When insulin is released it causesGroup of answer choicesThe liver to decrease fatty acid synthesisMuscle and adipose tissue to increase glucose uptakeThe liver to decrease glucose uptakeLiver and muscle to increase glycogen breakdown

Insulin functions by facilitating the uptake of glucose by: (1 Point)a) Liver cellsb) Muscle cellsc) Fat cellsd) All of the above

In the liver, insulin signalling up-regulates glycolysis. Which of the following signalling pathways explains that mechanism?Group of answer choicesIt activates protein phosphatase-1 which dephosphorylates glycogen phosphorylase.It results in the activation of cAMP dependent protein kinase A (PKA) which phosphorylates pyruvate kinase.It activates the expression of hexokinase, PFK-1 and pyruvate kinase.It results in an increased expression of phosphoenolpyruvate carboxykinase and glucose-6-phosphatase.

When insulin is secreted, what happens?Multiple ChoiceTissue stores of glucose are depleted.Adipose tissue breaks down fat.The liver breaks down glycogen.The blood glucose level rises.Glucose is taken up by the cells.

An elevated insulin level in blood:Group of answer choicesInhibits glucose uptake by the liverStimulates synthesis of fatty acids and triacylglycerols in the liverStimulates glycogen breakdown in liverInhibits glycogen synthesis in the liver and muscle

Which of the following BEST describes the role of insulin?To regulate calcium levels in the bloodTo facilitate the uptake of glucose into cellsTo stimulate the release of growth hormoneTo increase blood sugar levels
