(4 Points)

Answer 4

~ Amino group.

~ Carboxylic acid group.

~ Hydrogen atom.

~ R group.

Question 5

What Causes Amino Acids To Differ?

The position of the R group.

Question 6

What Bonds Form Between Amino Acids?

Answer 6

Peptide bonds.

Question 7

What Type Of Bonds Are Peptide Bonds?

Answer 7

Covalent bonds.

Question 8

What Is Needed In Order For A Peptide Bond To Form?
(2 Points)

Answer 8

~ A hydroxyl group lost from the carboxylic group of one amino acids.

~ A hydrogen atom lost from the amino group of another amino acid.

Question 9

What Happens To The Remaining Carbon Atom From The First Amino Acid?

Answer 9

It bonds to the nitrogen atom of the second amino acids, causing a condensation reaction.

Question 10

How Are Polypeptides Formed?

Answer 10

By the condensation of many amino acids.

Question 11

What Happens During Hydrolysis With Regards To The Peptide Bond?

Answer 11

The addition of water breaks the peptide bonds resulting in polypeptides being broken down into amino acids.
