Penicillin works by irreversibly inhibiting an enzyme (transpeptidase) that catalyzes a crosslinking reaction in the formation of the bacterial cell wall.
Penicillin inhibits the transpeptidase by forming an irreversible covalent bond with the active-site serine residue in the enzyme

Why would the reaction of a normal rate of an enzyme slow down and its substrate slow down when a competitive inhibitor is present?
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
What is non-competitive enzyme inhibitor?
Competitive inhibition is where a inhibitor has a structural similarities of a substrate. Due this the inhibitor binds to the active site of the enzyme,where normally substrate binds. This binding of the inhibitor to the enzyme forms a EI complex instead of ES complex and thus inhibiting the catalytic activity of an enzyme. Non competitive inhibition is when inhibitor possessing same structure of substrate binds to the site other than the active site of an enzyme. The substrate binds to the active site of an enzyme. This binding of the inhibitor to the site other than an active site disturbs the normal structure of an enzyme. Thereby, lowering the catalytic activity of an enzyme.
What chemical agent that block enzymes?
This chemical is an enzyme inhibitor.
A drug that is used to treat AIDS by blocking the production of an enzyme?
Protease inhibitor
Poison that is an enzyme inhibitor but not a heavy metal?
example is alochol, ethanol, methanol
How do you use inhibitor in a sentence?
An enzyme inhibitor is a substance that binds to an enzyme and decreases the enzyme's activity.
Is penicillin an competitive inhibitor?
yes it is
Is penicillin a non-competitive inhibitor?
no
When the noncompetitive inhibitor is bonded to the enzyme?
The shape of the active site is distorted.
Which blocks enzyme activity by binding to the site of an enzyme?
inhibitor
A noncompetitive inhibitor has a structure that?
A noncompetitive inhibitor has a structure that does not resemble the substrate structure. A compound that binds to the surface of an enzyme, and changes its shape so that a substrate cannot enter the active site is called a noncompetitive inhibitor.
Blocks the action of the enzyme that causes the blood vessels to contract resulting in hypertension?
ACE inhibitor
What is a role of beta lactamase inhibitor?
Some bacteria produce beta lactamase enzyme, this enzyme will break the beta lactam ring structure of certain antibiotics (penicillin, cephalexin for example) rendering them ineffective against the infection. If you add a beta lactamase inhibitor to a beta lactam antibiotic (i.e clavulanaic acid added to amoxicillin) it decreases the potential of the bacteria to inactivate the antibiotic.
What happens to the vmax when a competitive reversible inhibitor is added to an enzyme?
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
What is an enzyme inhibitor that isn't a heavy metal?
Ricin
What is Lotensin?
It is an angiotensin-converting enzyme (ACE) inhibitor
What is Capoten?
It is an angiotensin-converting enzyme (ACE) inhibitor
