Proteins

Question 0

How does the shape of the protein determine its chemical properties and its function?

Answer 0

• 3D structure is important to its function
• activation site is unique to the protein *
• mutations can alter its shape
• can’t function how it was supposed to
• changes its chemical properties

Question 1

How does the sequence of amino acids in a protein determine its shape?

Answer 1

Sequence of amino acids causes chain to fold in its own unique way
- different shapes for different proteins

Question 2

What can alter a protein’s shape?

Answer 2

pH
Temperature
Polarity of the solvent
Concentration on ions that stick to the protein

-> can’t function properly
