Total questions: 10
Worksheet time: 34mins
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
What is a of the functionsof a protein?
cell energy
structure
long term energy storage
contain genetic information
Why is folding so important in proteins?
It gives them a unique, 3-D 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'
What is it called when the unique 3-D shape of a protein has been disrupted or 'unravelled'?
Denaturation
Deproteination
Decoupling
Depeptidasing
Shape is essential for a protein to be functional?
Which of the following give a protein its unique 3-D shape? (3)
the unique sequence of amino acids in the primary structure
hydrogen bonding to form alpha-helixes and beta-pleated sheets in the secondary structure.
unique interactions between the 'R' groups in the tertiary structure
random folding due to temperature and extreme pH throughout the folding process
unique sequence of monosaccharides in the quaternary structure
