Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

LAB EXERCISE: Diffusion and Osmosis Laboratory Objectives After completing this lab topic‚ you should be able to: 1. Describe the mechanism of diffusion at the molecular level. 2. List several factors that influence the rate of diffusion. 3. Explain why diffusion is important to cells. 4. Describe a selectively permeable membrane‚ and explain its role in osmosis. 5. Define hypotonic‚ hypertonic‚ and isotonic in terms of relative concentrations of osmotically active substances. 6. Discuss

There are many factors that can negatively impact the developing person. During prenatal development‚ environmental factors can significantly affect the development of the child. Most everything the mother ingests‚ including food‚ liquid‚ and even medication‚ travels through the placenta to the fetus; anything the mother is exposed to in the environment affects the fetus. The factors that associated with this scenario are smoking‚ alcohol‚ stress‚ nutrition‚ prenatal vitamins‚ and no establish care

What Factors Affect AM And FM Radio Reception? Background Information Communications are carried by waves. One type of communication is AM and FM radio. AM and FM radio’s use radio waves. A radio wave is an electromagnetic wave propagated by an antenna at various frequencies. In AM (amplitude modulated) radio waves‚ the audio signal changes the amplitude of the carrier wave. In FM (frequency modulated) radio waves‚ the audio signal changes the frequency of the carrier wave. Australia’s broadcast

higher concentration ( hypertonic ) to a region of lower concentration ( hypotonic solution ) through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion called “ passive transport “ which means no energy is required. Diffusion is the movement of a substance by which the molecules move from a region of higher concentration to a region of lower concentration. Aim Our aim of the experiment was to observe and investigate the process

Macro and micro environments both fall into the categories of environmental scanning. The general scope of environmental scanning is that it is a component of global environmental analysis. While analyses are typically carried out on the macro environment‚ the micro environment still has an important role to play. In summary‚ the macro environment is involved with the industries‚ companies‚ markets‚ clients and competitors‚ while the micro environment can be represented by the suppliers‚ competitors

And the real impact is that all of them affect organizational performance as well because

2.1 Explain how development of children and young people is influenced by their range of personal factors. There are two main factors which affect a child and young person’s development. The first is personal factors this can be linked to genetics‚ health and learning difficulties all of which influence the development of a child. Then there is personality which is linked to the environment which is influenced later on in the development. Genetics Genetic information about a child is important

Starch Diffusion in a Caterpillar’s Digestive Tract The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane
