Study Notes

Composition and Structure of Enzymes

  • Most enzymes are primarily made of proteins.
  • They are folded into four complex shapes which are crucial for their function.

Function and Reactions

  • Enzymes accelerate chemical reactions, enhancing the rate at which they occur.
  • They are involved in both anabolic (building up) and catabolic (breaking down) reactions.

Optimal Conditions for Enzymes

  • The optimal temperature for many enzymes is around 40 degrees Celsius.
  • pH levels vary for optimal enzyme activity; for instance, pepsin, active in the stomach, works best at pH 2, while trypsin in the small intestine functions efficiently at pH 8.
  • The optimal pH of an enzyme depends on its natural environment; intestinal enzymes favor around pH 7.5.

Effects of Temperature and pH

  • Temperatures above 40 degrees can reduce enzyme effectiveness and induce denaturation, altering enzyme structure.
  • Enzymes denature due to high temperatures and extreme pH levels, leading to a loss of function.

Denaturation and Reactivation

  • Denaturation refers to the process where proteins lose their shape, thereby losing function.
  • Denatured proteins can sometimes be reactivated if the denaturing agent (high temperature or extreme pH) is removed.

Enzyme Interaction and Reusability

  • Substrates bind to the active site of an enzyme, performing the reaction.
  • Enzymes can be reused multiple times after catalyzing a reaction, demonstrating their efficiency.

Enzyme Composition and Nomenclature

  • Enzymes can be made of proteins or RNA, functioning as biocatalysts.
  • RNA-based enzymes, known as ribozymes, are capable of building DNA.
  • The naming convention for enzymes typically ends with the suffix “-ase,” indicating their catalytic role.

Enzymatic Roles in Synthesis and Metabolism

  • Essential for protein synthesis, RNA synthesis, and DNA synthesis.
  • In addition to synthesis, enzymes facilitate cellular respiration (in lysosomes) and aid in human digestion.
