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.
