Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

certain environmental factors affect the enzyme activity rate. For the first experiment‚ where we tested the increase in concentration of enzyme with the substrate‚ we found that higher concentration of enzyme increases the rate of reaction of the enzyme. This is because more enzyme molecules are present‚ which allow more substrate molecules to get into the active sites of the enzyme (Sattler W& Esterbauer H). When calculating the absorbance of different enzyme concentration‚ it was noticeable that

Biomass Essay I think Biomass is beneficial to the Quinault village for the heating project. It will help out are heating sources by building this "wood heated" building . This project will also get rid of all the wood bundles in our woods that would help the environment by not burning the wood piles with like for‚ example pouring gasoline onto the wood bundles or (oil and etc.) and that would be putting more chemicals in the air as if there is enough going on in this earth. this inspires

Overview: Life at the Edge The plasma membrane separates the living cell from its nonliving surroundings. This thin barrier‚ 8 nm thick‚ controls traffic into and out of the cell. Like all biological membranes‚ the plasma membrane is selectively permeable‚ allowing some substances to cross more easily than others. Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins The main macromolecules in membranes are lipids and proteins‚ but carbohydrates are also important. The

This will be the second time I make one of these essays and as a person who has experienced an AP course I am thrilled to express what I have accomplished and the objectives I want to attain for my future in AP. Before entering my first AP Class there was only a feeling of fright and a part of me was ready to bail so I could run back to the normal classes. However‚ now that I look back I am glad that I did not run away. Due to the Pre-AP and AP course that is offered by the school I was capable of

Enzymes are organic catalysts; where a substance speeds up the rate of chemical reactions without changing being changed by the reactions. In lab they tested this by seeing how H2O2 and the catalysts from the banana and liver react to make H2O+O2. Depending on different conditions; like decomposition of H2O2 (surface area)‚ temperature on function‚ reusing the catalase‚ reaction rate of iced liver returned to room temperature‚ and effects of pH on enzyme activity‚ to see how much O2 was released

In the column “The Ethicist” by Randy Cohen‚ he received a question from a reader. It demonstrated how parents are concerned about teachers exchanging donations‚ from students‚ for a grade. They believe that this action defeats the purpose and value of charities and donations. Students can easily set expectations for receiving a reward after achieving a considerate act. However this exchanging process is able to inspire students to take generous actions in their future. The exchange can give a student
