The type of protein's inactivation that could lead to cancer if it stops working is: B. One that acts as a growth inhibitor
Explanation:
- Proteins that act as growth inhibitors are essential in regulating and controlling cell growth and division. They prevent cells from dividing too quickly or uncontrollably.
- Mutations or inactivation of these growth-inhibiting proteins, such as tumor suppressor genes like p53, can result in uncontrolled cell growth and division, a characteristic feature of cancer.
- Loss of function or inactivation of these proteins can lead to unchecked cell proliferation, contributing to the development and progression of cancer.
