During the light-dependent reactions, electrons within pigment molecules found embedded in photosynthetic membranes are excited, and this energy is transferred between pigment molecules until one of those molecules loses its high-energy electron to an...
Only those cyanobacteria that were able to produce molecules to scavenge oxygen and nitrogen free radicals (ROS and NOS) were able to survive that catastrophe. Indeed, melatonin likely played an essential role those days, effectively protecting organisms from the oxidative stress...
[24] used the quantitative trait locus approach to show that the circadian clock gene period and pigment dispersion factor receptor differ in allele frequency among populations with one or two generations. Moreover, studies on two populations of CBW with differing diapause phenotypes have unveiled a...
which also contain chlorophyll—a green pigment in plants (stored in the thylakoid) that is able to capture light energy from the sun. The mesophyll is the middle layer of cells in a leaf, and most of the chloroplast are located in the upper region (the palisade layer)...
Located in neurons, vesicles are small sacs that store neurotransmitters, like acetylcholine. Botox targets and breaks down the proteins that help these vesicles release acetylcholine, preventing it from being released into the space between the nerve and the muscle. This prevention of muscle ...

(A–C) During the pre-organoid stage, the retinal cells were induced by transplanting NPCs/RPCs into the retina in vivo, misexpressing retinal transcription factors in the ESCs/iPSCs, or culturing these cells with proper signaling molecules. (A) NPCs purified from the adult rat hippocampus ...
