Briefly describe the following methods of regulation of enzyme activity in a cell
i) allosteric control
ii) covalent modification

Explanation:

i) Allosteric control

-Allosteric modulation is a mechanism whereby the activity of  an enzyme is either stimulated or inhibited by a compound  that binds to a site, called the allosteric site, that is dimensionaly different from the enzyme’s active site

ii) Covalent modification

-Covalent modification of enzymes, as illustrated by the addition (or removal) of phosphates, is a general mechanism for changing the activity  of enzymes.

-Enzymes that transfer phosphate groups to other  proteins are called protein kinases and regulate such diverse  activities as hormone action, cell division, and gene expression.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
