Randy was given a prescription for an antidepressant. his psychiatrist also gave him a long list of foods to avoid and warned ra
Arturiano [62]

The correct answer is: MAO inhibitors.

MAOI - monoamine oxidase inhibitors are antidepressants that affect the enzyme called monoamine oxidase which normally removes the neurotransmitters norepinephrine, serotonin and dopamine from the brain. As a consequence, neurotransmitter’s activity is increased. MAOIs interact with tyramine, amino acid found in food such as cheese, smoked sausage, and red wine. Tyramin eis normally regulated via MAO. So, when the MAO is inhibited via MAOI, tyramine reaches high levels, causing the blood vessels to narrow and resulting in critically high blood pressure.

How do carbons bonding properties contribute to the existence of a wide variety of biological molecules?
ICE Princess25 [194]
<span>Because of the location of its valence electrons, a C atom can bond in four places, rather than 1 or 2 like most elements. This allows for many different arrangements.</span>

How do the nervous system and endocrine system work together? apex?
jek_recluse [69]
The nervous and the endocrine system are tightly linked together.
The main reason for this linkage is due to the connection of the hypothalamus (nervous system) and the hypophysis (a gland in the endocrine system)
The hypophysis is the ''controller'' of all of the other endocrine glands.
The connection between the hypothalamus and the hypophysis enables the nervous system to control the hormone levels of all of the major endocrine glands in the body.
The hypothalamus releases hormones into the bloodstream that leads to the hypophysis. These hormones induce a release of hypophysis hormones that enter the bloodstream and when they reach the target gland (for example pancreas) these hormones induce the release of the hormones of that gland (in the case of the pancreas, insulin).
The hypothalamus monitors the concentration of hormones in the blood, and a high level of a certain hormone blocks the release of the hypothalamus' hormones. Therefore, a high level of insulin blocks a cascade of hormone release that starts in the hypothalamus that leads to its release in the pancreas.

Why don't all thermodynamically favored reactions occur rapidly?
serg [7]

solution:

Thermodynamically favorable reaction is the products, because the reaction occurs spontaneously, without the need for energy to be added.

Because a reaction is thermodynamically favoured does not mean that it will be a fast reaction. So 'yes' they always proceed but possibly infinitesimally slowly. Temperature is the most common way of quickening a reaction. Of course a catalyst also does so but this generally by changing the way the reaction occurs, i.e. the mechanism is different using a catalyst but the product is the same. Enzymes are natures catalysts, in synthetic chemistry (and in you car exhaust) metal based compounds are often used.

All reactions have an activation energy EaEa between reactants and products and a small increase in the size of this can slow a reaction exponentially. Experimentally, the rate constant is generally found be of the form k=k0exp(−Ea/RT)k=k0exp(−Ea/RT), which is the Arrhenius equation, with R the gas constant and T the temperature in Kelvin .

Name two qualities of the heartbeat that must be observed
Natasha_Volkova [10]

Answer;

-Volumen, and

- Rhythm

Explanation;

-Volumen refers to the force or strengh of the pulse terms are normal full, bounding weak or theady.

-Rhythm refers to the regularity of spacing between beats. terms are regular, irregular, regularly irregularly and intermittent.  Heart rhythm is vital to the function of the heart. If the heart fails to be excited, then no beating occurs.

-A normal heart rate is usually stated as 60 to 100 beats per minute. Slower than 60 is called bradycardia; faster than 100 is tachycardia ("fast heart").
