WebWhich of the following best describes the lock and key theory of enzyme action? [A] The substrate is the “lock” into which the enzyme, or the “key,” fits. [B] The enzyme and substrate have identical shapes, like a “lock and key.” [C] Once the enzyme and … WebA Lock and Key analogy may be used to describe the fundamental action of a single substrate enzyme. In this case, the enzyme is the lock, and the substrate is the key. Only the correct size key, which is the substrate, enters the keyhole, which is the active site of the lock, which is the enzyme. Other keys that are too tiny, too big, or have ...

WebEnzymes are highly specific. They must bind to a specific substrate before they can catalyze a chemical reaction. In this case, the enzyme is the lock, and the substrate is the key. Only the correct size key, which is the substrate, enters the keyhole, which is the active site of the lock, which is the enzyme.

WebJan 21, 2014 · The enzyme-substrate binding causes reorientation of the structure of site due to in a strain condition. Thus transitional state is required and here bond is unstable and eventually broken. In this way bond between substrate is broken and converted into products. 30. LOCK AND KEY MODEL Proposed by EMIL FISCHER in 1894. WebLock–key model, or its modified version, the induced-fit model [ 21 ], explains catalysis by an enzyme with an easily accessible active site, while it is less appropriate for the enzymes with active sites buried in the protein core. The activity and specificity of such proteins is determined by not only the geometry and properties of the ...

(a) Because the substrate and the active site of the enzyme have complementary structures and bonding groups, they fit together as a key fits a lock. (b) The … WebExplanation: . The lock and key model states that the active site of an enzyme precisely fits a specific substrate. The induced fit model states that the active site of an enzyme will undergo a conformational change when binding a substrate, to improve the fit.
