Flame cells are scattered throughout parenchyma from which they remove metabolic wastes. A flame cell is of irregular shape, with granular cytoplasm and a nucleus. Bundle of cilia, or flame, arises from basal granules near nucleus. Cilia are enclosed into a funnel-shaped lumen formed by the terminal blind end of a capillary. Protonephridia are found in flatworms, Malpighian tubules in insects and green glands in crustaceans.

Briefly outline the signal transduction steps and enzymatic events involved in glucagon's action on stored materials in the muscle. Glucagon plays a crucial role in regulating glucose levels in the body, particularly in the liver and muscle tissues. When blood glucose levels are low, glucagon is released by the pancreas to stimulate the breakdown of stored materials, such as glycogen, in the muscle. The signal transduction pathway initiated by glucagon begins with the binding of glucagon to its receptor on the surface of muscle cells. This binding activates the receptor, leading to the activation of a G protein, specifically the Gs protein. The activated Gs protein then stimulates the production of cyclic adenosine monophosphate (cAMP) from adenosine triphosphate (ATP) through the activation of adenylyl cyclase. The increase in cAMP levels triggers the activation of protein kinase A (PKA), which is a key enzyme involved in glucagon signaling. PKA phosphorylates and activates several downstream targets, including phosphorylase kinase. Phosphorylase kinase, in turn, phosphorylates and activates glycogen phosphorylase. Glycogen phosphorylase is the enzyme responsible for the breakdown of glycogen into glucose-1-phosphate. Once activated, glycogen phosphorylase cleaves glucose units from the glycogen polymer, releasing glucose-1-phosphate. This glucose-1-phosphate can then be further converted into glucose-6-phosphate and enter glycolysis for energy production. In addition to the activation of glycogen phosphorylase, glucagon also inhibits glycogen synthase, the enzyme responsible for glycogen synthesis. This inhibition prevents the synthesis of new glycogen molecules, further promoting the breakdown of stored glycogen. Overall, glucagon's action on stored materials in the muscle involves a signal transduction pathway that activates protein kinase A and phosphorylase kinase, leading to the activation of glycogen phosphorylase and the breakdown of glycogen into glucose-1-phosphate.
