In 1949-:Dr. Rachmiel Levine, introduced the theory that the greater the amount of glucose present in the blood, the more the amount that is used by the body he theorized that insulin stimulates the transport of glucose from blood to fat/muscle cells and thus lowers blood glucose level. He gave the dogs a form of sugar called galactose and found that galactose was concentrated only in small amount of water outside the cells until he injected insulin then the sugar’s dilution level showed that galactose had reached the inside of the cells his results showed that insulin was like a key that unlocked the cell membrane, allowing the sugars to get inside.
