The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

between the amount of substrate in the assay solution and the rate of the reaction when the enzyme and buffer in the assay are held constant were experimented. We analyzed the change in absorbencies over time for varying substrate concentrations. There were four experimental assays which contained 1% enzyme solution‚ substrate solution of 0%‚ 1%‚ 2%‚ and 3% concentrations‚ guaiacol‚ and pH 7 buffer. At 2% concentration there was a greater enzymatic activity and at 3% concentration enzymatic activity

The working memory model consists of four main parts‚ phonological loop‚ visual spatial sketch pad‚ episodic buffer and the central executive. The central executive controls the three subsystems in addition to this the WMM represents Short Term memory (STM) and shows us multiple ways of information being transferred into the Long Term Memory (LTM). The Phonological Loop of the WMM is called the inner voice‚ this holds verbal information in a speech based form‚ and this however has a limited capacity

Abstract The catalysis of enzymes within our bodies is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze

Historically‚ separation methods were limited and as a result precipitation methods were highly used with very fine cuts in ppt conditions. As more choices of inexpensive and quality resins are commercially available precipitation
