Biochemistry

A 19-year-old athlete has been vigorously working on the tracks and begins to feel slightly light-headed from hypoglycemia. He drinks a can of soft drinks and is aware of the competition for the glucose to be stored in his liver as glycogen versus used as energy in his muscles. What is the best explanation regarding the fate of the glucose in the soft drink?

The lower Km of hexokinase versus the Km of glucokinase will tilt the glucose toward glycolysis.

The bolus of glucose the soda will lead to a higher glucose level, inducing storage of the glucose into glycogen in the liver.

The muscle is using high levels of glucose, leading to an increased level of glucose 6-phosphate thus inhibiting glucokinase.

The glucose will be equally used by muscle for metabolism and liver for glycogen storage.
