Biochemical reactions in living organisms are essentially energy transfers. Often they occur together, "linked", in what are referred to as oxidation/reduction reactions. Reduction is the gain of an electron.
Biochemical processes are heat dependent. The rule of thumb is that they go faster when they are warm and slower when they are cold.
biochemical taxonomy A biochemical approach to defining evolutionary relationships of organisms by determining molecular similarities and differences among organisms.
The biochemical material, either RNA or protein, resulting from expression of a gene. The amount of gene product is used to measure how active a gene is; abnormal amounts can be correlated with disease-causing alleles.

Gene: A biochemical unit of hereditary, often coding for an entire protein.
Generalist: A pest or natural enemy that can utilize a wide range of species as host or prey.
How Are Biochemical Solutions Sterilized?
In the mid-1800's, the process of pasteurization was described by Louis Pasteur, who discovered that heating solutions to moderate temperatures would reduce the numbers of contaminating live microorganisms.
Many important biochemical reactions, such as energy generation, occur due to concentration gradients across membranes, creating a potential difference analogous to a battery.
Metabolism. The biochemical processes that sustain a living cell or organism.
Metallothionein. A protective protein that binds heavy metals, such as cadmium and lead.
Microbe. A microorganism.
A commensal bacterium inhabiting the human colon that is widely used in biology, both as a simple model of cell biochemical function and as a host for molecular cloning experiments. Ethidium bromide. A fluorescent dye used to stain DNA and RNA.
Amniocentesis -- prenatal diagnosis method using cells in the amniotic fluid to determine the number and kind of chromosomes of the fetus and, when indicated, perform biochemical studies. Amniocyte -- cells obtained by amniocentesis.
The goal in this course is to introduce the molecular and biochemical concepts necessary for understanding the biology of cells.
Auxotrophic mutantA bacterial strain which has a mutation in at least one of the enzymes in a biochemical pathway responsible for synthesising an essential substance, for example an amino acid.
The endoplasmic reticulum manufactures, processes, and transports a wide variety of biochemical compounds for use inside and outside of the cell.
For example, the science of biochemistry did not develop until well into the 20th century, however, the biochemical evidence of a common ancestor is perhaps the most compelling of all.
This character may be morphological, biochemical or molecular and must be fixed in reproductively cohesive units. It is important to realize that this reproductive continuity is not used in the same way as in the BSC.
The large-scale study of proteins, using biochemical or physical methods.

AraCyc Aracyc is a tool for querying and visualizing Arabidopsis biochemical pathways.Pathways can be browsed or searched by a variety of parameter such as reactions, compunds, genes and enzymes.
Physiology studies the mechanical, physical, and biochemical processes of living organisms, by attempting to understand how all the structures function as a whole.
This system controls many of the biochemical pathways that occur in your body. The core tool used by the endocrine system is a compound called a hormone.
A protein that acts as a catalyst, speeding the rate at which a biochemical reaction proceeds but not altering the direction or nature of the reaction.
