Personally no. I'd imagine enzymes throughout the body have environments that have varying pH levels. Although, pH is how many hydrogen+ ions there are. Many cells in the body may have the same or very similar pH levels but some parts of the human body may have higher or lower levels, meaning that the optimum pH for the enzyme depending on which part of the body it catalyses within.
Yeh, Its An Active Enzyme, i Think Its Mostly Active In Heat; Not Too Sure Though But It Is Definatley Active :)
i think it's the shape of the active site, the region where the enzyme comes into direct contact with the substrate. the shape of the active site is in turn determined by the structure of the enzyme, which is determined by the number and sequence of amino acids in the primary strucutre.(note that pH affects the shape of the active site as well.) just my guess.
I think its active an regulatory Correct The correct answer is a. active and regulartory. I just took the test
An allosteric enzyme is one in which the activity of the enzyme can be controlled by the biniding of a molecule to the "allosteric site". This really just means somewhere other than the active site. Thus allosteric control of an enzyme can be classed in two ways. A positive allosteric modification is the binding of a molecule to the enzyme which increase the rate of reaction. Sort of like catalysing the catalysing effect of an enzyme. Obviously the opposite is true of negative allosteric modification. A good example for this is the activity of phosphofructokinase, which is promoted by a high AMP concentration, and inhibited by a high ATP concentration. This should make sense if you think about the action of a kinase etc.
They are in active cells. Some like muscle and cardiac cells

I think the antonym is active
A repressor binds to the operator region of a gene and prevents RNA polymerase from transcribing that gene. It does not directly affect the active site of an enzyme, which is where the enzyme catalyzes its specific reaction.
Few people think ...

No, enzymes are highly specific in their function and typically catalyze specific reactions. This specificity is due to the unique structure of the enzyme's active site, which is complementary to the specific substrate it acts on. Using an enzyme in a reaction for which it is not specific is unlikely to yield the desired result.
I think it's more like 2 pds. Not including rice.
you are not human, you are a nut
I think every country has its human rights violations, they are just dealt with differently according to the way the laws are interpreted.
