WebEnzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions. WebSep 7, 2024 · Each enzyme has a highly specific geometric shape that is complementary to its substrate. In order to activate an enzyme, its substrate must first bind to the active site on the enzyme. Only then will a catalytic reaction take place. However, like a lock and a key, the enzyme and substrate shape must be complementary and fit perfectly.

The enzyme dihydrofolate reductase is shown with one of its substrates: NADP + (a) unbound and (b) bound. The NADP + (shown in red) binds to a pocket that is complementary to it in shape and ionic properties. The active site of an enzyme possesses a unique …
WebNov 22, 2024 · The enzyme that speeds up the digestion of lactose is called lactase. Lactase and most other enzymes are proteins. Each enzyme has an active site where a substrate molecule binds. For example, the substrate lactose binds to the active site of the enzyme lactase. Notice that the name of the enzyme lactase was created by adding the … WebEnzymes are generally quite specific for their substrates. Although lactase and pepsin both catalyze the same type of reaction, breaking a bond using water (hydrolysis: “hydro” …
WebApr 26, 2014 · The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction. WebNov 5, 2013 · The groove in the enzyme and the special amino acids work together to form what is called the “active site.” The active site of every enzyme is different, but each active site has a unique shape that makes it easy to hold whatever molecule is being worked on and a special set of amino acids to actually do the work.
