Question 1

Proteins are made up of:
A. Lipids linked together by hydrophobic interactions
B. Nucleotides linked together by phophodiester bonds
C. Monosaccharides linked together by glycosidic bonds
D. Amino acids that are linked together by peptide bonds (a type of covalent chemical bond)

Answer 1

D

Question 2

There is vast diversity in protein structure, hence protein function because:
A. The thymine (T), adenine (A) and cytosine (C) and guanine (G) bases making up the proteins can be chemically modified in many different ways.
B. Each type of protein is made up of its own unique sequence(s) of the 20 different standard amino acids.
C. Of the different types of chemical bonds that can form within proteins that are made up of the same sequence of amino acids.
D. The environment the proteins are in will change the some of its amino acids so that it performs the required function.

Answer 2

B

3. Haemoglobin
4. Trypsin
5. ATP synthase
6. Alcohol dehydrogenase 
A. Regulatory hormone

Question 4

The inside of the cell:
A. Is very crowded with cellular structures and proteins and other types of macromolecules.
B. Is spacious to allow enough space for the proteins to move between different locations.
C. Is filled with jelly-like substances that prevents the proteins from leaving their cell.

Answer 4

A

Question 5

The structure of a protein determines its function, true or false?

Answer 5

True
