Margaret Petherbridge Farrar (March 23, 1897 – June 11, 1984) was an American journalist and the first crossword puzzle editor for The New York Times (1942–1968). Creator of many of the rules of modern crossword design, she compiled and edited a long-running series of crossword puzzle books – including the first book of any kind that Simon & Schuster published (1924).

Eduard Buchner discovered cell-free fermentation. The component steps of glycolysis were first analysed by the non-cellular fermentation experiments of Eduard Buchner during the 1890s. [11] [12] Buchner demonstrated that the conversion of glucose to ethanol was possible using a non-living extract of yeast, due to the action of enzymes in the ...
The most frequent type of glycolysis found in the body is the type that follows the Embden-Meyerhof-Parnas (EMP) Pathway, which was discovered by Gustav Embden, Otto Meyerhof, and Jakob Karol Parnas. These three men discovered that glycolysis is a strongly determinant process for the efficiency and production of the human body.
The centrosome was discovered jointly by Walther Flemming in 1875 [1] [2] and Edouard Van Beneden in 1876. [3] [4] Flemming investigated the process of cell division and the distribution of chromosomes to the daughter nuclei, a process he called mitosis from the Greek word for thread. However, he did not see the splitting into identical halves ...
Cell division is the process by which a parent cell divides into two daughter cells. [1] Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing.
The former, often eponymously known as the "Krebs cycle", is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953.
By compartmentalizing glycolysis inside of the glycosome, the cell can be more successful. In the cell, action in the cytosol, the mitochondria, and the glycosome are all completing the function of energy metabolism. This energy metabolism generates ATP through the process of glycolysis. The glycosome is a host of the main glycolytic enzymes in ...
Christian René Marie Joseph, Viscount de Duve (2 October 1917 – 4 May 2013) was a Nobel Prize-winning Belgian cytologist and biochemist. [1] He made serendipitous discoveries of two cell organelles, peroxisomes and lysosomes, for which he shared the Nobel Prize in Physiology or Medicine in 1974 with Albert Claude and George E. Palade ("for their discoveries concerning the structural and ...
