Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Slowing the Biological Clock Team B BSHS 371 July 23‚ 2012 Rafael Gomez Slowing the Biological Clock The biological clock is an organism’s rhythm that controls the cycle of behaviors that occur on a daily basis. Slowing the biological clock is in reference to the cells that are constantly changing in an individual’s body. A person should take care of his or her body at a young age because the effects of the care will have outcomes as the person ages. There are several contributing

Major Biological molecules There are many Biological molecules but this discussion will be about the 4 Major biological molecules and how they are used in a living system. This discussion will also include major subtypes of molecules. The four Major biological molecules are Carbohydrates‚ Lipids‚ Proteins‚ nucleic acids. Carb is an abbreviation for carbohydrates. The body breaks down carbohydrates into simple sugars. Carbohydrates are easily used for energy by the body. The nervous system and brain

Introduction There are many ways cells dispose of toxic molecules in order to maintain the necessary internal environmental conditions to survive. These toxic molecules are known as free radicals that contain an unpaired electron on the outer orbit (Proljsak et al.2013). Some examples of free radicals that can be found in the cell are superoxide (O2-)‚ hydrogen peroxide (H2O2) and even reactive metals like copper and iron. These free radicals are produced based on the environment the individuals

1. There are three principles that define the biological level of analysis: there are biological origins of behavior‚ animal research may provide insight into human behavior‚ and to an extent human behavior is genetically based. The first principle (biological origins of behavior) deals with the idea that neurotransmitters‚ hormones‚ and other specific brain processes can have an effect on behavior. For example‚ one study looked at criminals charged with murder who testified “Not Guilty By Reason

Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the

1. Biological psychologists are gaining a better understanding of our experiences of sights and sounds‚ meanings and memories‚ pain and passion. Franz Gall invented phrenology‚ a popular theory that claimed that bumps on the skull reveal our mental abilities and our character traits. Although wrong‚ this information revealed that various brain regions have specific functions. 2. A neuron consists of a cell body and branching fibers:The dendrite fibers receive information from sensory

This experiment was performed in order to analyze the effects of pH‚ enzyme concentration‚ and temperature on the catalytic rate on enzyme ALP. The initial experiment was done to approximate the optimum pH for the activity of the enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state
