Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors that occupy

possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity is returned to normal. Such inhibitors interact with the enzyme by weak non-covalent bonds to form an enzyme inhibitor complex. E + I ⇌ EI B) Irreversible Inhibitors: These inhibitors bind very tightly to the enzyme‚ sometimes by

Chemical class: ACE inhibitors Action: ACE inhibitors reduce ACE. ACE converts angiostenin I to angiostenin II‚ which narrows heart vessels‚ which causes high BP. ACE inhibitors prevent ACE from converting angiostenin I to angiostenin II. This results in the dilation of blood vessel‚ which lowers BP. Adverse effects: Hypotension‚ angina‚ headache‚ fatigue‚ proteinuria‚ ‚ rash‚ sweating‚ cough. Contraindications: breastfeeding children‚ hypersensitivity to ACE inhibitors PREGNANCY (D) 2nd

By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked substrate in turn cannot join with the active
