Considering the Active Site of Serine Protease Enzymes, a Fair

question 41

Multiple Choice

Considering the active site of serine protease enzymes, a fair generalization is that:

• A) Nearly all of the amino acid R-groups of the protein must directly participate in catalysis.
• B) All of the amino acid residues which are involved in the active site are adjacent because they are located on the same short stretch of the polypeptide chain.
• C) The conformation of the active site region does not exist at all until the substrate is bound to the enzyme.
• D) The amino acid residues which form the active site are in close proximity because of the specific three-dimensional shape the protein adopts in its native state.
• E) Only one amino acid residue is involved in the active site.

Understand and interpret the coefficient of determination.

Conduct hypothesis testing in the context of regression analysis to determine the existence of a linear relationship.

Explain the relationship between the coefficient of correlation and the coefficient of determination.

Distinguish between various statistical measures used in regression analysis (such as SSR, SSE, standard error of estimate).

Definitions:

Secondary Bronchi

The branches of the primary bronchi that lead into each lobe of the lungs, facilitating the transport of air.

Windpipe

Commonly known as the trachea, it's the tube that connects the larynx to the bronchi, providing air passage to the lungs.

Trachea

Also known as the windpipe, it is a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs.

Primary Bronchi

The two main branches of the trachea that lead directly into the lungs, providing the passage for air to enter and leave the lungs.
