Semmelweis Entrance Exam Medicine Biology 2023 Guide with Complete Solution. What are carbohydrates and lipids? Answer - Organic compounds that are mostly composed of three types of atom; carbon, hydrogen and oxygen What do carbohydrates do? Answer - provide energy, in the form of sugars like glucose and fructose, but they also make up structures like cellulose, which form the cell wall of plant cells What type of carbohydrate is the most important source of energy? Answer - mono-, di- an...
