Which effect does a gradual decrease in pH from 13 to 1 have on the action of amylase?

pH can be described as a measure that is used to depict the acidity and alkalinity of a solution usually on a logarithm scale. Some enzymes in the body functions with pH (Hydrogen concentration).

The effect of pH with a gradual decrease from 13 to 1 on the action of amylase would cause amylase to not function and the enzyme to become denatured.

Some particular enzymes need specific hydrogen concentration (pH) to work. The pH scale measures this with 7 being neutral. Concentration lower than 7 becomes acidic going down to 1 and those higher than 7 becomes more alkaline going up to 14.

Amylase needs a pH range from 6 to 7 to function properly in the stomach but as the pH concentration becomes lower going to 1, the surrounding turns acidic causing the enzyme to become denatured and not function.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
