What is the basis for the delay between the atrial and ventricular contractions in a normal heart?
earnstyle [38]

The main responsible for the delay among the atrial and ventricular contractions is the action potential conduction velocity of the AV node cells. If the atria and ventricles contract simultaneously, atria cannot give any help in filling the ventricles, which is needed, especially in those with stiff ventricles as in the elderly. Hence atria have to contract first and then the ventricles.

Leni [432]

Bright cherry red color is produced upon the addition of methyl red indicator to a culture of a Gram negative bacilli in MR-VP broth if the organism used the mixed acid pathway of fermentation.

What is MR-VP test?

  • As part of the IMViC testing, Methyl Red (MR) and Voges-Proskauer (VP) broth is utilized as the medium in which both the Methyl Red and Voges-Prosakuer tests can be conducted.
  • It is a straightforward broth made up of dextrose or glucose, buffers, and peptone.
  • In the Methyl Red test, an infected tube of MR-VP broth is mixed with the pH indicator methyl red.
  • The acids will overwhelm the buffers in the medium and create an acidic environment if the organism employs the mixed acid fermentation pathway and creates stable acidic end products.
  • If acidic end products are present when methyl red is introduced, the methyl red will remain red.
