Answer:

The correct answer is A) Biochemical test

Explanation:

In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.

For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.

Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.

Which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
amid [387]

The statement 'interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane' explains why protein folding is critical. This process is fundamental for the function of transmembrane proteins.

Protein folding refers to the process by which a polypeptide (i.e., a protein) adopts its final tridimensional 3D shape (conformation).

In a protein, some amino acids contain hydrophilic R groups, whereas other amino acids contain hydrophobic R groups.

During protein folding, hydrophobic amino acids are arranged so they can interact with the long chains of the fatty acids in the internal region of the lipid bilayer, whereas hydrophilic amino acids are arranged so they interact with water on the surface of the cell membrane.
