what word described the loss of enzymes original shape and the ability of it's active site to function?
Homework Answers
The word is denature. As denature means actually enzyme is a protein ,at high temperature the protien shape is altered and prevent from performing it's function ,then it has been denatured.

describe how enzymes act as biological catalysts that occurs at the active site. Discuss catalysis and competitive inhibition. how do each use the active site of the protein? what is an active site and why is it so inportant to biological catalysis.

In considering the 'active site' of enzymes, a fair generalization is that a. nearly all of the amino acid side-chains of the protein must directly participate in catalysis b. all the amino acid residues which are involved in the active site are adjacent because they are located on the same short stretch of polypeptide backbone c. the amino acid residues which form the active site are in close proximity because of the specific three-dimensional conformation the protein has adopted d....

Uncompetitive inhibitors bind to enzymes at a site other than the enzyme’s active site. Accordingly, A) Uncompetitive inhibitors can be outcompeted by substrate B) Uncompetitive inhibitors do not change the Vmax of an enzyme C) On a Lineweaver-Burke plot, increases in the concentration of uncompetitive inhibitor result in a y intercept that is further from the origin. Ie. a decrease in the Vmax
