Estimating Osmolarity by Change in Weight Abstract Optimum water content for normal physiological processes in plants is crucial. In order for normal activities to take place‚ the amount of water relative to osmotically active substance (OAS) in cells must be maintained within a reasonable range. The one way to estimate optimum water content is to find osmolarity of plants cells. Osmolarity can be indirectly measure by comparing change in weight and volume when plant cells are incubated in

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

changes in enzyme function? Objective The objective of this experiment is to observe if changes in temperature will cause a disruption in enzyme function. Hypothesis If we add and boil enzyme in L-Dopa‚ then the color will become darker because the temperature will denature some of the enzymes.

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis
