This biology movie centers around the life of Louis Pasteur, one of the progenitors of the disciplines of Microbiology and Immunology.Despite working at the time when the study of the microbial world was poorly appreciated, Pasteur was able to come up with the process called “pasteurization“. Most importantly, the mean net effects … Here is the Earth - from the International Space Station. In biochemistry, an effector molecule is usually a small molecule that selectively binds to a protein and regulates its biological activity.In this manner, effector molecules act as ligands that can increase or decrease enzyme activity, gene expression, or cell signaling.Effector molecules can also directly regulate the activity of some mRNA molecules (riboswitches). American Journal of Human Biology. Here, we define a reversal as occurring when the net impact of two stressors is in the opposite direction (negative or positive) from that of the sum of their single effects.
