Question 12

What types of bonds hold atoms together so that molecules are formed?

Answer 12

Covalent bonds

Question 13

What type of forces profoundly influence the structures and behaviors of all biological molecules?

Answer 13

Weak forces

or Intermolecular forces (IMF)

Question 14

This weak force has its strength dependent on the relative size of the atoms or molecules and the distance between them.

Answer 14

Van der Waals forces

or London Dispersion Forces (LDF)

Question 15

This intermolecular force’s relative strength is proportional to the polarity of the H-bond donor and acceptor. It is also classified as H bonding to O, N, & F.

Answer 15

Hydrogen bonds

Question 16

this weak force is a complex phenomenon determined by the degree to which the structure of water is disordered as discrete hydrophobic molecules or molecular regions coalesce.

Answer 16

hydrophobic interactions
