How do enzymes work, and why can genes change them?
Human BiologyBiochemistry
Quick Answer
Enzymes are proteins that speed up chemical reactions in the body. Genes determine the enzyme’s structure, so a mutation can change how well it works.
The Full Story
Enzymes act like biological catalysts, lowering the energy needed for a reaction to happen. Each enzyme’s shape allows it to bind a specific substrate and carry out a particular step in a pathway. Because genes encode the amino-acid sequence of proteins, a mutation can alter an enzyme’s shape, stability, or activity. That is why some genetic mutations have major effects on digestion, metabolism, or disease.
