Module 3: Intro to biological macromolecules

Question 1

Polar covalent bond

Answer 1

Electrons are shared unequally between atoms and spend more time close to one end vs the other. This results in partial negative and partial positive charges

Question 2

Electron transfer

Answer 2

When one atom loses an electron and another atom gains it. NaCl is a good example

Question 3

Electrolytes

Answer 3

Ions necessary for nerve impulse conduction, muscle contractions, and water balance (includes sodium, potassium, and calcium)

Question 4

Single bond

Answer 4

Two atoms sharing one electron each

Question 5

Double bond

Answer 5

Two atoms sharing two electrons each

Question 6

Triple bond

Answer 6

Two atoms sharing three electrons each

Question 7

Nonpolar covalent bonds

Answer 7

Form between two atoms of the same element, or between atoms of different elements that share electrons more or less equally

Question 8

London dispersion forces

Answer 8

Weak attractions between molecules, can occur between atoms or molecules of any kind and depend on temporary imbalances in electron distribution
