absorption and glucose regulation Flashcards
the self regulating process by which living systems maintain stability
homeostasis
three examples of homestasis
blood glucose, body temperature and blood calcium levels
what do endocrine glands secrete in the endocrine system
hormones
what do hormones do to target organs in the endocrine system
they cause the function of that organ to speed up, slow down or alter in some way
what is the main role of glucose in the animal body
glucose is needed by cells for respiration
what is the endocrine function
secretes hormones into the bloodstream
what are the two types of cell that the islets of langerhans contain
- a-cells (alpha cells):produce glucagon
- b-cells (beta cells):produce insulin
the formation of new glucose molecules in the body as opposed to glucose that is broken down from the long storage molecule glycogen
gluconeogenesis
the biological process of forming glycogen from glucose, the simplest cellular sugar
glycogenesis
the metabolic pathway that converts glucose into pyruvate molecules
glycolysis
the activity of absorbing or integrating substances within a cell
cellular absorption
