ect (5) 썸네일형 리스트형 pH dependent binding site transition of enzyme All biological processes are in some way pH-dependent. Human bodies and those of other organisms need to maintain specific and constant pH regulation in order to function. Changes in pH can have serious biological consequences—or serious benefits. Cellulosomes are extracellular complexes consisting of multiple enzymes, which are associated with the cell's surface. Within the cellulosome cellular.. do fish school reduce energy cost of swimming? Do fish save energy by swimming in schools? Now, scientists from the Max Planck Institute of Animal Behavior (MPI-AB), the University of Konstanz, and Peking University have provided an answer that has long been suspected but never conclusively supported by experiments: yes. Using biomimetic fish-like robots, the researchers show that fish could take advantage of the swirls of water generated by.. pericytes들을 연결해주는 cell structure we have identified a communication structure between cells that is required to coordinate blood supply in the living retina, "We already knew that activated retinal areas receive more blood than non-activated ones," she said, "but until now no one understood how this essential blood delivery was finely regulated." Wrapped around the capillaries are pericytes, cells that have the ability to contr.. how to overcome coffee ring effect the coffee ring effect. This effect has hindered the industrial deployment of functional inks with graphene, 2-D materials, and nanoparticles because it makes printed electronic devices behave irregularly. Now, after studying this process for years, a team of researchers have created a new family of inks that overcomes this problem, enabling the fabrication of new electronics such as sensors, li.. 세포 스트레스로 인한 리보솜 충돌에 따른 cell fate When cells experience a high level of stress—for example, when they are exposed to too much UV light—ribosomes inside the cell collide and get into traffic jams. Now, Johns Hopkins scientists have found a protein that recognizes this traffic problem and pushes the cell down a path toward cell suicide. Molecular biologist Rachel Green, Ph.D., and her team have long been studying how cells recogni.. 이전 1 다음
