How do the control mechanisms in glycogen metabolism lead to amplification of response to a stimulus?
Molodets [167]
<h2>Glycogen </h2>

Explanation:

  • This is based on the fact that the response to hormones generates a signaling cascade that eventuates in the activation or inhibition of enzymes involved in glycogen metabolism
  • The benefit of a multi-step cascade is that it amplifies the signal which means that response can be fast and significant
  • High level of secondary messenger, cyclic adenosine monophosphate (cAMP)  activates a protein called protein kinase A (pKA) which phosphorylates phosphorylase kinase (pK) and activates it
  • On the other hand at the same time pKA phosphorylates glycogen synthase and inactivate it
  • pK becomes active that phosphorylates glycogen phosphorylase and makes it active, glycogen phosphorylase catalyse breakdown of glycogen (in liver and muscle cells)
  • Activated protein kinase A enters in nucleus and phosphorylate a transcriptional activator called cyclic AMP response element binding protein (CREB)
  • Phosphorylated CREB becomes active and binds to a DNA element called cyclic AMP response element (CRE) and induce transcription of various genes which involved in glucose metabolism

Mammalian red blood cells are biconcave which increases the amount of surface area through which oxygen can diffuse. this is an
Liula [17]
Mammalian red blood cells contain hemoglobin as its primary unit for oxygen and carbon dioxide transportation. In order to increase the efficiency of transport (increase the amount of oxygen and carbon dioxide transported per red blood cell), the red blood cells' structure are designed to be biconcave. This efficient structure of the red blood cells increases it function compared to a spherical red blood cell (low surface area, i.e. hereditary spherocytosis). <span>This is an example of the relationship between structure and function of the red blood cells. </span>Also, the biconcave shape of the red blood cell makes it more resilient to early destruction in the small capillaries and the spleen (since the spleen is mostly responsible for red blood cell turnover, which is every 120 days).
