- Ion and lipid orchestration of secondary active transport
Together, ion gradients and lipid properties ensure the effective transport, regulation and distribution of small molecules across cell membranes Small molecule transporters catalyse the
- The behavior, transport, and positive regulation mechanism of ZnO . . .
In this review, we describe the transport and transformation processes of ZnO NPs (via soil or foliar application), and we summarize the positive influence of ZnO NPs on plants at the physiological and molecular levels
- Physiology, Active Transport - StatPearls - NCBI Bookshelf
There are 2 main modes of transport of molecules across any biological membrane These are passive and active transport Passive transport, most commonly by diffusion, occurs along a high-to-low concentration gradient No energy is necessary for this mode of transport
- Cell Membrane Transport Mechanisms: Ion Channels and Electrical . . .
Membrane proteins play a crucial role in ensuring selective transport of molecules across the membrane as well as controlling interactions between cells They can act as ion channels, pumps, receptors, enzymes, or energy transducers
- positive regulation of transport - Gene Ontology
Any process that activates or increases the frequency, rate or extent of the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore Source: GOC:ai Chem react
- positive regulation of transport - EMBL-EBI
Any process that activates or increases the frequency, rate or extent of the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore
- Regulation of ion transport from within ion transit pathways
Ion transporters can be strongly regulated by autoinhibitory reactions that depend on ion binding within their transport sites All cells must control the activities of their ion channels and transporters to maintain physiologically appropriate gradients of solutes and ions
- Signaling Mechanisms That Regulate Glucose Transport
Insulin, the major hormonal regulator of glucose transport in humans, has served as a prototypic molecule for understanding cell signaling pathways since its discovery in 1922 It was among the first proteins for which primary amino acid sequence and three-dimensional structure were determined
