<p>Structure and function of enzymes = Relates to the specific shape and role of biological catalysts The effect of pH and temperature on enzyme action = Influences the activity of biological catalysts Diffusion = The movement of molecules from an area of high concentration to an area of low concentration Osmosis = The movement of solvent molecules across a selectively permeable membrane</p> Signup and view all the answers

<p>Active transport = Movement of molecules across a cell membrane using energy Enzymes = Biological catalysts that speed up chemical reactions Diffusion = Passive movement of molecules from high to low concentration Osmosis = Passive movement of solvent molecules across a semi-permeable membrane</p> Signup and view all the answers
