Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

Detection of changes in blood pressure (leading to resultant changes in blood vessel diameter): Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. Afferents from the carotid region form the

tire condition that can occur is low tire pressure/ under inflation. According to the Webster’s dictionary‚ under inflation is the insufficient presence of air pressure in a tire for the amount of load carried and vice versa for over inflation. This paper will examine the causes of reduced tire pressure‚ the tire pressure in places abroad‚ effects of under and over inflated tires‚ and tire pressure as it relates to furl consumption. To begin with‚ tire pressure is a measure of the amount of air in a

What factors have led to increasing incarceration rates? How has this affected the United States economically and socially? Life‚ as we know it today‚ isn’t the way it was before because of the increase in incarceration rates within our nation; especially among our minority groups. When minority groups are mentioned‚ it’s aimed towards people that are different from the social majority. Incarceration is the state of being confined in prison; imprisoned. There are various factors that have led to

EFFECTS OF PEER PRESSURE ON DECISION MAKING Amanda M Romero Learning Across the Lifespan Abstract Our Peer-to-Peer interaction affects us every day. From decisions‚ we make‚ to the places we go. It is human nature to listen and learn from other people. Though we would like to think we have control over outside influences‚ studies show that our surroundings play a key role in how we function. Solomon Asch’s (1950) social experiment demonstrated‚ consumers often modify their responses‚ consciously

Symptoms of dengue shock syndrome-the most severe form of dengue disease-include all of the symptoms of classic dengue and dengue hemorrhagic fever‚ plus • Fluids leaking outside of blood vessels • Massive bleeding • Shock (very low blood pressure) This form of the disease usually occurs in children (sometimes adults) experiencing their second dengue infection. It is sometimes fatal‚ especially in children and young adults. ASSESMENT 11 Year old male pedia patient with Dengue Hemorrhagic

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic
