(i) The diffusion rate depends on the size of the substrate. (ii) Diffusion across the membrane depends upon its solubility in lipids. (iii) Membrane protein provides sites for a hydrophilic substance to cross the membrane. (iv) Facilitated diffusion is carried out by Proteins . Doubtnut is ...
The diffusion rate in a Mather problem or in geodesic flow on a two-dimensional torus that is perturbed by a time-periodic potential is discussed. The Mather problem is influenced by a time-periodic potential. The separatirix map and the anti-integrable limit are applied, and the estimation ...
diffusion In the process of diffusion of a single solute, a concentration of molecules on one side of a membrane (top) will move through a membrane (center) until there is equilibrium on both sides (bottom). dif·fu·sion (dĭ-fyo͞o′zhən) ...
The rate of diffusion varies with the type of technology and is determined by the degree of difficulty of transfer. The costs of transferring the technology increase with the difficulty. 相关知识点: 试题来源: 解析 技术由于类型的不同,扩散速度也不同,它由转让的难度所决定。技术转让的难度越大成...
For this reason, diffusion penetration is considerably slower than free motion (for example, the rate of diffusion propagation of odors is much lower than the speed of the molecules). Displacement of the particle changes in time in a random manner, but its mean square L̅2 increases over a...
At first glance, our observation that IDR5del is less sensitive to cytoskeleton-transmitted forces than full-length PIEZO2 while both channels show similar lateral diffusion characteristics, argues against this hypothesis. It is, however, possible that IDR5 is merely required for the PIEZO2 ...
To solve the problem of finding the density ratio of substances A and B given that the rate of diffusion of A is 10 times that of B, we can follow these steps:1. Understand the relationship between rate of diffusion and density
3 (a) Different gases diffuse at different speeds.(i) What is meant by the term diffusion?[1(ii) What property of a gas molecule affects the speed at which it diffuses?[1(b)Helium is a gas used to fill balloons. It is present in the air in very small quantities. Diffusion can b...
The rate of effusion of a gas is inversely proportional to the square root of its molar mass; lighter gases effuse more quickly. 13 What distinguishes diffusion from effusion? Diffusion involves the spread of particles from an area of high concentration to low, while effusion involves gas escapin...
