Understanding Catabolism

Catabolism refers to the biochemical reactions that involve the breakdown of complex molecules into simpler ones. This is a type of chemical reaction that releases energy.

Analyzing the Options

1. Chemical Decomposition: This is a reaction where a single compound breaks down into two or more simpler substances. This closely aligns with the definition of catabolism.
2. Direct Combination: This is the opposite process where two or more substances combine to form a more complex substance.
3. Double Displacement: This involves the exchange of ions between two compounds, which doesn't fit the description of catabolic reactions.
4. Combustion: This is a specific type of reaction that typically involves oxygen and results in the release of energy, often in the form of heat and light.

Conclusion

Given the definitions, the correct answer is Chemical Decomposition, as catabolism describes the breakdown processes characteristic of decomposition reactions.
