Explanation:

<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>

<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>
