The highest point the medium rises to and a trough is the lowest point the medium sinks to.
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 <u>hydrolysis</u> 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. <u>Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers</u>, 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. <u>Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions</u>. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.
- <em><u>pH</u></em><em>: 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.
</em>
- <em><u>Temperature</u></em><em>: like pH, changes in temperature can slow or stop maltase activity.
</em>
- <em><u>Substrate availability</u></em><em>: 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.</em>
Explanation:
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell's supply of metabolic energy may be spent maintaining these processes.
None of the above is correct.
Brain is the organ that is most sensitive to the absence of glucose in the blood. The glucose is needed by the neurons in the brain to carry out their functions. The neurons when deprived of glucose, start to slow down and die out of exhaustion. The lack of glucose can cause symptoms of hypoglycemia, wherein a person starts to experience hallucinations and suffers from excruciating pain in the joints of the bones.
