The speed of light in a vacuum stands at “exactly 299,792,458 metres per second“. The reason today we can put an exact figure on it is because the speed of light in a vacuum is a universal constant that has been measured with lasers; and when an experiment involves lasers, it's hard to argue with the results.

A variety of factors influence enzyme activity. Substances that bind to the enzyme and interfere with substrate binding or catal
Fofino [41]
<h3>Answer:</h3>

1. Irreversible Inhibition-Inhibitor may permanently modify an enzyme

2. Irreversible inhibition- Tamiflu, a transition state analog, reversibly binds to neuraminindase

3. Competitive Inhibition-Inhibitor binds reversibly to an enzyme's active

4.Irreversible inhibition-Inhibitor binds to an enzyme at a site other than active site

5. Mixed inhibition-The Al3+ ion binds to acetylcholinesterase or to the acetylcholinesterase- substrate complex

6. Irreversible inhibition-DIPF permanently modifies the hydroxyl group of a Serine residue at the active site

<h3>Explanation:</h3>
  • An enzyme is a biological catalyst that catalysis chemical reactions.
  • Enzyme activity is influenced by several factors which include enzyme inhibitors, temperature, and pH among others.
  • Enzyme inhibitors are molecules that bind to the enzyme thus interfering with enzyme activity and preventing the binding of substrate to the enzyme.
  • Inhibitors may either irreversibly or reversibly bind the enzymes.
  • Competitive inhibitors compete with substrates for the active sites while non-competitive inhibitors bind irreversibly to other sites on the enzyme other than the active site.
  • Tamiflu is an example of a competitive inhibitor.
  • DIPF is an example of a non-competitive inhibitor as it binds the enzyme permanently.
