Sugar uptake in muscles. Diagram showing sugar from a drink (upper right) being taken up by the muscles of the human body. The musculature of the human figure is shown,followed by an expanded view of a muscle fibre,fibril and myofibril,all the way down to the level of the muscle cell. The circular inset at lower left shows the membrane of a muscle cell,with sugar molecules (circular) passing through membrane pore (yellow) with the help of proteins called glucose transporters. The sugar is then used in biochemical reactions involving the molecule ATP (adenosine triphosphate) that powers the muscle contractions | |
