Understanding Enzymes: The Basics
Before diving into the specifics of an enzyme webquest, it’s essential to understand what enzymes are and why they are fundamental to life.
What are Enzymes?
Enzymes are biological molecules, predominantly proteins, that act as catalysts to accelerate chemical reactions within cells. They are crucial for processes such as digestion, energy production, DNA replication, and more.
Key points about enzymes:
- They lower the activation energy required for reactions.
- They are highly specific to substrates.
- They are reusable, not consumed in reactions.
- They function best within specific temperature and pH ranges.
The Role of Enzymes in Living Organisms
Enzymes enable vital biochemical reactions to occur at rates compatible with life. Without enzymes, many reactions would proceed too slowly to sustain life processes.
Examples of enzyme functions:
- Amylase breaks down starch into sugars.
- Lipase digest fats into fatty acids and glycerol.
- Proteases cleave proteins into amino acids.
- DNA polymerase assists in DNA replication.
