gHow would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would reduce cAMP levels and inhibit
Ksivusya [100]
<h2>cAMP and glucose mobilization</h2>

Explanation:

It would maintain high cAMP level and elevate glucose mobilization

  • Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
  • Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
  • As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
  • Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
  • In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood

As mean arterial pressure increases, the ________, informing the medulla oblongata that blood pressure has indeed increased.
finlep [7]

As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.

  • Special receptors called baroreceptors monitor variations in your blood pressure.
  • The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
  • Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
  • The brain interprets the information that the baroreceptors send as a rise in blood pressure.
  • The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.
