate them, so kinase levels must drop for target protein activation.
• E)The process of dephosphorylation causes the target proteins to change conformation.
