(100 ºC) and an acidic pH. Enzyme C produced the most maltose at 37 ºC (body temperature) and a pH of 7 (neutral). Conclusion In a prior lab‚ it was given that the enzyme Aspergillus oryzae (fungus) works best at warm temperatures and an acidic pH‚ porcine (pig) works best at body temperature (37 ºC) and

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Table 8.1- Combustion of magnesium ribbon Observations Reaction was exothermic; magnesium ribbon burned and was glowing a bright white color when ignited. Reactants: Mg and O2 Products: MgO Balanced chemical equation 2Mg + O2 2MgO Table 8.2- Combustion of heptane Observations When holding test tube inverted over heptane flame‚ condensation formed against top walls of the test tube. When the burning splint was added the walls of the test tube became less foggy from the condensation

Unlike most coefficients in Physics‚ friction behaves differently depending on whether the object is at rest or at motion.

The purpose of the study was to design a suitable Transdermal therapeutic system for Venlafaxine Hcl (VFH) with the objective to prolong the release to be used for controlled release drug delivery.Transdermal patches of VFH with a HPMC-drug reservoir were prepared by the solvent evaporation technique. In this investigation‚ theEudragit RSPO membrane in different concentrations was cast to achieve controlled release of the drug. The absence of physiochemical interactions between VFH and the polymers

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention
