In an experiment to study the effect of proteases on proteins, what is the most likely effect of a major change in ph? a) increased rate of product formation b) a change in the substrate concentration c) the formation of new active sites of the enzyme d) a change in shape of the active sites of the enzyme

The correct answer is-

D) a change in shape of the active sites of the enzyme.

Enzymes are primarily protein molecules that drive various chemical reactions ( by increasing the rate of reaction) within the body of living organisms.

Protease is a protein digesting enzyme that works on specific pH ( such as pepsin works on pH 2 within stomach, which is highly acidic) .

Shape of an enzyme determine its function as they have active sites ( which have unique shapes) that fit in the substrate and carry out the chemical reactions.

A major change in pH can alter the shape of the active sites of the enzyme, making it inactive.

Thus, option D) is the right answer.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

preservation because he preserves part of the land and preserves means save
