Carrier proteins such as the glucose transporter GLUT

Question

Quizplus · Accepted Answer

Carrier proteins, such as GLUT, undergo significant conformational change during transport, allowing them to move substances across the membrane. This is different from channel proteins, which remain open to both sides of the membrane at the same time and provide high resistance passage for substances to cross. The directionality of transport depends on the carrier protein and the concentration gradient of the substance being transported, so D is not always true.
