Active transport: primary & secondary overview (article)

WebThere are two mechanisms for glucose transport across cell membranes. In the intestine and renal proximal tubule, glucose is transported against a concentration gradient by a secondary active transport mechanism in which glucose is cotransported with sodium ions. In all other cells, glucose transport is mediated by one or more of the members of ...

WebTo bring glucose into the cell requires some amount of energy. 4. To bring glucose from the blood to the cell, a basolateral glucose channel will allow glucose to move down its gradient. An apical sodium/glucose antiporter will move glucose against its gradient by using the energy of sodium following its gradient. WebNov 16, 2024 · Because glucose is a large molecule, its diffusion across a membrane can be difficult. As a result, it diffuses across membranes by facilitating diffusion, resulting in a …

WebLarger molecules such as glucose require a specific transport protein to facilitate their movement across the cell membrane. Very large molecules such as proteins are too big … WebMay 14, 2024 · Molecules and ions move spontaneously down their concentration gradient (i.e., from a region of higher to a region of lower concentration) by diffusion. Molecules and ions can be moved against their concentration gradient, but this process, called active transport, requires the expenditure of energy (usually from ATP). 2.
