Final answer:
Option (B), The incorrect statement regarding enzymes is that they are consumed in the reactions they catalyze.
Step-by-step explanation:
The statement that is not true about enzymes is B) Enzymes are consumed in the reactions they catalyze. Unlike other catalysts, enzymes are not used up in the chemical reactions they help facilitate. Instead, they can be utilized repeatedly. Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed, making them much more efficient.
They are also highly specific for their substrates, meaning each enzyme tends to bind to one or just a few types of molecules and catalyze a specific type of reaction. However, enzymes can be denatured by extreme conditions such as high temperature or drastic pH changes, which negatively affect their functional shape and, therefore, their activity.
