What is an example of an antagonistic interaction?

What is an example of an antagonistic interaction?

An example is pesticide and fertilizer. Antagonistic interaction means that the effect of two chemicals is actually less than the sum of the effect of the two drugs taken independently of each other. This is because the second chemical increases the excretion of the first, or even directly blocks its toxic actions.

What is the difference between antagonistic and synergistic?

Thus, synergism is used to define a cumulative effect of multiple stressors that are greater than the additive sum of effects produced by the stressors acting in isolation; this contrasts with the term “antagonism,” used to define a cumulative effect that is less than additive (Hay et al. 1994; Hay 1996; Folt et al.

What is the difference between an antagonistic and synergistic antibiotic interaction?

The interaction between two drugs is synergistic if the joint effect of the drugs is stronger than an additive expectation and is antagonistic if it is weaker [3, 4] (Figure 1). Suppression is an extreme kind of antagonism in which one drug alleviates the effect of the other (Figure 1).

What are synergistic interactions?

Synergistic interactions occur when the combined effect of two drugs is greater than the sum of each drug’s individual activity (Cokol et al., 2011; Kalan and Wright, 2011).

What are antagonistic interactions?

In biology, antagonism is an interaction between organisms so that one organism benefits at the expense of another, like your little brother or sister benefiting by pestering you while you study. You yell at them and then get in trouble for yelling, while they look like the innocent victim and gain favor.

What are examples of antagonists?

• Mr.
• The wolf is the antagonist in “The Three Little Pigs.”
• MacDuff is an antagonist of Macbeth in Macbeth.

What is an example of synergism?

What are examples of synergism? There are various examples including: (a) Carbon tetrachloride and ethanol (ethyl alcohol) are individually toxic to the liver, but together they produce much more liver injury than the sum of their individual effects on the liver.

What is antagonistic behavior?

An antagonistic personality can be defined by traits such as narcissism, impulsivity and callousness. Someone who displays these traits is primarily concerned with their own self-interests and is more likely to manipulate and exploit others to achieve their goals.

When medicines work together in a positive way?

An additive interaction occurs when medicines work together in a positive way. 13. A synergistic effect is the interaction of two or more medicines that results in a greater effect than when the medicines are taken alone.

What are the three types of antagonistic species interactions?

Predation, herbivory, and parasitism are specific types of antagonistic interactions.

What is difference between additive and synergistic?

Synergistic effects contrast with additive effects—where the effect of two or more substances used together is equal to the sum of those substances used separately, and with antagonism—where the effect of two or more substances used together is less than the effect of the two substances used separately.

What is the synergistic effect?

synergistic effect. An effect arising between two or more agents, entities, factors, or substances that produces an effect greater than the sum of their individual effects.

What is synergistic interaction?

Synergistic interaction means that the effect of two chemicals taken together is greater than the sum of their separate effect at the same doses. An example is pesticide and fertilizer. Antagonistic interaction means that the effect of two chemicals is actually less than the sum of the effect…
