The matter is everything around you. Atoms and compounds are all comprised of very small parts of matter. Those atoms go on to produce the things you see and touch every day. The matter is described as anything that has size and takes up space (it has volume).
Enzymes are proteins and speed up chemical reactions, i.e. are catalysts. Fats are lipids and store energy. Sugars are carbohydrates and also store energy. hope this helps :)
