The article discusses enzymes, proteins that hasten the rate of biochemical reactions in plants and animals. Enzymes are needed for reactions to proceed, lowering the energy of activation to the level that enables reaction to start at normal growing temperatures. Not able to act alone, enzymes require the assistance of other chemicals, called cofactors or coenzymes, some in ionic forms of metals including magnesium, manganese and potassium, plant micronutrients essential for plant growth.
