Experiment ep-2: the effect of exercise on metabolism and body temperature assistants and their duties 1 at least two other students, who are not subjects, should join each pair of subjects to form a lab group while one of the subjects is performing the exercises, the other subject and the other.
Part b: investigating the effect of temperature on enzyme activity copy the lab title and fundamental question into your lab notebook use your observation and knowledge to develop a testable question about how temperature will affect the rate at which bromelain breaks down the gelatin. Aims the aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. Before starting my investigation on how temperature affects the rate of photosynthesis i carried out some research into photosynthesis from this initial research i made a prediction based on the evidence that i found about the enzyme rubisco that is used in the dark stages of photosynthesis, and also on the limiting factors of light intensity, carbon dioxide concentration and temperature. An investigation into the effects of temperature on enzyme action an investigation into the effects of temperature on enzyme action an enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions.
Investigate the effect of temperature on amylase activity introduction amylase is an enzyme that catalyses the breakdown of starch into sugars amylases are found in almost all plants, animals and microorganisms. (the temperature coefficient of resistance of many pure metals is close to 0004 k-1, so the resistance/temperature graph will extrapolate back to 1/0004 = 250 k) you could link this to the idea that the resistance of a pure metal at room temperature is dominated by the vibration of ions, and this will reduce to zero close to 0 k. Gradient plates were used to investigate the effects of varying temperature, ph, and sodium chloride (nacl) concentration on nisin inhibition of staphylococcus aureus and listeria monocytogenes, nisin was incorporated into the plates of 0, 50, 100, 250, and 500 iu ml -1.
