SGLT proteins are responsible for active transport of glucose. WebMar 6, 2024 · Through GLUT 1, glucose enters and passes through it via facilitated diffusion at a rate that is 50,000 higher than in its absence. GLUTs of various types are found in different cells of the body. The one in red blood cells is known as GLUT 1 and has 12 membrane-spanning hydrophobic helices. WebTo move glucose from the digestive tract, where it is located after a meal, into the body cells, where it's utilized, the glucose has to cross several cell membranes.

For example, the number of hydrogen ions that the electron transport chain complexes can pump through the membrane varies between species. Another source of variance stems from the shuttle of electrons across the membranes of the mitochondria.

WebDec 30, 2016 · Interestingly, just like one may get to work both by bus and by driving, it has been found recently that some gas molecules may have more than one way to cross the membrane, i.e., besides diffusion through lipids, oxygen and carbon dioxide may also pass through AQPs. However, the pathways that these gas molecules take remained elusive. WebLarger molecules such as glucose require a specific transport protein to facilitate their movement across the cell membrane.
