  2. Anabolism - Wikipedia

    en.wikipedia.org/wiki/Anabolism

    Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids, which stimulate protein synthesis and muscle growth, and insulin.

  3. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    It occurs in ten steps and proves that phosphorylation is a much required and necessary step to attain the end products. Phosphorylation initiates the reaction in step 1 of the preparatory step [ 5 ] (first half of glycolysis), and initiates step 6 of payoff phase (second phase of glycolysis).

  4. Catabolism - Wikipedia

    Released from alpha cells in the pancreas either when starving or when the body needs to generate additional energy; it stimulates the breakdown of glycogen in the liver to increase blood glucose levels; its effect is the opposite of insulin; glucagon and insulin are a part of a negative-feedback system that stabilizes blood glucose levels ...

  5. Downregulation and upregulation - Wikipedia

    en.wikipedia.org/wiki/Downregulation_and_up...

    The complementary process that involves increase in quantities of cellular components is called upregulation. [ 1 ] An example of downregulation is the cellular decrease in the expression of a specific receptor in response to its increased activation by a molecule, such as a hormone or neurotransmitter , which reduces the cell's sensitivity to ...

  6. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    Complex II consists of four protein subunits and contains a bound flavin adenine dinucleotide (FAD) cofactor, iron–sulfur clusters, and a heme group that does not participate in electron transfer to coenzyme Q, but is believed to be important in decreasing production of reactive oxygen species.

  7. Biochemical cascade - Wikipedia

    Adenosine may have opposite effects on bone metabolism, because while certain purinergic receptors stimulate adenylyl cyclase activity, others have the opposite effect. [ 58 ] [ 59 ] Under certain circumstances adenosine stimulates bone destruction and in other situations it promotes bone formation, depending on the purinergic receptor that is ...

  9. Protein phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Protein_phosphorylation

    The p53 protein is heavily regulated [28] and contains more than 18 different phosphorylation sites. Activation of p53 can lead to cell cycle arrest, which can be reversed under some circumstances, or apoptotic cell death. [29] This activity occurs only in situations wherein the cell is damaged or physiology is disturbed in normal healthy ...
