Which of the following is true regarding phase 3 of action potential?

Medicine
1 answer:
s344n2d4d5 [400]3 years ago
8 0

Answer:

calcium channel close.

Explanation:

In action potential there is phase 0, phase 1, phase 2, phase 3 and phase 4. In phase 3 of action potential there is a rapid repolarization phase in which calcium channels remain closed but potassium channels remain open and continuous outward movement or leakage of positive ions causes the outside environment positive and membrane potential goes to negative charge that is -85mV to -90mV

The mechanism under the therapeutio effect of lovastatin is:
Ilya [14]

Answer:

(B). inhibiting HMG-CoA reductase.

Explanation:

Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.

It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.

Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.

Thus, the correct answer is option (B).

Whats the best procedure to deal with corrosive substances that have been ingested milk or mineral oil?
My name is Ann [436]

The answer is Ingested corrosives may be diluted by drinking 4–6 oz (113.4–170.1 ml) of water or milk. If vomiting is persistent, do no attempt to administer additional fluids. Avoid neutralization therapies as the resultant exothermic reaction may cause additional tissue injury.

Explanation :

  • Strong acids, corrosive agents, and highly reactive oxidants can cause large-scale destruction of living cells through direct chemical reactions. Sometimes referred to as necrotic cell death, this non-specific effect is induced by concentrated solutions of caustic and caustic chemicals that cause indiscriminate cell destruction.
  • A generalized overwhelming effect of this type is no different from those resulting from "burning" tissue. These chemically induced injuries are commonly referred to as "chemical burns."  
  • Such effects are produced not only by strong acids or bases  in harmful concentrations, but also by exposure to concentrated solutions of organic solvents such as ether, chloroform or carbon tetrachloride. The intensity of such non-specific toxicity is directly related to the concentrations of the chemical agents when  in contact with the target tissues.
  • Widespread cell destruction  can be caused by any chemical that is sufficiently soluble in tissue fluids to  access  cells at high concentrations. The effects of these chemicals in higher organisms are generally limited to easily accessible tissues such as the skin, eyes, mouth, nasal mucosa, and respiratory tract.
