unit 1, proteins

Question 1

what are the monomers that make up proteins

Answer 1

amino acids

Question 2

what makes up an amino acid

Answer 2

r group (variable) , carboxyl group, amine group , hydrogen , all joined to carbon

Question 3

what is the bond in proteins

Answer 3

peptide

Question 4

what is a polymer of proteins known as

Answer 4

polypeptide

Question 5

what happens in the primary structure

Answer 5

it’s a sequence of amino acids in a chain , the sequence of the amino acid can affect the tertiarty structure

Question 6

what happens in the secondary structure

Answer 6

hydrogen bonds form between the amino acids , causing them to form a alpha helix coil or a beta pleated sheet. the hydrogen bonds make it stable

Question 7

what happens in a tertiary structure

Answer 7

this is 3D shape of polypeptide chain, it creates a shape based on the sequence of amino acids as hydrogen bonds form in different areas , disulphide bonds occur between r groups

Question 8

what happens in the quaternary structure

Answer 8

more than one polypeptide chain joined together, an example is haemoglobin

Question 9

example of a chain like structure

Answer 9

collagen, structure in the skin

Question 10

example of a globular like structure

Answer 10

haemoglobin, carries oxygen in the blood
