Answer :
Explanation
2 important groups of macromolecules:
Carbohydrates
These substances are an essential part of our diet (for example grains, fruits, and vegetables). They provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods.
Carbs also have other important functions in humans, animals, and plants.
Proteins
These are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. Each cell in a living system may contain thousands of proteins, each with a unique function. Their structure, like their function, varies greatly.
