If you could design a modified version of the enzyme to ensure that it would function optimally in the harsh conditions of the washing vat (such as high temperature or high pH), which of the following could you do to achieve this goal?
A) Add more amino acids to the end of the protein to make it more hydrophobic.
B) Change the amino acid sequence slightly to ensure a more stable tertiary structure.
C) Remove some amino acids from the start of the protein to strengthen its secondary structure.
D) Change the amino acid sequence drastically to give the enzyme quaternary structure.

Changing the amino acid sequence slightly to ensure a more stable tertiary structure would be the best choice. This will help the enzyme to maintain its structure and function in harsh conditions by increasing its stability. Adding more hydrophobic amino acids or removing some from the start of the protein may not have a significant impact on the enzyme's ability to function optimally in harsh conditions. Drastically changing the amino acid sequence to give the enzyme quaternary structure may also alter its function and may not be necessary to optimize its function in harsh conditions.
