The glycerol phosphate shuttle was first characterized as a major route of mitochondrial hydride transport in the flight muscles of blow flies. [5] [6] It was initially believed that the system would be inactive in mammals due to the predominance of lactate dehydrogenase activity over glycerol-3-phosphate dehydrogenase 1 (GPD1) [5] [7] until high GPD1 and GPD2 activity were demonstrated in ...
In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time. The role of genes in pattern formation is an aspect of morphogenesis , the creation of diverse anatomies from similar genes, now being explored in the science of evolutionary developmental biology or evo-devo.
2,3-BPG is formed from 1,3-BPG by the enzyme BPG mutase.It can then be broken down by 2,3-BPG phosphatase to form 3-phosphoglycerate.Its synthesis and breakdown are, therefore, a way around a step of glycolysis, with the net expense of one ATP per molecule of 2,3-BPG generated as the high-energy carboxylic acid-phosphate mixed anhydride bond is cleaved by 2,3-BPG phosphatase.
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism.
[12] Evidence shows that APC3 and APC7 serve to recruit Cdh1 to the anaphase-promoting complex. [13] This further supports that Cdh1 is responsible for maintaining APC activity during G1. Cdh1 does not require APC to be phosphorylated in order to bind, in fact, phosphorylation of Cdh1 by Cdks prevents it from binding to APC from S to M phase.
[12] Effector neurons can be used to refer to population of neurons in the nervous system, which are responsible for a certain brain function. An example are the neurons in the mesopontine tegmental anesthesia area (MPTA) of the brainstem, which have been mapped as the region of the brain that is responsive to anaesthetics in a rodent model.

Molecular machines are a class of molecules typically described as an assembly of a discrete number of molecular components intended to produce mechanical movements in response to specific stimuli, mimicking macromolecular devices such as switches and motors.
The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3. Cell division is the process by which a parent cell divides into two daughter cells. [1] Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing.
