BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Under the conditions inside living cells, biochemical reactions would occur too slowly to support life without the help of enzymes. Enzymes increase the rate of biochemical reactions by reducing the amount of activation energy needed for reactants to start reacting.

Detailed explanation-2: -In the absence of enzymatic catalysis, most biochemical reactions are so slow that they would not occur under the mild conditions of temperature and pressure that are compatible with life.

Detailed explanation-3: -Enzymes are proteins – primary constituents of all living organisms. 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-4: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.

Detailed explanation-5: -The correct answer: The statement that is false about the enzymes d. A specific enzyme can catalyze a variety of chemical reactions. The enzymes are basically proteins that are produced from the secretory cells.
