True. Enzymes are biological catalysts that significantly increase the speed of chemical reactions in living organisms.
Enzymes achieve this by lowering the activation energy required for a reaction to occur. Activation energy is the energy needed to start a chemical reaction, and enzymes provide an alternative pathway with a lower energy requirement. This allows reactions to proceed more quickly and efficiently.
For example, in the process of digestion, enzymes break down complex food molecules into simpler forms that our bodies can easily absorb. Without enzymes, these processes would occur at a much slower rate, making life as we know it impossible.
In summary, enzymes play a crucial role in speeding up chemical reactions, which is essential for maintaining life and supporting various biological functions.
