Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] Animal cells, plant cells and microorganism cells show similarities in their functions even though they vary in structure. [2] [page needed]
Physiology (/ ˌ f ɪ z i ˈ ɒ l ə dʒ i /; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία () 'study of') [1] is the scientific study of functions and mechanisms in a living system.
Glycolysis is an essential process of glucose degrading into two molecules of pyruvate, through various steps, with the help of different enzymes. It occurs in ten steps and proves that phosphorylation is a much required and necessary step to attain the end products.
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, [1] [2] [3] formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature mainly by processes of sprouting and splitting, but processes such as coalescent angiogenesis , [ 4 ] vessel elongation and ...
The cannabinoid receptor type 1, located at the presynaptic neuron, is a receptor that can stop stressful neurotransmitter release to the postsynaptic neuron; it is activated by endocannabinoids such as anandamide (N-arachidonoylethanolamide) and 2-arachidonoylglycerol via a retrograde signaling process in which these compounds are synthesized ...
The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used. [1]
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 ...
