Prophase
During the prophase stage of mitosis, the nucleus seems to disband itself. The nucleolus suspends itself and finally, the nuclear membrane disassembles itself. This is because of the undergoing process of copying and dividing.
Mitosis is a functional cell dividing process that helps the cells repair or rejuvenate itself because of apoptosis and other factors.
Answer:
Allosteric enzymes bind at different site from the substrate binding site.
Explanation:
The activities of some enzymes, particularly those which form a part of a chain of reactions like metabolic pathways, are regulated internally. Some specific low molecular weight substances such as the products of another enzyme further on in the chain, acts as the inhibitor. Such a modulator substance binds with a specific site of the enzyme different from the substrate binding site. This binding increases or decreases the enzyme action. Such enzymes are called allosteric enzymes and the site at which they bind is called allosteric site.
Example: Hexokinase is an enzymes which converts glucose to glucose-6-phosphate in glycolysis. Decline in the enzyme activity by the allosteric effect of the product is called feedback mechanism, like the allosteric inhibition of hexokinase by glucose-6-phosphate,
