-proteins help substance diffuse across membrane -speeds process Osmosis -diffusion of water Isotonic Solution -same concentration of solute as cell -movement of water in both directions Hypotonic Solution -less concentration of solute than cell (more water) ...
17.Passive diffusion: In this process, transport across a cell membrane depends on the concentration gradient of the solute.被动扩散在被动扩散过程中,跨细胞转运依赖于溶质浓度梯度。 18.Transportation Cost Inequalities and Uniqueness of Semigroups Generated by Diffusion Operators;传输不等式及扩散算子生成半...
Nutrient sensing and transport acrossbiologicalmembranes is a vital process for cell homeostasis and long-term survival. Unravelling the molecular mechanisms underlying the control of solutes across biological membranes is an important focus of fundamental and applied research. Membrane nutrient transporters a...
Black-box modeling of proton exchange membrane fuel cell generators Proton exchange membranes are one of the most promising fuel cell technologies for transportation applications. Considering this aim, a simulation model of... S Jemei,D Hissel,MC Pera,... - Conference of the IEEE Industrial Elec...

antiport, uniport, and symport. antiport proteins exchange the solutes by transporting them in and out of the cell. the main function of uniport protein is to carry single solute across the membrane. symport proteins transfer two different solutes simultaneously in the same direction. also ...
the fuel cell at the anode, where they are split into protons and electrons. The protons pass through the membrane to the cathode, while the electrons flow through an external circuit, generating electricity. At the cathode, the protons, electrons, and oxygen combine to produce water and heat...
Proton Exchange Membrane Electrolyzer Cell PV Photovoltaic RES Renewable Energy Sources WT Wind Turbine Introduction The harmful impact of fossil fuels consumption on the environment due to their global warming potential has led to an unsustainable climate change situation. Thus, it is necessary to trans...
PⅠ could specifically permeate into MDA-MB-231 cells.Conclusion GST-PⅠ,a fusion protein with expected molecular mass,was expressed.PⅠ can mediate the fusion proteins across the cell membrane.It can be used as a targeting vector to delivery bimolecular agent in gene therapy of breast cancer....
