Question

Quizplus · Accepted Answer

Copper is a transition metal and can easily participate in redox reactions, generating reactive oxygen species (ROS) which are harmful to cells. Thus, copper must be bound to proteins in the blood to reduce its pro-oxidant activity and prevent oxidative damage. When copper is bound to proteins, it is transported safely to where it is needed, and is not allowed to accumulate in tissues where it could cause damage.
