Question

1. how are enzymes important to living things?

Explanation:

Enzymes are biological catalysts. They speed up chemical reactions in living organisms. Without enzymes, many vital processes like digestion (e.g., amylase breaking down starch), cellular respiration (e.g., enzymes in the Krebs cycle), and DNA replication (e.g., DNA polymerase) would occur too slowly to sustain life. They allow reactions to happen at body temperature and in mild conditions.

Answer:

Enzymes are crucial as they act as catalysts, speeding up essential chemical reactions in living things (such as digestion, cellular respiration, and DNA replication) that are necessary for life processes to occur efficiently at body - compatible conditions.
