Potato enzyme lab essay sample an enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism a good rule of thumb is to remember that enzyme names end in -ase.

Enzyme activity lab hypothesis: 1] are enzymes reusable yes, enzymes are reusable 2] which of the following do you think contain catalase [manganese dioxide, chicken meat, apple, carrot, potato, or chicken liver] i think that the manganese dioxide, apple, and carrot contain the catalase. Analysis instead of filtering out poor data for my results i have decided to select the best result to concentrate on i removed quite a few results. Prepare enzyme catalase by inserting through the centre of the potato, with aid of a cork borer using the scalpel and ruler, cut 1cm pellets of potato that was extracted with the cork borer half-fill a beaker with tap water and add in crushed ice to make water bath for a wait for several minutes to allow stabilization of temperature. In decision, enzyme catalase exhibits low activity at low temperatures ( 05oc ) and high temperatures ( 612oc ) its activity is the greatest at around 35oc the experimental set-up was by and large satisfactory to minimise mistakes except of some defects such as the methodological analysis in mensurating the rate of the reaction. In this pre-designed procedure the enzyme activity of catalase in a potato was tested, in the form of measuring the volume of the oxygen (o2) released by a catalase - hydrogen peroxide (h2o2) reaction in the span of one minute.

 investigation into how ph levels affect catalase activity in potato samples - (enzymes) introduction: the aim of this investigation is to understand and monitor the effects ph levels have on catalase activity within controlled potato samples. The effect of substrate concentration on the activity of the enzyme catalase a level biology project aims this is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Answer: i am a first-year ap teacher and i did the enzyme lab with my kids using one large potato, diluted h2o2, and lab filter paper i found in my room we peeled and cubed the potato, put it into a blender with chilled distilled h2o almost to the top, and pureed it. The enzyme catalase can be found mostly in liver cells and in potato and many other plant foods aim: to investigate the oxygen collected in hydrogen peroxide using different sources of plant food samples.

The enzyme potato catalase essay

The potato contains less of the enzyme catalase, therefore requires more activation energy, slowing down the rate of reaction show the fully labeled balanced chemical equation for the decomposition of hydrogen peroxide. The activity of potato catalase essay a ph for the enzyme catalase to function in is a ph of 6 3 as it the enzyme is forming a complex with the substrate and. Catalase is a naturally occurring enzyme that is found in many living organisms such as plants and the human body catalase breaks down hydrogen peroxide, a very harmful oxidizing agent for cells (catalase. Influence of temperature on the activity of potato catalase - influence of temperature on the activity of potato catalase hypothesis that the higher the temperature the higher the reaction rate of potato catalyse to a point were denaturing occurs in the enzyme and the reaction rate of the potato catalase drops off.

The enzyme which is going to be used in this practical is catalase catalse is a very common enzyme which is found in almost all living and root vegetables such as, celeriac and potatoes catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. The effect of temperature on the enzyme catalase stephen francis biology 183 abstract this experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. Catalase is an enzyme found in human organs such as the liver and kidneys, and is associated with the organs' roles of cleansing the body of toxins absorbed from ingested food catalase is also found in plants potatoes, particularly, contain high amounts of catalase, which is mysterious because.

) 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.
