degradative; during the fasted state
Glycogenesis is a ____ process that occurs primarily ____
synthetic; following a meal
Lipolysis is a ____ process that occurs primarily ____
degradative; during the fasted state
Gluconeogenesis is a ______ process that occurs primarily ______
synthetic; during the fasted state
______ reduces blood glucose levels.
-glycogenesis
-Lipogenesis
______ increases or returns blood glucose to the steady state level.
-Glycogenolysis
-Gluconeogenesis
Which cells require the presence of insulin before glucose can be transported across the cell membrane?
-Muscle cells
-Adipose tissue
-Most other cells of the body
What cells in the pancreas are responsible for detecting changes (both increases and decreases) in blood glucose levels?
Beta
Insulin
-Activates glucose transporter molecules
-Decreases blood glucose levels
-Release is stimulated by increased blood glucose levels
-is released from beta cells in the pancreas
Which of these metabolic processes are stimulated by or require the presence of insulin?
-glycogenesis
-lipogenesis
Glucagon
-Increase blood glucose levels
-Release is stimulated by decreased blood glucose levels
-Is released from alpha cells in the pancreas
Which of these metabolic processes are stimulated by glucagon in the liver?
-Glycogenolysis
-Gluconeogenesis
Only glucagon is released during fasting and only insulin is released following a meal.
FALSE
Blood glucose is elevated following a glucose load.
TRUE
Blood glucose levels in the normal subject do not return to fasting levels until five hours following a glucose load.
FALSE
By about three hours following a glucose load the blood glucose has returned to its fasting level in a normal subject.
TRUE
It takes longer for a diabetic patient blood glucose to return to normal than it does for a normal subject.
TRUE
Glucose can be found in the urine if blood glucose levels are greater than 180 mg%.
TRUE
Normal fasting blood glucose can be as high as 125 mg%
FALSE
