Importance of plants from an economic, nutritional, environmental and medicinal point of view
Inga [223]

Answer:

Plants are extremely important in the lives of people throughout the world. People depend upon plants to satisfy such basic human needs as food, clothing, shelter, and health care. These needs are growing rapidly because of a growing world population, increasing incomes, and urbanization .

Plants provide food directly, of course, and also feed livestock that is then consumed itself. In addition, plants provide the raw materials for many types of pharmaceuticals, as well as tobacco, coffee, alcohol, and other drugs. The fiber industry depends heavily on the products of cotton, and the lumber products industry relies on wood from a wide variety of trees (wood fuel is used primarily in rural areas). Approximately 2.5 billion people in the world still rely on subsistence farming to satisfy their basic needs, while the rest are tied into increasingly complex production and distribution systems to provide food, fiber, fuel, and other plant-derived commodities .

Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the ‘whole population’ and ‘high-risk’ strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted.

A typical human cell expresses only about 5% of its genes at any time. The expression of a gene can be regulated during any step
ANTONII [103]

Answer:

Enzymes

Explanation:

The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.

During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.

The first stage of cellular respiration glycolysis is an anaerobic process. During glycolysis glucose is converted to two molecu
Oduvanchick [21]

Answer:

Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.  

Explanation:

To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
