Enzyme Action

1) what is the region of an enzyme structure in which the substrate is attached called? Is it the active site or something else? 2) Is the activation energy of an enzyme-catalyzed reaction greater or less than that for a reaction in which no enzyme is present? 3) What is the difference between a competitive inhibitor and a ...continues

Use Le Chatelier's principle to explain why low pressure is used in the freeze-drying process

Use Le Chatelier's principle to explain why low pressure is used in the freeze-drying process (for example, in making instant coffee).

Ethanol and water are completely miscible; that is, they dissolve in each other in all proportions.

Ethanol and water are completely miscible; that is, they dissolve in each other in all proportions. (a) When the two substances are mixed, is randomness increased or decreased? (b) Heat is liberated in the dissolving process. Does the tendency toward minimum energy favour the separated pure substances, or the solution of ...continues
