Testosterone, a type of lipid known as a steroid, is moving along its concentration gradient. Determine and describe the specific type of membrane transport that will move testosterone into the cell

What will be an ideal response?


Simple diffusion, a specific type of passive transport, is the process by which testosterone will move along its concentration gradient into the cell. Lipids, such as testosterone, are agreeable to the nonpolar fatty acid tail region of the phospholipid bilayer. No energy is expended by the cell to move testosterone with its concentration gradient.
