Question

Chapter 3: The Cellular Level of Organization (membrane transport only) 1. Passive Transport Across a Cell Membrane a. Diffusion of molecules across a cell membrane is passive and influenced by concentration (chemical) gradient. This means that molecules moves passively from an area of high / low (circle one) concentration to an area of high / low (circle one) concentration. This does not require ATP. b. What kind of molecules can diffuse directly through the phospholipid bilayer? c. Some molecules require a protein channel to diffuse through the phospholipid bilayer. This is called facilitated diffusion. What type of molecules require a protein channel? 2. Osmosis a. Osmosis is a type of facilitated diffusion, but specific to what molecule? b. The name of the protein channels which allow water to pass through a cell membrane down water's concentration gradient are c. If a cell is placed in a solution that is hypertonic to the intracellular fluid (ICF), the cell will: gain water or lose water? 3. Active Transport Across a Cell Membrane a. Active transport of molecules across a cell membrane occurs when molecules move y from an area of high / low (circle one) concentration to an area of high / low (circle one) concentration. This requires a protein channel and also requires .
