To explain: The advantages of having increased levels of GLUT1 and phosphofructokinase in muscles for the adaptation in high altitudes.
Concept introduction: GLUT 1 stands for glucose transporter 1, also called as solute carrier family 2. It was the first glucose transporter to be characterized. It helps in the transport of glucose across the plasma membrane of the mammalian cells. Phosphofructokinase is an enzyme that phosphorylates fructose 6-phosphate in the glycolysis.
Explanation of Solution
The lower air pressure in the high altitudes makes it more difficult for oxygen to enter the vascular systems. Therefore, oxygen availability for the aerobic
