Multimedia. Water boils in a flask, and later the flask is
stoppered and removed from the hot plate. When ice
water is poured over the flask, the water begins to boil.
When the flask is cooled, the pressure of the water
vapor decreases, which decreases the boiling point of
the water.
The correct answer is: B) binding to their substrate
The catalytic mechanism of an enzyme starts when the substrate binds to its active site (specific region of an enzyme). There is a theory (lock and key) that explains the mechanism of this binding: the lock is the enzyme and the key is the substrate and only if they fit the enzyme will work. The binding of the substrate to the enzyme causes conformational changes of the enzyme, and as a result, products are formed. The products are then released from the surface of tat enzyme. The enzyme is regenerated for another reaction cycle.
To be honest I don’t really know
