Alcohol

... the equilibrium to the right and produce a good yield of ester, water is usually removed, either by an excess of H 2 SO 4 or by using a Dean-Stark apparatus . Esters may also be prepared by reaction of the alcohol with an acid chloride in the presence of a base such as pyridine . Other types of ...

ATP synthase

... that pepper the inner mitochondrial membrane. They were originally called elementary particles and were thought to contain the entire respiratory apparatus of the mitochondrion, but through a long series of experiments, Ephraim Racker and his colleagues were able to show that this particle is correlated ...

Cisterna

... . For the Italian town, see Cisterna, Italy . A cisterna (plural cisternae ) comprises a flattened membrane disk which makes up the Golgi apparatus . A typical Golgi has anywhere from 3 to 7 cisternae stacked upon each other like a stack of dinner plates. The cisternae carry Golgi enzymes to ...

Dialysis

... what strength of fluid to use. Dialysis fluid typically comes premixed in a disposable bag-and-tube apparatus; no additional equipment is needed. The apparatus consists of two bags, one empty and one with the fluid, connected via flexible tubing to a Y-shaped fitting. The bag is heated to body temperature, ...

Endomembrane system

... The endoplasmic reticulum is a synthesis and transport organelle [the endoplasmic reticulum is an extension of the nuclear envelope]. The Golgi apparatus acts as the packaging and delivery system for molecules. Lysosomes are the "digestive" units of the cell. They utilize enzymes to break down ...

Myosin

... is composed of single muscle cells (sometimes known as "muscle fibers"). Within the cells are myofibrils ; the basic unit of a the contractile apparatus of a myofibril is the sarcomere , which is composed of three different filament systems, the thin filaments assembled by actin proteins, the ...

Peroxisome

... (the internal fluid of the cell). Peroxisomes were discovered by Christian de Duve in 1965 . Unlike lysosomes , which are formed in the Golgi apparatus , peroxisomes usually self-replicate by enlarging and then dividing, although there is some indication new ones may be formed directly. They also ...

Replication

... the genetic material of a cell ( DNA ) to a daughter cell is almost, but not quite, a form of self-replication because it requires the cellular apparatus to perform that replication. Semiconservative replication is the particular mechanism of DNA replication, of several mechanisms that were ...

Ribosome

... the ability of rRNA to synthesise protein. The structure and function of ribosomes, and their attendant molecules, known as the translational apparatus , has been of ongoing research interest since the mid 20th century on through the early 21st century. A triennial conference is held to discuss the ...

Species

... and certain biting ants). In the 18th century Carolus Linnaeus classified organisms according to differences in the form of reproductive apparatus . Although his system of classification sorts organisms according to degrees of similarity, it made no claims about the relationship between similar ...

Trait

... as it travels from the DNA in the Nucleus , to the Cytoplasm , to the Ribosomes and the Endoplasmic Reticulum , and finally to the Golgi apparatus , which may package the final products for export outside the cell. Cell products are released into the tissue , and organs of an organism , to ...

Vesicle

... the cell for organizing metabolism , transport, enzyme storage, as well as being chemical reaction chambers. Many vesicles are made in the Golgi apparatus , but also in the endoplasmic reticulum , or are made from parts of the plasma membrane . Lysosomes (membrane-bound digestive vesicles) can ...
