Enzymes Lab Report

Enzymes are biological catalysts that speed up chemical reactions, without being used up or changed. Catalase is a globular protein molecule that is found in all living cells. A globular protein is a protein with its molecules curled up into a 'ball' shape. All enzymes have an active site. This is where another molecule(s) can bind with the enzyme. This molecule is known as the substrate. When the substrate binds with the enzyme, a product is produced. Enzymes are specific to their substrate, because the shape of their active site will only fit the shape of their substrate. It is said that the substrate is complimentary to their substrate.

Enzymes are very specific protein because they contain one active site on their surface that

Enzymes are able to catalyse due to their globular structure which has a region on their surface that has a specific shape. This shape is complementary to the shape of the reactant or reactants of the reaction that the enzyme will catalyse. This region on the enzyme is referred to as the active site which binds to the substrate in order for the reaction to occur.

Enzyme Lab Conclusion In this lab three hypotheses were tested. If the catalase Solution is added then, the H2O2 will be broken down into harmless byproducts/ there will be an increase in temp compared to the control, if the boiled catalase is added to the H2O2, then there will be no significant increase in temp compared to the control, and if the catalase with acid is added to the H2O2, then there will also be no significant temperature increase compared to the control. The first hypothesis of, if the catalase solution is added to the H2O2, then there will be an increase in temp compared to the control, was proven correct. The control(the H2O2 with no catalase added) stayed at a constant temp of 23.5 degrees celsius throughout the 5 minutes

For the experiment, the enzyme Catalase was used at varied temperatures to measure oxygen produced by the breakdown of H2O2. Most enzymes are specialized molecules of protein that have a specific structure to them. They are catalysts in metabolic activity. Being that they are made from proteins, the shape comes from the folding or condensing of the long strands of amino acids. These polypeptides fold from primary, to a secondary, then tertiary structure.

This is because glass looks that same when hot as it does at normal temperature, so use tongs to avoid burns. Also, allow the test tube to cool down before being put into the ice bath, and to heat up before being placed in the boiling water. This is because glass will break when subjected to major temperature changes so allow adequate time in between hot and cold water stations. Goggles should also always be worn when preforming labs to avoid any substance getting in

Enzymes have a certain shape which when the right chemical molecule for that enzymes shape comes along, it will match the shape perfectly. The area of the certain shape is referred to as the active site of an enzyme, and the molecule that the enzyme works on is known as the substrate. The shape of an enzyme only matches with one type of molecule (Abpischools.org.uk, 2016). Different factors can affect the rate at which enzymes work, the main two factors are pH and temperature. By increasing the temperature, the kinetic energy of the enzyme and the substrate molecules increases as well, this means that they move around faster and have a higher chance of colliding with a molecule.

To catalyze a reaction, an enzyme will bind to one or more reactant molecules. These molecules are the enzyme 's substrates. The part of the enzyme where the substrate binds is called the active site. In enzymes that are proteins, the active site gets its properties from the amino acids it 's built out of. These amino acids may have side chains that are acidic or basic. The set of amino acids

One reason why observational studies and randomized trials yielded different results was observational studies cannot determine whether one event was the cause of another event. Observational studies are only capable of gathering information that may serve as evidence in preparing a hypothesis. They are not able to predict that one event is directly responsible for another event. In this article, researchers gathered information that since

Consequently and in general, there is a noticeable difference between the analyses accorded to the fresh evidence

The inconsistency of results may be due to the heterogeneity between the participants sampled (Henry & Rendell, 2007). Participants involved in previous studies

Additionally, one of the participants (Alan) had exercised earlier in the day, possibly reducing muscle efficiency. This represents a systematic error since all of the trials done with Alan might have lower efficiency than expected. There was also one trial (70 bpm for participant 2, Matt) where the nose plug fell off in the

Each enzyme has specificity that is a result of the shape and types of R-groups involved at the active site (Freeman, 2014, p. 54).

If the substrate does not fit, the enzyme would not be able to react on the substance any longer. An enzyme’s active site is the area of an enzyme where the substrate fits into an enzyme to form a chemical bond. The active site, just like the rest of the enzyme, can change size or shape depending on the temperature and the pH in its environment.

With any study, there are limitations that are not counted for in the study, which may result unfavorably. Because we found no significance in all but one hypotheses, many factors may be contributed.
