Verified step by step guidance

Understand the role of catalysts: Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. In living organisms, these catalysts are crucial for facilitating biochemical reactions.

Identify the biological catalysts: In living organisms, enzymes are the primary catalysts. They are proteins that speed up metabolic reactions by lowering the activation energy required for the reaction to proceed.

Consider the nature of enzymes: Enzymes are highly specific to the substrates they bind to, and they operate under mild conditions of temperature and pH, which are typical of living organisms.

Evaluate the other options: Inorganic salts, synthetic polymers, and metal ions can act as catalysts in non-biological systems, but they are not typically the catalysts used in living organisms.

Conclude with the correct answer: Based on the understanding of biological systems, enzymes are the catalysts of reactions in living organisms, as they are specifically designed to facilitate biochemical processes efficiently.
