Part A Match the worts in thecrase ydro es sucrose but How would the lock-and-key model explain that sucrase hydrolyzes sucrose, but not lactose? Match the words in the left column to the approprsate blanks in the sentences on the right. O Sucrose has a CH2OH group which binds to the actve ste in sucrase, but lactose has not. Sucrose can adjust ts shape to fit the shape of the active site in sucrase, but lactose cannot O Sucrose has a carbonyl group which binds to the actve ste in sucrase, but lactose has not O Sucrose fhs the shape of the active ste in sucrase, but lactose does not Submit My Answers Give Up

Explanation / Answer

1.How is the active site different from the whole enzyme structure?

Active site : It is the part of a catalyst that straightforwardly ties to a substrate and conveys a response. It contains synergist bunches which are amino acids that advance arrangement and corruption of bonds. By shaping and breaking these securities, chemical and substrate cooperation advances the arrangement of the move state structure.

Catalysts help a response by settling the move state middle of the road. This is expert by bringing down the vitality hindrance or actuation vitality the vitality that is required to advance the development of move state middle. The three dimensional separated is shaped by the gatherings that originate from various part of the amino corrosive arrangements. The dynamic site is just a little part of the aggregate chemical volume. It improves the chemical to tie to substrate and catalysis by a wide range of powerless collaborations due to its nonpolar microenvironment. The powerless cooperations incorporates the Van der Waals, hydrogen holding, and electrostatic connections. The course of action of particles in the dynamic site is pivotal for restricting spectificity. The general result is the speeding up of the response procedure and expanding the rate of response. Besides, do catalysts contain synergist capacities, as well as conveys the acknowledgment of substrate.

2.Why do most enzyme-catalyzed reactions go fast?

most enzyme-catalyzed reactions go fast by lowering the activation energy of reactants

3. 3.How would the lock-in key model explain that sucrase hydrolyzed sucrose , but not lactose?

According to lock-in key model ,

During hydrolysis

Sucrose fits the shape of the active site in sucrose ,

While

Sucrose does not does fits the shape of the active site in lactose .

Option B
