Membranes (both outside and inside the cell) correct answer: Not a static structure, very important for cell function. They contain proteins that are very complex and vital to cell life. Mitochondria membranes correct answer: Very vital for the cell, has both an inner and outer membrane. What drives membrane formation? correct answer: A decrease in ionic interactions with water / limiting the hydrophobic interactions drives membrane formation. Lipid tails are ... correct answer: Hyd...
