Antagonsitic effect/interaction/response

In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest. 

First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.

The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect. 

Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.

Alika [10]
<h2>Answer:</h2>

If you go a bit overboard and feel a sudden pinch and you start bleeding, It means that something penetrate in your skin and torn off your blood vessel so that you start bleeding.

May be there was any pin or sharp needle thing was there in board that pinch into your skin and your epidermis could not resist that and it is no longer intact and you created a wound on your skin.

Epidermis the surface epithelium of the skin of an animal, overlying the dermis. and in this case it is wounded by that pin.

puteri [66]

Answer:

The tiles can be arranged as follows:

  • make an observation
  • ask questions
  • construct a hypothesis
  • test the hypothesis
  •  analyze the results and make conclusions
  • communicate the result

Explanation

A scientific investigation begins with certain observations. By seeing these observations, a question is made. To answer the question, a hypothesis is generated. A hypothesis is a tentative statement that can either be stated s correct or wrong. To test the hypothesis, experiments are made and results are deduced from the experiments. Based on these results, a hypothesis can be proved as correct or wrong. These results are then communicated to check for their authenticity.

Why is it essential that the regulatory mechanisms that activate glycogen synthesis also deactivate glycogen phosphorylase?
Marta_Voda [28]

Answer:

There are two pathways occur in the same cellular compartment, and, if both are on at the same time, a futile ATP hydrolysis cycle results. Using the same mechanism to turn them on/off or off/on is highly efficient.

- "Glycogen Phosphorylase" activity can be allosterically controlled ATP and G6P allosteric inhibitors, AMP allosteric activator as well as, controlled through covalent modification, phosphorylation and via hormones.

- Reaction Catalyzed by Glycogen Synthase:

The activity of glycogen synthase is subject to the same type of covalent modification as glycogen phosphorylase, however, the response is opposite. Glycogen Synthase is activated by G6P. It is also controlled via hormones.

Have afib and now have been diagnosed with left bundle branch block no cardiac artery disease
GrogVix [38]
Well... I get the felling I know what question you are trying to ask. Atrial Fibrillation is a type of arrhythmia that interferes with the pumping of blood through the Atrium of the heart. A bundle branch block is an interference of the electrical system through the heart. Non of these are particularly that dangerousso don't worry about dying... Though have someone close by in case you go into Cardiac Arrest.

If your worried about getting a heart attack, that is a blood flow problem which can result from CAD. Don't worry though cause the two other condition do not particularly influence the other.

CAD is circulatory, A fib and branch block are electrical.
