Molecules which are transported across the membrane against their concentration gradient, i.e. from the lower to the higher concentration. Such a transport is called active transport, e.g., Na^(+)/K^(+) pump.
Why is it important for cells to be able to use both active and passive transport to transport molecules across the cell membrane? Active and Passive Transport: Passive transport occurs when substances move down a concentration gradient from a h...

S1B-S1D). We fused these CAR-293T cell membrane patches with Jurkat cells at 37 °C using the fusion agent PEG1450. We initially assessed their ability of fused-CAR-T cells to target EpCAM-positive cells. Results indicated that the group of fused-CAR-T cells exhibited superior targeting...

The small intestine is among the fastest self-renewing tissues in adult mammals. This rapid turnover is fueled by the intestinal stem cells residing in the intestinal crypt. Wnt signaling plays a pivotal role in regulating intestinal stem cell renewal an
What structures in the cell membrane function as ion channels? What does a cell membrane do? What is the cell membrane also called? Which type of cell, if any, does not have a plasma membrane? Which molecules need facilitated diffusion to move across the plasma membrane? What are...
