Enzymes are chiefly proteins, that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the procedure are called substrates, and the enzyme converts them into different molecules, called the merchandises. Almost all procedures in a biological cell need enzymes to happen at important rates. Catalytic power and specificity are the two features…

Glucocorticoids are so named because of early surveies bespeaking their function in glucose metamorphosis, the fact that they are synthesised in the adrenal cerebral mantle and because they are steroids. Cortisol is the chief glucocorticoid in worlds. The name glucocorticoid is really deceptive as glucocorticoids have many other maps non affecting the ordinance of glucose…

About 40% of the body’s sodium is contained in one, some is found within other organs and cells and the remaining 55% is in blood plasma and extracurricular fluids.

How did improvements in the microscope help scientists form the cell theory? 4. How do prokaryotic and eukaryotic cells differ? 5. Today, scientists can study human cell grown in Petri dishes. Explain how this…

I. Plasmids are important tools in molecular biology. Plasmids are small circular DNA that has the ability to enter and replicate in bacterial cells and can be used as vectors to introduce foreign genes into bacteria for cloning and sequencing. Any gene must be inserted into an appropriate location of a plasmid to be expressed….

A series in which the decrease electrode potencies of assorted electrodes have been arranged in the increasing order ( downwards ) is called Electrochemical Series. The standard decrease potency of H is zero.The electrodes above H have negative decrease potency while those topographic point below it have positive decrease potency and vice-versa. To understand the…
