Enzymes

Enzymes are biological molecules (proteins) that allow certain chemical reactions to take place much quicker than reactions would occur on their own. Enzymes function as catalyst, which means they speed up reactions by providing an alternative reaction pathway of lower activation energy (cite). Each step of a pathway typically requires a specific enzyme, without the specific enzyme, the pathway can not be completed. In addition, enzymes do not undergo permanent reactions and remain unchanged by…

industry. Enzymes are. Enzymes are biological protein catalysts that encourage chemical reactions by lowering the activation energy needed for the reaction to take place. Once the reaction is complete, enzymes are left unchanged and able to move on to the next reaction. For this reason, enzymes have proven to be valuable resources for industries. The reusability of enzymes are especially useful in food production, fabric manufacturing, and waste management. Despite the specific conditions…

various temperatures on Enzyme activity Introduction: The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not happen easily. An enzyme is a macromolecule serving as a catalyst, they are generally a protein based molecule, as it is in the lab, Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently changed or without being consumed, which makes enzymes different…

The purpose of this lab is to find the optimal pH of the enzyme peroxidase, which is found in plant and human cells as a byproduct of photorespiration, photosynthesis or cellular respiration. This is significant because an enzyme operating in nonoptimal pH could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation,…

Introduction Enzymes are an important biological catalyst that is absolutely crucial for life to exist. The ultimate purpose of this experiment was to examine enzymes and how they function in cells, explore the result that concentrations and environmental factors have over these functions, and lastly to read and interpret graphs related to enzyme function. This type of study had various parts, therefore there are various hypotheses. The first being, if it is potato extract, then it will contain…

Enzyme catalysis can be a very confusing and long process, but in easier terms can just be explained by the fact that enzymes break down molecules into smaller pieces. The objective of this lab is to observe how quickly the enzyme catalase breaks down H2O2, and what long periods of contact between the two do to that process. We used seven different cups for seven different lengths of time, and in every cup we mixed 10 mL of 1.5% H2O2, 1 mL of distilled water, and 1 mL of catalase. We then…

Most proteins are enzymes, which have an essential role in biological catalysis by increasing the rate of a reaction. The experiment conducted included an enzyme assay with the enzyme catalase and the substrate hydrogen peroxide. To complete the assay, the catalase enzyme was added to the hydrogen peroxide buffered solution. Every thirty seconds, portions from the tube was removed and placed into the labeled tubes. Based on the degree in color of each sample, a different absorption value would…

Introduction Enzymes, which speed up a chemical reaction without being consumed or changing the products of the reaction, are very important because they control the cellular activity of all living organisms. Enzymes are also described as being “catalysts”. In biological systems, specific enzymes catalyze particular cellular reactions. Each enzyme has a unique 3-D shape, and this shape determines which reaction it catalyzes. However, in order for a chemical reaction to move forward, an energy…

most optimal for enzyme functionality and how they affect enzyme functionality. Enzymes help speed up chemical reactions in the body and lower the activation energy to do so. Enzymes can also aid with metabolism and digestion. They can break down larger molecules to smaller molecules that are more easily absorbed by the body. A substrate is the reactant that is acted upon by an enzyme in a chemical reaction. The substrate attaches itself to the active site, the place where the enzyme catalyzes. …

When a blank containing boiled (denatured) enzyme instead of an active enzyme could be used but it would not be the better blank to use in this experiment. The better blank solution would have been the one with active enzyme because it would cause the spectrophotometer to measure the absorbance of every component in the blank except the substrate, creating a 100% transmittance. This allow the spectrophotometer to read everything that was not in the blank when the actual sample is inserted in…
