  2. Adenosine - Wikipedia

    en.wikipedia.org/wiki/Adenosine

    Adenosine is a key factor in regulating the body's sleep-wake cycle. [40] Adenosine levels rise during periods of wakefulness and lowers during sleep. Higher adenosine levels correlate with a stronger feeling of sleepiness, also known as sleep drive or sleep pressure. [41]

  3. Anaerobic exercise - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_exercise

    The biochemistry of anaerobic exercise involves a process called glycolysis, in which glucose is converted to adenosine triphosphate (ATP), the primary source of energy for cellular reactions. [3] Anaerobic exercise may be used to help build endurance, muscle strength, and power. [4] [5]

  4. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...

    Except for PP i → 2 P i, these reactions are, in general, not allowed to go uncontrolled in the human cell but are instead coupled to other processes needing energy to drive them to completion.

  6. Nicotinamide adenine dinucleotide - Wikipedia

    en.wikipedia.org/wiki/Nicotinamide_adenine_di...

    Nicotinamide adenine dinucleotide consists of two nucleosides joined by pyrophosphate.The nucleosides each contain a ribose ring, one with adenine attached to the first carbon atom (the 1' position) (adenosine diphosphate ribose) and the other with nicotinamide at this position.

  7. Adenosine diphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_diphosphate

    Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose .

  8. Adenosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_triphosphate

    Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the "molecular unit of currency" for intracellular energy transfer. [3]

  9. ATP hydrolysis - Wikipedia

    en.wikipedia.org/wiki/ATP_hydrolysis

    Structure of ATP Structure of ADP Four possible resonance structures for inorganic phosphate. ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released after splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.
