increasingly complex models at all levels of biology. This paper shows the innovations in studying biology. It discusses the biological level of organization and it also describes the model that has seem to be found on the said level. It was also discussed on this paper that the complex models that was developed for the past few years must have the new methods and techniques to model it. The journal tackles the level of organization‚ multi-scale in modelling in biology‚ MD of ion channels and heart modelling

Lab report nº4 The aim of this experiment was to observe the change of enzyme reaction with different concentration of solution. For this experiment we used potato enzymes (catalase) and hydrogen peroxide in concentrations of 100%‚ 80%‚ 60%‚ 40%‚ and 20% According to P.George: “When catalase is added to hydrogen peroxide‚ there is an initial rapid evolution of oxygen which lasts for about two minutes‚ depending on the peroxide concentration. After this‚ oxygen is given off at a steady rate which

Abstract Enzymes are proteins that lower the activation energy needed for chemical reactions. The two main environmental factors that can affect the enzyme’s activity are temperature and pH‚ and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic experiment was to observe the effect of temperature and pH on the reaction of barley alpha-amylase enzyme with starch substrate and establish the optimum temperature and pH for this reaction. The optimum temperature

Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration
