speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has a fixed shape in which a certain the substrate will fit into. The sequence of the amino acids in the enzyme determines

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

the essential components of the research study. There will be a decrease in temperature in the newborn if having difficulties breastfeeding while having skin-to-skin contact with the mother. That was the inferred hypothesis. The method used to gather the information was a pretest-test-posttest study design and the sample consisted of 48 full-term infants. The key findings showed most infants reached and maintained temperatures between 36.5 and 37.6 degrees Celsius‚ the thermo neutral range‚ with only

know that 250‚000 life organisms die a year because of the ocean temperatures rising? One reason the ocean temperature surges is because of the greenhouse gas. As greenhouse gas (a gas from the greenhouse effect that benefits by absorbing carbon dioxide‚ chlorofluorocarbons‚ and infrared radiation; different kinds of elements and gases) collects together and increases‚ it traps more heat energy into the Earth‚ and making the temperature rise. Another way this is caused is when the warmer ocean water

MIP experiment on the melting temperature of different polymers 8.1 Compare and comment on the results obtained. LDPE has the lowest average melting temperature (103.6°C) out of the 4 polymers. It is because LDPE is a linear polymer that has a branched structure which is able to expel the applied heat faster through the “branches” and melt faster. HPDE has the second lowest average melting temperature (139.5°C) out of the 4 polymers. Unlike LDPE‚ HDPE does not have a branched structure and the

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Temperature affects enzymes in two different ways: by increasing the kinetic motion of molecules‚ changing the rate of collisions between them and the hydrogen bonds it’s 3D structure(D. Fraser‚ 55). There is a specific temperature for every enzyme where activity is maximized‚ and also where an enzyme becomes denatured. An enzyme becomes denatured when it is heated at extreme temperature; the excessive kinetic movement of the amino acid begins

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the
