Monomers are....
the smaller building blocks for biomolecules
the complex components for biomolecules
the finalizing step to building biomolecules
Carbohydrates are also known as
Sugars
Fats
Acids
Bases
The repeating units of protein are
Amino acids
Glucose
Fatty acid
Peptides
Which of the following describes the secondary structure of proteins?
The sequence of amino acids
The α-helix and β-pleated sheet folding
The folding of the polypeptide chain due to the 'R' groups
The joining of different protein molecules to make one big molecule
Why is folding so important in proteins?
It gives them a unique, functional shape
It makes them look tidier
It makes every protein molecule different from the next even if they are the same type
The folding is random so is not that important at all
What happens to an enzyme when it is heated to above its optimum temperature?
Dies
Deforms
Denatures
Decomposes
Which protein structure describes the sequence of amino acids?
Primary
Secondary
Tertiary
Quaternary
Which protein structure describes a protein's three-dimensional shape?
Primary
Secondary
Tertiary
Quaternary
The difference between tertiary and quartenary structure is:
Tertiary structure has double bond whereas quartenary structure does not have double bond
Tertiary structure consists of one polypeptide chain whereas quartenary structure consists of more than one polypeptide chains
Tertiary structure is fibrous whereas quartenary structure is globular
Tertiary structure is water-soluble whereas quartenary structure is lipid soluble
