Individual retirement account. An individual retirement account [1] ( IRA) in the United States is a form of pension [2] provided by many financial institutions that provides tax advantages for retirement savings. It is a trust that holds investment assets purchased with a taxpayer's earned income for the taxpayer's eventual benefit in old age.
In the United States, a 401 (k) plan is an employer-sponsored, defined-contribution, personal pension (savings) account, as defined in subsection 401 (k) of the U.S. Internal Revenue Code. [1] Periodic employee contributions come directly out of their paychecks, and may be matched by the employer. This pre-tax option is what makes 401 (k) plans ...
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Equifax. Equifax Workforce Solutions, formerly known as TALX (pronounced "talks"), is a wholly owned subsidiary of Equifax. [1] [2] [3] It is based in St. Louis, Missouri. [4] The company was originally founded in 1972 under the name Interface Technology Inc. The company maintains a database named "The Work Number" that holds and maintains ...
ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. [1] [2] It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. [3] [4] Improper ADP-ribosylation has been implicated in some forms of cancer. [5]
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their activities.
Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. The electron transport chain in the cell is the site of oxidative phosphorylation. The NADH and succinate generated in the citric acid cycle are oxidized, releasing the energy of O 2 to power the ATP synthase.
ATP is initially bound to myosin. When ATPase hydrolyzes the bound ATP into ADP and inorganic phosphate, myosin is positioned in a way that it can bind to actin. Myosin bound by ADP and P i forms cross-bridges with actin and the subsequent release of ADP and P i releases energy as the power stroke. The power stroke causes actin filament to ...
