Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.
Answer:
A
Explanation:
I'm not completley sure but veins go to every location in your body while capillaries and arteries are in designated areas.
OK well first of all I hate biology but I like writing so you can use :: The molecular reactions of cellular respiration transform Krebs cycle into the more readily available bond energy of ATP.
Answer:
Myosin
Explanation:
Two of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament. Myosin has a long, fibrous tail and a globular head, which binds to actin. The myosin head also binds to ATP, which is the source of energy for muscle movement
