Download file to see previous pages Role of enzyme: enzymes catalyze physiologic reactions by decreasing the activation energy level that the reactants (substrates) must reach for the reaction to occur. They cannot alter the equilibrium of a reaction but can only decrease the activation energy of the reaction thereby accelerating the reaction rate.
Activation energy: it is the amount of energy that is required to raise all molecules in one mole of a compound (substrate) at a specified temperature to the transition state at the peak of the energy barrier.
Free energy of activation: it is the energy barrier that prevents chemical reactions. Reactants processing enough energy to overcome the energy barrier participate in product formation .The enzyme activity is determined by the rate of an enzyme catalyzed reaction under certain defined conditions2.
Reaction rate/velocity (v): it is the rate of conversion of a substrate to products per min (mol/min). The reaction rate is proportional to the concentration of reacting molecules.

A + B C + D
If concentration of A and B is doubled, the rate of reaction is also doubled.
At equilibrium, forward reaction and backward reaction are equal, so that
A + B C +D
Forward reaction R1 = K1 [A] [B]
Backward reaction R2 = K2 [C] [D]
At equilibrium R1 = R2 OR K1 [A] [B] = K2 [C] [D]
OR K1/K2 = [C] [D] / [A] [B] = Keq or Equilibrium constant...

Numerous aspects are known to subsist, which further create an impact on the consumer purchasing behaviour such as social class, family and reference groups (Bearden & Etzel, 2001). The recent researches, based on a similar notion, have often argued that social grouping influences consumer behaviour quite strongly and inevitably...

Factors Influencing Exchange Rate Between the US Dollar and Euro

...? Factors Influencing Exchange Rate between the U.S. Dollar and Euro Factors Influencing Exchange Rate between the U.S. Dollar and Euro A look into the performance of dollar shows that it fell by 30% against euro in the year 2010. As Rahn (2003) points out, in the place of the 80 cents one had to pay for each euro in 2009, presently, one has to pay 1.24 dollars per euro. While some scholars argue that a further fall is in the pipeline, a rational assumption is that as dollar already reached its minimum, its value is likely to improve in the coming years. The various factors that are considered as influencing factors on dollar-euro exchange rate are the international real interest rate differential, relative prices in the traded and non...

Virulence Factors of Candida Albicans

 The virulence factors are all the factors that are related in the process of morphogenesis, adhesion, penetration, and colonization of Candida in tissues and blood vessels. Since the hyphal form is often associated with infection, the understanding of hypha-specific cell surface components may help in the identification of the proteins responsible for morphogenesis and virulence. Fungal infection can be treated by the prevention of hyphal development in C. Albicans by antifungal drugs. Understanding Candida biology, genetics, and molecular mechanisms may lead to novel effective antifungal therapy for drug-resistant organisms.

With the help of this strategy, it can survive and grow on the skin, mucosal surfaces and...

Physiological Factors While Dealing With Health Issues

The body’s metabolism includes all the physiological processes in the body. Enzymes serve as catalysts to biochemical reactions that form a part of metabolism. The two distinct chemical phases of metabolism are anabolism and catabolism. Anabolism consists of building up carbohydrates, proteins, fats and nucleic acids from simple molecules, through the use of energy. Anabolism is responsible for processes such as growth, repair, and reproduction. On the other hand, catabolism is the process by which large complex molecules are broken down into smaller, simple molecules, with the release of energy. Metabolic processes are carried out by the cell organelles, each organelle has a distinct and crucial function. Every animal cell...

Factors Determining Voting Patterns in Youth Vote

It is estimated that 3.4 million more young people cast their ballots in this election than in the election of 2004, and the surge in youth turnout accounts for at least 60 percent of the total increase in voter participation in 2008. Voters under the age of 30 increased their share of the overall electorate to 18 percent, up to one percentage point from the previous 1996 to 2004 elections, according to the National Exit Polls (NEP) conducted by Edison and Mitofsky. (Pawlenty, 2008, p. 2) The impact of the youth vote proved crucial in claiming the battleground states of Florida, Ohio, and Virginia. Thanks to the youth vote, these electoral college vote-rich states were successfully converted to blue (Democratic) states (Bell, 2008...

What Are the Most Important Factors in Explaining the Rise of the Modern State

Though the existence of the state can be felt in different walks of everyday life, yet it is an intangible whose nature is impossible to grasp. As a political institution, state embodies the concept of sovereignty. Devetak (2007) describes it as a political unit or a country that possesses sovereignty. State can thus be described as a single, unified whole confined within territorial borders. The state is built in a core geographical area with allowances to a certain extent on the boundaries. According to Strayer (1970), a state exists in the hearts and minds of the people. The collective personality of the state renders it immortal. The state is a multi-faced concept that is fuzzy around its edges. Consequently, we cannot develop...
