TCA Cycle
The TCA Cycle (== Template:IPA ==
The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.
Related Terms
- Phonetic notation: A system used to visually represent the sounds of speech. The IPA is one type of phonetic notation.
- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form. In linguistics, this is often done using the IPA.

polski, also known as the Citric Acid Cycle or the Krebs Cycle), is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins, into adenosine triphosphate (ATP) and carbon dioxide.
Etymology
The TCA Cycle is named after Hans Adolf Krebs, the biochemist awarded the Nobel Prize in Physiology or Medicine in 1953 for his discovery. TCA stands for Tricarboxylic Acid Cycle, another name for the cycle due to the involvement of citric acid, a tricarboxylic acid, in the cycle.
Process
The TCA Cycle begins with the condensation of acetyl-CoA with oxaloacetate to form citrate, catalyzed by the enzyme citrate synthase. This is followed by a series of reactions that lead to the regeneration of oxaloacetate, completing the cycle. The cycle involves eight steps and is controlled by eight different enzymes.
Related Terms
- Acetyl-CoA: A molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. Its main function is to deliver the acetyl group to the citric acid cycle to be oxidized for energy production.
- Oxaloacetate: A four-carbon molecule that combines with acetyl CoA to form citrate in the first step of the TCA Cycle.
- Citrate: A molecule that is the product of the first step of the TCA Cycle and is further processed in subsequent steps.
- ATP: Adenosine triphosphate, a complex organic chemical that provides energy to drive many processes in living cells.
