Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

FUNCTIONS OF ENZYMES Enzymes are extremely important to the human body and its ability to function. An enzyme itself is a protein made by the body’s cells to act as catalyst‚ speeding up chemical reactions in the cell. It does this by taking the reactants‚ or the elements or compounds that enter into the chemical reaction‚ in this situation referred to as substrates‚ and breaking apart their bonds so that new ones can form. The three types of enzymes are digestive enzymes‚ food enzymes‚ and metabolic

Twin Reaction Write Up Humans are complex‚ yet simple. Dr.Nancy Segal’s discussion was interesting. I enjoyed the fact that she began her lecture with a basis. The basis begin- if we are to look at the study of how twins are similar/different when raised apart‚ then we need to know what sort of twins we are looking at; either monozygotic(identical) or dizygotic(fraternal). I would have had a better understanding if hypotheses were specified‚ but regardless of whether it was‚ I still was intrigued

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic

the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials

reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it‚ when you write‚ ink comes out‚ right? You can draw‚ you can write‚ then when you finish and get your pen off of the paper‚ the ink stops coming out. Enzymes are like that‚ they

Information System MGCR 331-005 Guest Speaker Talk Write-up IT is all about cutting people/time Jean Thibodeau defines IT as a mean to max efficiency. I totally agree on that. With IT‚ the way people deal with data is much more efficient. Data storage‚ transmission‚ manipulation can all get done with a click of mouse.

Short Write-up –Innovation across Firm Boundaries Xin Gu 1. What were some key problems in the Alpha-Omega alliance? What caused them? First‚ both firms were accustomed to getting their way" with alliance partners because of their market clout and size; but this situation was different. Since both companies rarely compromised‚ partnership discussions were arduous. At one low point‚ both sides refused to give in on a particular issue‚ and one team coldly got up and left. Second‚ one major hurdle

Factors Affecting Enzymes The activity of an Enzyme is affected by its environmental conditions. Changing these alter the rate of reaction caused by the enzyme. In nature‚ organisms adjust the conditions of their enzymes to produce an Optimum rate of reaction‚ where necessary‚ or they may have enzymes which adapted to function well in extreme conditions where they live.Increasing temperature increases the Kinetic Energy. In a fluid‚ this means that there are more random collisions between molecules
