Answer:

$\boxed {\tt 2nd \ Answer}$

Explanation:

An enzyme is a protein that speeds up a chemical reaction. Enzymes are shape specific. The active site is a specific shape, which means it can only break down specific substrates.

Certain conditions can denature enzymes. For example, extreme temperatures or pH will cause the enzyme to deform and change shape, which means it cannot perform its job.

Therefore, the best choice is the second one: enzymes work best in specific conditions and only break down specific substrates.

Which technique could be used to evaluate the primary amino acid sequence of a protein?

Softa [21]

Answer:

Hundreds of proteins have been sequenced by Edman degradation of peptides derived from specific cleavages. Protein Mass Spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles for determining masses of particles and the elemental composition of a sample of molecules as well as for elucidating the chemical structure of molecules such as peptides. Protein mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.
