Answer :D
- It stimulates the liver to convert its stores of glycogen back into glucose. This response is known as glycogenolysis. The glucose is then released into the circulation for use by body cells.
- It stimulates the liver to take up amino acids from the blood and convert them into glucose. This response is known as gluconeogenesis.

1) Create a flow chart to map out the steps of the knee jerk reflex. Include the specific stimulus, sensor, neuron types, integrating center, effector (specific muscle!), and response for knee jerk reflex Stimulus ---> Sensor ---> Afferent path ---> Integrating center ---> Efferent path ---> Effector ---> Response 2) What is the value of involuntary reflexes? That is, would it be better if we could control everything our body does? Why or why not?

Insulin and glucagon release from the pancreas is a vital part
of the negative feedback loop that regulates blood glucose levels.
Let's review how insulin and glucagon release change in response to
plasma glucose levels and how that helps keep plasma glucose
constant.
Drag the labels onto the figure to create a flow chart of how
insulin and glucagon release change in different circumstances to
keep blood glucose within a normal range.

A patient presents with a deficiency of thiamine. If this patient's liver cells are compared with normal cells, which of the following products would be decreased in the thiamine-deficient cell (when compared to the normal cells) if the cells are only given glucose as a fuel? O Alanine O co2 Lactate O NADP+ e Pyruvate A patient is newly diagnosed with a deficiency in fructokinase. Which of the following will not be a metabolic consequence...

SECTION 1: Structure of a Skeletal Muscle A. Layers of connective tissue separate a muscle into compartments. The layer called endomy- sium surrounds each muscle cell. Muscle cells are then bundled into fascicles, which are sur- rounded by perimysium. The entire muscle is composed of many fascicles, and is surround- ed by epimysium. All layers merge together to form the tendon that attaches the muscle to a bone. An outermost layer of connective tissue called fascia binds adjacent muscles together...

With the paper in a landscape orientation, place the liver in the center, the brain the upper left, adipose upper right, skeletal muscle lower left, and heart lower right.

2. During exercise, skeletal muscle generates lactate by anaerobic glycolysis. Lactate enters the blood stream and is taken up by the liver, which recycles it back to glucose through gluconeogenesis. This is known as the Cori cycle. Determine the energetic cost of maintaining glucose to the muscle by this mechanism. OPTIONS ARE: -6 -4 -2 0 +2 +4 +6 Pathway ATP generated ATP/GTP consumed Net ATP/GTP Glucose -> lactate Lactate -> glucose Net ATP/GTP
