Only facilitated diffusion is a type of passive transport that uses carrier proteins. During facilitated diffusion, proteins move molecules across the cell membrane from high concentration to low concentration without using energy. Facilitated diffusion can use channel proteins, which allow for mass, non...

(TS) model4, called facilitated diffusion (FD), postulates that the search results from one-dimensional (1D) sliding events (with duration τ1D), during which proteins diffuse along nonspecific DNA sequences, interspersed with phases (with duration τ3D) of three-dimensional (3D) diffusion5,6....

One of the most important application areas of membrane transport proteins is exploring novel drugs for the treatment of infectious diseases. Most of the antibiotics target cell wall or protein synthesis and they are widely used for the treatment of diseases caused by pathogenic bacteria. However, ...
During depolarization, the inside of the neuron's membrane becomes less negative. Is the statement true or false? When oxygen accepts electrons at the end of the electron transport chain, it binds hydrogen atoms and water is produced. a. True b. False ...
Besides the broad applications of variousextracellular matrixproteins andpolysaccharidesin neural tissue engineering, nowadays, the extracellular matrix itself has been used as an appealing alternative to autograft. The extracellular matrix is composed of the interstitial matrix and thebasement membrane. The ...
As a first choice, we used X = Ig27WT (titin’s 27th immunoglobulin (Ig) domain, a well-studied mechanical protein model that has been independently characterized by single-molecule atomic force microscopy (AFM)43) and its two mutants, Ig27V13P and Ig27Y9P (ref. 40). The ...
Another line of (extracellular) annexin biology identified the proteins as inhibitors of blood coagulation, however here as effectors of the coagulation cascade and not as plasminogen activators. Hence, the name vascular (or also platelet) anticoagulant protein was also used for some annexins in the...
mori fibroin fibers in calvarial defects in mice facilitated the complete healing of the defect with new bone within 12 weeks [321]. Manually silked major ampullate silk fibers (from adult female spiders of the genus Nephila) have been used as a scaffold for nerve cell growth in vitro. ...
