PPT-Active Transport of molecules

Active Transport Driven by ATP Hydrolysis The net flow of molecules by facilitated diffusion through either carrier proteins or channel proteins is always energetically downhill in the direction determined by electrochemical gradients across the membrane . Have you taken the latest quiz?. When is your next paper due?. If you are not sure, you need to. Plasma Membrane: the bouncer. (controls who gets in and who leaves). The plasma membrane. phospholipid bilayer. Name the organelle that performs each function:. Creates ATP from other compounds. Tags and packages other molecules. Conducts photosynthesis. Contains DNA and controls the cell. A cell is eukaryotic, and has a cell wall and chloroplasts. What kind of cell is it?. Chapter 2.2. McGraw-Hill Ryerson. Biology 12. (2011). Concentration gradient.
