Total questions: 20
Worksheet time: 15mins
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
The main bonding in the secondary structure of a protein is due to.....
covalent bonding
ionic bonding
hydrogen bonding
polar bonding
The tertiary structure folding in proteins is primary due to the interactions of....
the 'R' groups
the 'P' groups
the 'A' groups
the 'S'
The repeating units of protein are
Amino acids
Glucose
Fatty acid
Peptides
What is the main function of protein in the body?

Helps to transport vitamins through the body
All of the above are roles of protein in the body
Which describes the functions of proteins in living things?
structural, transport, signaling, catalysts, etc.
stores and transmits genetic information
stores energy and makes up cell membranes
quick energy and forming cell structure
