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 ... WebOct 21, 2012 · Best Answer.
