Biochemical and metabolic changes occur in hibernating bears and signaling pathways and regulations involved should be discussed. Concept Introduction: Hibernation is state of inactivity and metabolic depression under extreme conditions. It can be observed mostly in winter season. Hibernation is used to conserve energy when sufficient food is not available. To achieve this some animals decrease their metabolic rate and hence the body temperature. Before the hibernation period, animals need to store enough energy to pass the dormant period. Hibernating bears are capable of recycling proteins and urine without eating, drinking, urinating or defecating for entire winter season.

Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
