PRIMARY STRUCTURE

Question 1

WHAT IS THE PRIMARY STRUCTURE OF PROTEIN?

Answer 1

SPECIFIC SEQUENCE OF AMINO ACIDS IN A POLYPEPTIDE CHAIN - JOINED BY PEPTIDE BONDS

Question 2

WHAT IS A DIPEPTIDE?

Answer 2

2 AMINO ACIDS JOINED TOGETHER BY A PEPTIDE BOND

Question 3

WHAT IS A POLYPEPTIDE?

Answer 3

3 OR MORE AMINO ACIDS JOINED TOGETHER BY PEPTIDE BONDS

Question 4

HOW IS A POLYPEPTIDE BOND FORMED?

Answer 4

AMINO ACIDS ARE JOINED TO EACH OTHER WITH PEPTIDE BONDS

Question 5

WHEN DO AMINO ACIDS JOIN TOGETHER?

Answer 5

DURING TRANSLATION AT THE RIBOSOMES

Question 6

WHAT IS THE REACTION OF JOINING AMINO ACIDS?

Answer 6

CONDENSATION REACTION

Question 7

WHAT IS A CONDENSATION REACTION?

Answer 7

FOR EVERY PEPTIDE BOND FORMED, A MOLECULE OF WATER IS PRODUCED

Question 8

HOW IS A PEPTIDE BOND BROKEN?

Answer 8

HYDROLYSIS - A MOLECULE OF WATER IS ADDED

Question 9

WHAT TWO THINGS ARE REMOVED DURING THE FORMATION OF A PEPTIDE BOND?

Answer 9

1. THE OH FROM THE CARBOXYL GROUP OF ONE AMINO ACID
2. A H FROM THE AMINE GROUP OF THE ADJACENT AMINO ACID

Question 10

WHAT FORMS A PEPTIDE BOND IN PROTEIN?

Answer 10

THE C OF THE CARBOXYL GROUP OF ONE AMINO ACID + THE N FROM THE AMINE GROUP OF THE ADJACENT AMINO ACID
