Conclusion

From the results I had gathered after doing this experiment I found
that when I increase the concentration of the Catalase Enzyme (by
adding more liquidised potato parts to water parts) the rate of the
reaction is greater and this affects the enzyme activity.

Concentration and How It Affects The Rate of Reaction

When two reactants are in the same fluid phase, their particles collide more frequently than when one or both reactants are solids (or when they are in different fluids that do not mix). If the reactants are uniformly dispersed in a single homogeneous solution, then the number of collisions per unit time depends on concentration and temperature, as we have just seen. If the reaction is heterogeneous, however, the reactants are in two different phases, and collisions between the reactants can occur only at interfaces between phases. The number of collisions between reactants per unit time is substantially reduced relative to the homogeneous case, and, hence, so is the reaction rate. The reaction rate of a heterogeneous reaction depends on the surface area of the more condensed phase.

concentration clearly affects the rate of reaction.

However, more yeast are damaged in dough frozen at a fast freezing rate, resulting in greater cell death; therefore, more glutathione is released, which affects the gluten network by reducing S-S to sulfhydryl groups (-SH) and decreasing the amount of gas retention. shows the effect of the trehalose concentration and storage time on CO2 production.

The procedures to administer intravenous drug delivery have been evolved from simple manual delivery and computer-assisted automated Target Controlled Infusion (TCI) to more sophisticated Closed-Loop ANesthesia (CLAN). Traditionally, hypnotic drug delivery rates in intravenous anesthesia are manually controlled by an anesthetist. Doses are principally decided based on patient demographics, qualitatively measured signs (e.g. presence of certain reflexes, movement) and quantitatively measured signals (e.g. oxygen saturation, blood pressure, heart rate). The dosage scheme is then tuned by hit and trial to optimize anesthesia and to evade toxicity. TCI, also known as Computer Assisted Continuous Infusion (CACI), relies on population-based pharmacokinetic (PK) and pharmacodynamic (PD) models for calculating an adequate infusion profile to achieve the reference drug concentration set by the anesthesiologist. Given the past and present infusion rates, these models can predict the time evolution of plasma concentration. This prediction is then used to track the reference concentration thus devising an open loop control paradigm. Instead of adjusting the infusion rate, the anesthetist manipulates the reference concentration, both reactively and proactively, using commercially available infusion pumps. TCI systems suffer from drawbacks of sensitivity to model non-linearities and disturbances since there is no feedback of measurement on drug effect. These drawbacks can be addressed by closing the control loop through DOH measurement, which is given by EEG-based monitors e.g. Bispectral Index (BIS). The value of BIS is mapped to the DOH level of a patient based on the scaling band shown in . The value of 100-90 corresponds to a fully awake state while level of 90-60 and 60-40 indicate light and moderate hypnosis levels respectively. The moderate level represents the surgical procedure band in which general surgery is performed by clinical professionals. Level beyond deep hypnotic state (40-20) is quite dangerous.
