Active transport - Wikipedia, the free encyclopedia

Examples of active transport include the uptake of glucose in the intestines in Hydrolysis of the bound phosphate group and release of hydrogen ion then.

Crane 's discovery of cotransport was the first ever proposal of flux coupling in biology. In August 1960, in Prague, Robert K. Crane presented for the first time his discovery of the sodium-glucose cotransport as the mechanism for intestinal glucose absorption.

ATP hydrolysis is used to transport hydrogen ions against the electrochemical gradient (from low to high hydrogen ion concentration). Phosphorylation of the carrier protein and the binding of a hydrogen ion induce a conformational (shape) change that drives the hydrogen ions to transport against the electrochemical gradient.

Biological Membranes and Membrane Transport Mechanisms

Examples of various membrane transport mechanisms.. SLC37A4 is also known as glucose-6-phosphate transporter-1 (G6PT1) which is defective in glycogen.

In general these transporters are referred to as ATPases. In contrast, active transporters transport specific molecules from an area of low concentration to that of high concentration. These ATPases are so named because they are autophosphorylated by ATP during the transport process. There are many different classes of transporters that couple the hydrolysis of ATP to the transport of specific molecules. hydrolysis of ATP. Because this process is thermodynamically unfavorable, the process must be coupled an exergonic process, e.g.
