Basic structure of a peroxisome Distribution of peroxisomes (white) in HEK 293 cells during mitosis Peroxisome in rat neonatal cardiomyocyte. A peroxisome (/ p ə ˈ r ɒ k s ɪ ˌ s oʊ m /) [1] is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells.
In 1974, however, Charles N. Serhan, Mats Hamberg and Bengt Samuelsson, discovered that human neutrophils metabolize arachidonic acid to two novel products that contain 3 hydroxyl residues and 4 double bonds viz., 5,6,15-trihydroxy-7,9,11,13-icosatetraenoic acid and 5,14,15-trihydroxy-6,8,10,12-icosatetraenoic acid.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
A second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965). Watson's version differs from Crick's because Watson describes a two-step (DNA → RNA and RNA → protein) process as the central ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Fisher's fundamental theorem of natural selection is an idea about genetic variance [1] [2] in population genetics developed by the statistician and evolutionary biologist Ronald Fisher. The proper way of applying the abstract mathematics of the theorem to actual biology has been a matter of some debate, however, it is a true theorem.
Condensed DNA often has surprising properties, which one would not predict from classical concepts of dilute solutions. Therefore, DNA condensation in vitro serves as a model system for many processes of physics, biochemistry and biology. [2] In addition, DNA condensation has many potential applications in medicine and biotechnology. [1]
The average rate of energy captured by global photosynthesis is approximately 130 terawatts, [6] [7] [8] which is about eight times the total power consumption of human civilization. [9] Photosynthetic organisms also convert around 100–115 billion tons (91–104 Pg petagrams, or billions of metric tons), of carbon into biomass per year.
