Symporters are integral membrane proteins that control the entry and exit of a specific type of molecule across the cell membrane in a mode that is dependent on the transport of a second specific type of molecule in the same direction. Symporters are membrane cotransporter proteins involved in active transport, i.e.., they require energy (usually in the form of ATP) to transport substances in the same direction. The Sodium (Na+)-Dependent Glucose Transporter 1 (SGLT1) is a cotransporter involved in the transport of glucose across cell membranes of enterocyte intestinal absorptive cells. For such purpose, SGLT1 contains two Na+-binding site sites, one of them overlapping the glucose-binding site. It has been shown that mutations at the glucose-binding site may alter the ability of SGLT1 to transport glucose.
a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
The factors that affect temperature or altitude latitude and distance from sea the height measured from sea level is called altitude when the latitude increases the distance from the Sun Also increases so the temperature gradually decreases
