Final answer:
Enzymes are organic catalysts that speed up chemical reactions without being consumed in the process, making them reusable and vital for life processes. The statement is true.
Step-by-step explanation:
The statement that enzymes are organic catalysts that speed up a chemical reaction without being used up in the reaction is true. Enzymes are highly efficient in speeding up reactions by lowering the activation energy required for the reaction to proceed. These biological catalysts can catalyze reactions incredibly quickly, often taking a reaction that would normally take hours or days and completing it in less than a second.
Despite their catalytic action, enzymes are not changed or consumed in the reaction, making them reusable for subsequent reactions. Enzymes facilitate biochemical reactions that are essential for life processes, especially as most would not occur at a perceptible rate under normal conditions inside cells.
