How does glucose diffuse through a membrane
WebApr 14, 2024 · Glucose is a six-carbon sugar that is directly metabolized by cells to provide energy. The cells along your small intestine absorb glucose along with other nutrients from the food you eat. A glucose molecule is too large to pass through a cell membrane via simple diffusion. Instead, cells assist glucose diffusion through facilitated diffusion ... Web2/8/2024 4 • At dynamic equilibrium, as many molecules cross the membrane in one direction as in the other Figure 7.11a • Substances diffuse down their concentration gradient, the region along which the density of a chemical substance increases or decreases • Each substance moves down its own concentration gradient, unaffected by the …
