When bacteria multiply, they produce waste products known as what?

When bacteria multiply, they produce waste products known as toxins. Toxins are harmful substances that can interfere with normal bodily functions and can lead to foodborne illnesses. These waste products can cause a variety of health issues, ranging from mild symptoms to severe reactions, depending on the type of bacteria and the quantity of toxins produced.

Enzymes, while produced by bacteria, are not considered waste products. They are catalysts that help in the breakdown of food in the digestive system or facilitate other biochemical reactions. Antigens are substances that provoke an immune response and are not waste products of bacterial growth. Pathogens refer to microorganisms that can cause disease, but they are not the waste products produced by bacteria as they multiply. Thus, the correct association of bacteria multiplying and producing waste is through toxins.
