Question

What distinguishes a major mineral from a trace mineral?

a) Their amount 100 per day
b) Their presence in bones
c) Their role in enzyme activation
d) Their requirement in smaller quantities

Answer 1

Major minerals are required in larger quantities (>100 mg/day) compared to trace minerals, which are needed in smaller quantities (<150 mg/day).

Step-by-step explanation:

A major mineral is distinguished from a trace mineral by the amount needed in the diet each day. Major minerals are required in larger quantities, typically more than 100 milligrams, while trace minerals are needed in much smaller quantities, usually less than 150 milligrams.

For example, sodium, potassium, calcium, and phosphorus are major minerals, while iron, zinc, and iodine are trace minerals.
