BIOCHEMISTRY TEST REVIEW 2021

What is the main difference between these two polymers: Proteins vs Carbohydrates

• Proteins are made up of amino acids

• Proteins are made up of monosaccharides

• Proteins are made up of nucleotides

• Proteins are large molecules and carbohydrates are not

Both carbohydrates and lipids provide the body with energy, but lipids

• provide the body with MORE energy than carbohydrates

• provide the body with LESS energy than carbohydrates
