- 1What are the four macromolecules (including 3 nutrients)?Carbohydrates, proteins, lipids (fats and oils) and DNA.
- 2What elements make up carbs, proteins and fats?Carbs: CHO
Proteins: CHON (S) (P)
Fats: CHO - 3What are monosaccharides, disaccharides and polysaccharides?Disaccharides: Two monosaccharides
Polysaccharides: More than two sugar molecules - 4What are the three monosaccharide sugars?Glucose, Galactose and Fructose
- 5What are the three disaccharide sugars?Sucrose, Maltose and Lactose
- 6What is sucrose made up of?One glucose molecule, one fructose molecule
- 7What is maltose made up of?2 glucose molecules
- 8What is lactose made up of?One glucose molecule and one galactose molecules
- 9What are three polysaccharides?Glycogen, starch and cellulose
- 10What molecule is repeated to form glycogen, starch and cellulose?Glucose
- 11What is the difference between glycogen and starch?Starch is found in plants, glycogen in animals
- 12What are lipids composed of?3 chains of fatty acids and 1 glycerol molecule
- 13What are proteins made out of?Amino acids
- 14What is a string of amino acids called?A peptide
- 15Why do different proteins have different structures?Because the sequence of amino acids changes.
- 16What is the structure of DNA?A double helix
- 17What is each strand of DNA made out of, and in what order are they?Bases (AT,CG)
