wat is the importanve of the shape of an enxyme in catalysing cell reactions?

Question

how can i show this in a diagram too

Answer 1

Enzymes work by bringing together two reactants in such a way that the parts on the reactants that interact are close to each other. This facilitates the reaction by lowering the energy of activation.
If an enzyme is misshapen, then the reactants will not be in the correct orientation for the reaction to occur. Thus, it is crucial that enzymes not be denatured.

Answer 2

The shape of the enzyme must fit the shape of the substrate. It's like a jigsaw puzzle. See sample diagrams here:

Answer 3

as stated, the shape of an enzyme is crucial to it's activity. The active site of the enzyme, to which catalytic activity is attributed, is a pocket to which the substrates must bind.
Fischer's lock & key hypothesis is a basic model to explain enzyme activity. In this, the enzyme is a lock to which the substrate key binds at the pocket of the active site, thereby activating it.
A more relevant model is the Induced Fit hypothesis, which visualizes the enzyme not as a rigid 'lock' but as changing conformation as the substrate arrives in the vicinity, so as to accomodate and bind substrate and subsequently activating it.

Answer 4

Any enzime must keep its native structure to be functional, that means to have the proper active groups in position .
