Enzymes play a critical role in biological processes, with examples like amylase, lipase, and pepsin breaking down various nutrients in the human body. They are essential in all living organisms and can be influenced by cofactors, coenzymes, inhibitors, and feedback inhibition for optimal function and regulation.
Insights
- Enzymes play a vital role in biological processes, with examples like amylase, lipase, pepsin, and trypsin breaking down different types of molecules in the human body.
- Cofactors and coenzymes, such as zinc ions or vitamins, are crucial for optimal enzyme function, while inhibitors like DDT can have harmful effects, and feedback inhibition helps regulate enzyme activity based on product abundance.

Recent questions
What are enzymes and why are they important?
Enzymes are essential proteins that catalyze biological reactions. Understanding enzymes is crucial as many medications target them for treating diseases.
How do enzymes function in the human body?
Enzymes like amylase, lipase, pepsin, and trypsin break down carbohydrates, lipids, and proteins in the mouth, small intestine, and stomach, aiding in digestion.
Where are nucleases found and what do they break down?
Nucleases break down nucleic acids like DNA and RNA found in food by breaking phosphodiester bonds into nucleotides.
Are enzymes only present in humans?
Enzymes are not exclusive to humans but are found in all living organisms, including viruses and plants like the venus fly trap.
How do cofactors and coenzymes help enzymes?
Cofactors and coenzymes, like zinc ions or vitamins, aid enzymes in bonding with substrates, helping them function optimally.
