Download file to see previous pages A cell on the other side is the smallest fundamental unit of life (Alberts 79). Within the cell are the cell organelles that are charged with specific roles in driving physiological processes of the body.
Most of the physiological processes that take place in the body are initiated at the cellular level, at the same time; the cell operation is linked with the enzymes activity. An example is the process of gene expression in the body. Gene expression is the sequential transformation of a trait from the molecular level to phonotypical stage. It usually starts with the replication of the DNA (deoxyribonucleic Acid) (Hill 84). The replication of the DNA is enzyme catalyzed and the process continues to the transcription of the DNA to RNA (Ribonucleic Acid) which then gives the amino acid and is finally translated to proteins that manifests themselves phenotypically (Alberts 102). In the sequence of gene expression, the cell is charged with the responsi679114bility of determining what enzymes are to be produced and in what quantity.
It is the responsibility of the cell to determine what enzyme is required in the body depending on the type of substrate that is present in the body. The situation shows how intimate the two work in enabling the body physiological processes to proceed without a halt. The alternative synthesis and degradation of the enzymes is referred to as the turnover number, this turnover number is dependant on the need of the enzymes in the cell and is regulated by the cell (Hill 166). Increasing the amount of the enzymes in the cell can be done by the cell in two way; elevating the synthesis rate of the enzymes or by slowing the rate of the enzyme degradation. The cell in this case has the role to regulate the enzyme content in it which is a stringent exercise owing to the fact that there are millions of enzymes in the body each effecting a unique role probably at the same time and has to be ...Download file to see next pagesRead More

Russia's Most Important Economic Sectors
...?Russia's Most Important Economic Sectors Introduction: Russia is the ninth biggest economy in the globe according to the nominal value. It is blessed with natural resources like coal, gas, oil, timber, and some precious metals. The well organized utilization of these resources had been a challenge for them after the collapse of Soviet Union. Russia has undergone many significant changes after collapse. In 2009, Russia was the leading exporter of natural gas, the second largest exporter of oil and the third leading country in exporting of steel and primary aluminum. The global commodity prices showed a high volatility on that time and that made the government think about the development other sectors;...

Privacy is not the most important right
...Privacy Is Not the Most Important Right Privacy is not the most important right Privacy does not entirely form the most fundamental right acknowledged in a good number of regional and international treaties such as International Covenant on Civil and Political Rights and the United Nations Declaration of Human Rights. Privacy underscores the basic human dignity and other essential human values such as freedom of speech and freedom of association (Rolv, 2003). In a progressive society, privacy is rarely an issue of concern. However, privacy does not really constitute the most fundamental right in human...

Privacy is not the most important right
...have marked differences in the idea to the extent to which a person is authorized to keep his personal data and information private and what is the boundary limits for another person or body to interfere into the private life and data of the other person or body or organization. Some nations and religions believe that privacy is a fundamental right of the people and they must be free to practice privacy to any extent. It is also considered that it is the right of a person that no one other than the person concerned can interfere in the private data; in fact it is against the law and a serious crime to break into the private data of a person without his acknowledgement and permission (Starkey, 2012). But privacy is not...

The most developed countries have been targeted through computer attacks where fraud committed through these systems has increased in the modern world. This requires a robust governmental strategy to defend its citizens against illegal exploitation through computer related crimes. If these computers are attacked mostly through viruses, other services are affected. This is because while computers are used for most office work in the modern world, they also control other...

Soil Enzyme Activity
... Soil Enzyme Activity Abstract Soil microorganisms have the ability to breakdown insoluble nutrients in the soil to produce extracellular enzymes. These are protein compounds produced inside microbial cells but exported externally to catalyze reactions that breakdown nutrients source to make it available. Alkaline Phosphatase is an example of such enzymes and function to cleave the phosphate molecule from the organic compounds such as nucleic acids and phospholipids. This paper aimed at measuring the amount of active enzyme in the soil samples by applying chromogenic substrate assay. Using soil samples with organic fertilizer, inorganic fertilizer, combined and unammended, alkaline phasphatase activity was tested under control... in the...

Enzyme Activity
...Enzyme Activity Introduction Enzymes are biological catalysts that are used in hastening biochemical reactions. Without the presence of enzymes, most chemical reactions in the body such as respiration would take a very long time to come to proceed. In addition, a lot of heat would be generated and lead to the destruction of living cells. Enzymes increase the rates of these reactions by lowering the activation energy of the reactions. Activation energy can be described as the least amount of energy that is needed for reacting substances to go through a reaction. An enzymatic reaction...

Lactase Enzyme Activity
...Lactase Enzyme Activity Introduction Enzymes are biological molecules made up of a complex protein that catalyze specific chemical change in living organisms. In this regard, enzymes are capable of regulating the rate at which chemical reactions occur without being altered in the process. Enzymes achieve this function by lowering the activation energy necessary for reaction to occur in cells. The minimum energy that is required for a chemical reaction to occur and yield products is called the activation energy. Even though reaction can still occur within the cells and...
