Plato ... Read More

Importance of Enzymes in Biological Reactions (418 words, 1 pages)

Enzymes are biological catalysts. They increase the speed of a reaction, without being affected or altered themselves. Our bodies contain hundreds of enzymes, each catalysing a particular reaction (increasing the reaction's speed), by reducing the amount of energy required to activate the reacting molecules - the activation energy. Enzymes are ... Read More
