When an enzyme is frozen, it only slows down activity. Unlike boiling an enzyme, it does not stop it from working.
No, freezing does not denature enzymes, however; it does slow the rate at which they are able to catalyse reactions. Denaturation is a permanent change in the conformation of an enzyme that renders it useless while freezing an enzyme only results in a temporary change.
Heat affect any enzyme and so pepsin. A temperature about 80 degrees can degarade most of the proteins and pepsin. At this temperature pepsin loose its structure and can not be active after that.
Freezing should have an effect on amylase. Amylase is an enzyme, which is therefore a protein, and has optimum conditions. Freezing it will severely slow it down, and I'm pretty sure will denature it, so yes it will completely reduce if not stop the effect of amylase. Freezing does not denature enzymes, heat does.

Higher the concentration of the solute, lower is the freezing point.
Freezing typically slows down enzyme activity by reducing the kinetic energy of the molecules, leading to a decrease in reaction rates. Boiling, on the other hand, denatures enzymes by disrupting the bonds holding the enzyme's three-dimensional structure together, effectively rendering the enzyme inactive.
Freezing can denature enzymes by causing ice crystal formation, which disrupts the structure of the enzyme. This can lead to a loss of enzyme activity when thawed due to damage to the enzyme's active site. Additionally, freezing can also lead to a decrease in enzyme stability and functionality over time.

Vinegar will not affect the freezing point of vinegar.
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
It doesn't
enzyme
Several factors affect the rate at which enzymes work: temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.If the amount of the enzyme is kept constant and the substrate is then gradually increased, the reaction speed will increase.The rate of an enzyme-catalyzed reaction increases as the temperature is raised. But freezing will inactive the enzyme and a very high temperature will destroy the enzyme.Very high or low pH values will result in complete loss of activity for most enzymes.Enzyme inhibitors are substances which alter the action of the enzyme and consequently slow down, or in some cases, stop the reaction.
No
Yes, lowering the pH of the enzyme solution can affect the enzyme's activity. Enzymes have an optimal pH at which they function best, so altering the pH can disrupt the enzyme's structure and function, potentially leading to decreased activity or denaturation.
