Can somebody do 4 and 5 for me

Answer:

4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.

5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.

Explanation:

4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.

5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.

pH: when the pH increases or decreases it produces a decrease in the speed of reaction that catalyzes an enzyme. Very high or low pH levels can denature the enzyme and make the expected reaction not occur.
Temperature: like pH, changes in temperature can slow or stop maltase activity.
Substrate availability: It is a fact that when the specific substrate of an enzyme becomes depleted, the rate of reaction slows down, stopping when no substrate is available.
