Why is the protein channel in Model 3 called a "gated" channel? Channel acts like a gate; when the hormone insulin binds with the protein, it acts like a key that opens the locked gate, allowing the glucose sugar t pass through. Why is diffusion called "facilitated" diffusion? Glucose needs help from the hormone insulin, which causes the channel to widen. The process is still diffusion because the glucose moves from an area of higher to lower concentration. Which part of the cell membrane is shown in more detail in Model 4? Membrane-spanning channel proteins. What shape represents the substance being transported across the membrane in Model 4? Diamond List two binding sites found on the protein. Ion and ATP binding sites In which direction is the transported substance moving-from an area of high concentration to low or from an area of low concentration to high?
