Competitive enzyme inhibition, Animation showing the effect of an enzyme (green) on a substrate (blue) under normal conditions and following non-allosteric competitive inhibition. Under normal conditions (first part of animation) the substrate is the correct shape to bind to the enzyme's active site (centre), and the enzyme promotes the cleavage (splitting) of the substrate into two products. When a competing chemical (the inhibitor, brown) binds to the enzyme's active site, it prevents the substrate binding there, and the promotion of the normal reaction is halted. An enzyme is a biological catalyst, increasing reaction rates without itself reacting or changing. For similar animations showing different aspects of enzyme activity and properties, see K004/4119 and K004/4122. For this animation with labels, see K004/4116. | |
