Anita AkweshieA2 Negative Feedback Control of Blood Glucose
CIE Syllabus
-
how is the blood glucose concentration regulated
by negative feedback control mechanisms
-
what is the process in negative feedback systems
receptors detect whether a specific level is too low or too high
information is communicated through the hormonal or nervous system to effectors
effectors react to counteract the change by bringing the level back to normal
-
what is the NFM process in control of BGC
alpha and beta cells in the pancreas act as the receptors
they release the hormones glucagon from alpha cells and insulin from beta cells
liver cells, muscle cells and fat cells are the effectors
-
what are the effectors activated in response to insulin
liver ,muscle and fat cells
-
what is the effector activated in response to glucagon
liver cells
