Mechanism of enzyme action
An enzyme is a three dimensional globular protein that has specific chemical composition due to
its component amino acids and a specific shape. Every enzyme by virtue of its specificity recognizes
and reacts with a special chemical substance called substrate. Any enzyme, therefore, reacts only
with its specific substrate and transforms it into product(s). It is then released unaltered and thus
can be used again and again.
An enzyme and its substrate react with each other through a definite charge-bearing site of an
closer and are arranged in a specific way by coiling and folding of the polypeptide chain within the

About This Channel.....................
I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
