The correct answer is C. Proteins.
Enzymes are proteins that catalyze, or speed up, chemical reactions in living things. They are essential for life, as they are responsible for a wide range of biological processes, including digestion, metabolism, and cell signaling.
Fats are a type of lipid that is made up of carbon, hydrogen, and oxygen atoms. They are an important source of energy for the body, and they also help to protect the organs and keep the skin healthy.
Carbohydrates are a type of nutrient that is made up of carbon, hydrogen, and oxygen atoms. They are the body’s main source of energy, and they also help to build and repair tissues.
Minerals are inorganic substances that are essential for the body. They are involved in a variety of bodily functions, including bone health, muscle function, and nerve function.
In conclusion, most enzymes are proteins. Fats, carbohydrates, and minerals are also important nutrients, but they are not enzymes.
