proteins intro (AA, Peptides, proteins )

Question 1

What can a variety of polymers be built from?

Answer 1

small set of monomers(common to all life

Question 1

What does synthesis require?

Answer 1

Energy.
It forms covalent bonds between components and eliminates water.
degradation the reverse

Question 2

What happens in a condensation reaction?

Answer 2

It joins two monomers with a covalent bond, removing water.(basically dehydration)

Water removal means the monomer becomes a residue within the polymer.

Question 3

What is anabolism?

Answer 3

Building up macromolecules usually REQUIRES energy input and enzymes.

Question 4

What is hydrolysis?

Answer 4

Reverse of the dehydration reaction, breaks two monomers apart by adding back a water molecule.

Question 5

What is catabolism?

Answer 5

Breaking down macromolecules usually RELEASES energy and needs hydrolytic enzymes.

Question 6

Give an example of a structural protein?

Answer 6

Collagen(bone connective tissue), Keratin(hair)

Question 7

Give an example of a storage protein?

Answer 7

Casein(milk), Ovalbumin(egg)

Question 8

Give an example of an enzyme protein?

Answer 8

Amylase(saliva)

Question 9

Give an example of a transport protein?

Answer 9

haemoglobin(blood oxygen), myosin(muscle)

Question 10

Give an example of a receptor protein?

Answer 10

Acteylcholine R(nerve, muscle), Antibody(blood)

Question 11

Give an example of a hormone protein?

Answer 11

Insulin(glucose metabolism)

Question 12

Give an example of a toxin protein?

Answer 12

Botulinum toxin (BoTox).

Question 13

What are proteins made of?

Answer 13

Amino acids.
