Pectinases - Pectinases occur naturally in all fruit - including grapes - and are partly responsible for the ripening process. Grape pectinases are however inactive under the pH and SO2 conditions associated with winemaking.
Yes, it is an enzyme and all enzymes are proteins.
all enzyme names end in -ase so probably.
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
ase.Synthase, as exampleStill, not all enzymes have this ending. In the old days there were no naming rules. Pepsin, a digestive enzyme, is an example of non-naming by the modern rules.
No, not all Moscato wines are sweet. Some Moscato wines can be dry or semi-sweet, depending on the winemaking process and the level of residual sugar in the wine.
All Enzyme are proteins enzymes act as catalyst
it alters the pH of the enzyme denaturing it leaving it unable to carry out it's role effectively or at all
It is the Promoting Factors enzyme that does this
NADH
No, Vmax remains constant regardless of the amount of enzyme present. Vmax represents the maximum rate of reaction that can be achieved when all enzyme active sites are saturated with substrate. Once all enzyme active sites are filled, increasing the enzyme concentration further will not increase the reaction rate.
The rate of the enzyme-controlled reaction will increase until all enzyme active sites are saturated with substrate. After that point, the rate will remain constant as all enzyme molecules are already actively engaged, leading to saturation kinetics.
