Question

Quizplus · Accepted Answer

Trace elements include zinc, copper, and manganese, among others, and they are needed in small amounts. They are often involved in enzyme function, and can contribute to maintaining pH in the cell. Therefore, choice E is the best answer. Choice A is also correct, but it does not fully capture the importance and function of trace elements. Choices B and D are incorrect, as trace elements are not required in large amounts and are not solely responsible for maintaining the pH in the cell.
