Is he taking any drugs for sexual enhancement or erectile dysfunction!?!?
Nitroglycerin is a vasodilator, which means that it relaxes and dilates (widens) blood vessels; this is a positive effect for coronary arteries, whose narrowing and/or occlusion (blockage) may be the cause of [cardiac] chest pain.
But, other vessels throughout the body also dilate, which can be good in hypertension.
However, a specific class of drugs known as phosphodiesterase-5 inhibitors (PDE-5-I), which includes sex-enhancing drugs for erectile dysfunction (ED), will irreversibly keep body vessels dilated when nitroglycerin is also present in the bloodstream. This can lead to a life-threatening pooling of blood of the arms and legs (extremities) and lower body, keeping adequate blood from reaching the heart, lungs, and brain. This emergency is known as vasogenic shock!
Examples of PDE-5 inhibitors are Viagra, Levitra, and Cialis. [generic names of this class are: vardenafil, sildenafil, tadalafil and avanafil]
If these are the choices:
The ability to halt the cell cycle in response to DNA damage.
The ability to halt the cell cycle in response to the chromosomes not properly aligning on the metaphase plate.
The ability to repair DNA damage.
The ability to activate Cdks.
The ability to stimulate cell death processes if the cell is irreparably damaged.

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>

this is true. when it is warmer the plant and insects can migrate to these other places so they do not have to die or hibernate through winter
