Robert Remak (26 July 1815 – 29 August 1865) was an embryologist, physiologist and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. [1] as well as several other key discoveries.
Glycolysis is the metabolic pathway that converts glucose (C 6 H 12 O 6) into pyruvate and, in most organisms, occurs in the liquid part of cells (the cytosol). The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). [ 1 ]
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.
Glycolysis results in the breakdown of glucose, but several reactions in the glycolysis pathway are reversible and participate in the re-synthesis of glucose (gluconeogenesis). [9] Glycolysis was the first metabolic pathway discovered: As glucose enters a cell, it is immediately phosphorylated by ATP to glucose 6-phosphate in the irreversible ...
The German-Polish physician Robert Remak suspected that he had already discovered animal cell division in the blood of chicken embryos in 1841, [56] but it was not until 1852 that he was able to confirm animal cell division for the first time in bird embryos, frog larvae and mammals. [57]
All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. [14] The activity of an organism depends on the total activity of independent cells. [15] Energy flow (metabolism and biochemistry) occurs within cells. Cells contain DNA which is found specifically in ...
U.S. scientists Victor Ambros and Gary Ruvkun won the 2024 Nobel Prize in Medicine on Monday for the discovery of microRNA and its crucial role in how multicellular organisms grow and live. Their ...
Philip Siekevitz (February 25, 1918 – December 5, 2009) was an American cell biologist who spent most of his career at Rockefeller University.He was involved in early studies of protein synthesis and trafficking, established purification techniques to facilitate study of the cell nucleus, worked with Nobel Prize in Physiology or Medicine winner George Palade on cell membrane dynamics, and ...
