Question: Which pituitary hormone causes liver cells to release somatomedins that increase the rate of uptake of amino acids by cells such as skeletal muscle fibers?
follicle-stimulating hormone
prolactin
thyroid-stimulating hormone
growth hormone
Answer:
growth hormone
Explanation:
Somatomedins are growth factors. The growth hormone makes the cells such as liver cells, skeletal muscles, bones, etc. to secrete the somatomedins. The somatomedins from the liver enter the bloodstream to reach the target cells. The somatomedins make the skeletal muscles, bones, etc. to absorb amino acids into the cells so as to facilitate protein synthesis. This growth factor also downregulates the breakdown of proteins. This is how growth hormone triggers the growth of muscles and soft tissues.
