InsulinMultiple Choicehelps glucose enter cells.increases blood glucose levels after meals.stimulates cells to break down glycogen for energy.is released during fasting periods, such as between meals.

Upon entry of meal in the digestive system there is secretion of insulin increases to promote the cellular uptake and storage of ingested nutrients. Which of the following mechanism is responsible for this event:Select one:a. Negative feedbackb. Adaptivec. Feed forwardd. Positive feedbackClear my choice

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

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.

Why do you think fasting might be necessary?Group of answer choicesFoods with high levels of fat will block digestion of sugars.Eating foods high in protein can cause glucose levels to increase.Other food or drink that contains sugars can increase blood glucose levels regardless of whether they produce lactase.You need to have an empty stomach in order to drink one liter of milk.

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.
