    Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator

    Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

    Diffusion across Biological Membranes: A simulation Introduction Diffusion is the process by which collisions between molecules cause to spread apart. This movement is described as movement from an area of greater concentration to an area of lower concentration. Hence‚ diffusion continues until the molecules are equally distributed. This is to ensure that molecules have reached a state of equilibrium. Diffusion occurs spontaneously‚ no energy is involved. In cells‚ Diffusion occurs through
