question 9

Multiple Choice

A sequence of amino acids found in a subunit of the ATP synthase enzyme in several species is shown below.Which amino acids are likely to be most important to the function of ATP synthase?

• A)Those that are shaded dark blue because the amino acids are identical between species.
• B)Those that are shaded light blue because the amino acids are similar, but not identical.
• C)Those that are not shaded because the amino acid sequences are different between species.
• D)Comparing sequence between species does not indicate which amino acids are important to function.
