The rate at which molecules diffuse across the cell membrane is directly proportional to the concentration gradient this applies to simple diffusion, which is governed by fick's. The effect of substrate concentration on enzyme activity skip the theory and go straight to: how to determine km and vmax a simple chemical reaction with a single substrate shows a linear relationship between the rate of formation of product and the concentration of substrate, as shown.
Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.

Count the number of oxygen bubbles given off by the plant in a one -minute period this is the rate of photosynthesis at that particular concentration of co2. Biology nutrition top factors affecting photosynthesis low light intensity lowers the rate of photosynthesis the concentration of chlorophyll affects the rate of reaction as they absorb the light energy without which the reactions cannot proceed. Salters-nuffield advanced biology resources all users will need to review the risk assessment information and may need to adapt it to local circumstances to investigate how enzyme concentration can affect the initial rate of reaction.
