The three major issues that cut across psychology are stability versus change, rationality versus irrationality and nature-nurture issue.
Stability versus change deals with the issue of whether human beings change as they grow older or they remain essentially the same.
Rational versus irrationality illustrates the disparity between a human's mind ability to perceive and interpret correctly or incorrectly.
Nature - nurture issue centered on the relative contribution of genetic inheritance and environmental factors to human development.
Let's discuss first about difference between micro- and macro-nutrients. Micronutrients are those which are needed in small quantities and their function is not that vast. But macronutrients are the ones which control all the metabolic cycles of the cell, so they are needed in large quantities. This is the basic difference between the two terms.
Proteins are macro-nutrients because they are needed in large amount, as they are involved in some of the most important functions of our body. For example, proteins act as enzymes, involved in immunity, maintaining homeostasis of the body, etc. That is why they are considered as macronutrients.
