which is a difference between proteins and carbohydrates and fats? proteins are macromolecules; carbohydrates and fats are not. proteins are composed of monomers; carbohydrates and fats are not. carbohydrates and fats contain carbon, hydrogen, and oxygen; proteins do not. excess carbohydrates and fats are stored; excess proteins are not.
Answer
Brief Explanations:
- All three - proteins, carbohydrates, and fats - are macromolecules. So the first option is incorrect.
- Proteins are composed of amino - acid monomers, carbohydrates of monosaccharides, and fats are composed of glycerol and fatty acids. So the second option is incorrect.
- Proteins, carbohydrates, and fats all contain carbon, hydrogen, and oxygen. Proteins also contain nitrogen and sometimes sulfur. So the third option is incorrect.
- Excess carbohydrates are stored as glycogen in animals and starch in plants, and excess fats are stored as adipose tissue. Excess proteins are not stored as such; they are either used for energy or converted into fat after deamination.
Answer:
Excess carbohydrates and fats are stored; excess proteins are not.
