WebApr 1, 2024 · Glucose is transported by GLUT4 (a glucose transporter protein) to the plasma membrane of a muscle cell. The hormone insulin on the outside of the cell binds to a receptor on the plasma membrane that sends a signal to increase the amount of GLUT4 on the surface of the cell. WebFeb 6, 2011 · membrane, change conformation and release glucose on the other side of the membrane. Which way the glucose goes (in or out) depends on the relative concentrations of glucose on the two sides of the respective membrane, not on (See problem 2-12 C.) f. SGLT proteins are responsible for active transport of glucose.

WebThe number of ATP molecules generated from the catabolism of glucose varies. 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. WebGlucose is transported across the cell membrane by specific saturable transport system, which includes two types of glucose transporters: 1) sodium dependent glucose transporters (SGLTs) which transport glucose against its concentration gradient and 2) sodium independent glucose transporters (GLUTs), which transport glucose by facilitative …

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.
