BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Many essential reactions occurring within our cells are simply too slow to occur by themselves. For example, if the enzymes involved in respiration did not function properly, we would not be able to release enough energy in our cells to survive. Without enzymes we would be dead!

Detailed explanation-2: -Enzymes are proteins They act as catalysts, which means that they make biochemical reactions happen faster than they would otherwise. Without enzymes, those reactions simply would not occur or would run too slowly to sustain life.

Detailed explanation-3: -The regulation of the activation of these catalyzing enzymes is needed in order to regulate the whole reaction speed, so that it is possible to obtain the amount of product required at any time, that makes regulatory enzymes have a biological importance.

Detailed explanation-4: -Enzymes work consistently until they are dissolved, or become denatured. When enzymes denature, they are no longer active and cannot function. Extreme temperature and the wrong levels of pH–a measure of a substance’s acidity or alkalinity–can cause enzymes to become denatured.
