Popular Questions About Enzyme

What are enzymes and how do they work?
Enzymes are proteins that act as catalysts in a biochemical reaction to increase the rate of reaction without being used up in the reaction. Thousands of types of enzymes are at work in your body to carry out vital functions such as digestion and energy production.
Can you kill an enzyme?
Enzymes are not alive, so they cannot be killed. Typically though, bringing an enzyme to a boiling temperature is enough to denature it.
What is the thing an enzyme works on?
Generally, enzymes work on substrates in one of three ways: substrate orientation, physical stress, and changes in substrate reactivity . Substrate orientation occurs when an enzyme causes substrate molecules to align with each other and form a bond.
What is the difference between an enzyme and a protein?
• Enzymes are functional proteins, whereas proteins can be either functional or structural. • Unlike other proteins, enzymes are highly substrate specific molecules. • Proteins can be digested or broken down by enzymes (proteases).
