Active transport n., [ˈæk.tɪv tɹænzˈpɔɹt] Definition: The “uphill” transport of substances Table of Contents Active transport is a type of cellular transport in which substances (e.g. ions, glucose, and amino acids) are transported across a biological membrane ...
Kristin has taught college Biology courses and has her doctorate in Biology. Definition and Significance of Active Transport Active transport is the movement of ions or molecules against their concentration gradient, which involves the input of chemical energy. This transport is carried out by integral...
Active Transport is the movement of molecules from a region of lower concentration to a region of higher concentration with the use of energy.
Radiation-use efficiency is a multidefinitional term. At the leaf level, radiation-use efficiency is often defined as the ratio between CO2 assimilation and absorbed photons. At the crop level, radiation-use efficiency can be defined as the ratio of dry matter production of the crop to be ...
Together, beaches and dunes act as a protective buffer against storms and sea-level rise, and, being interdependent through sediment transport and storage, removal of sand from one compartment affects the others. This zone is resilient as long as it remains free to fluctuate within its natural ...
This study finds that active acupoint treatment also reduces the level of cellobiose, which is fermented in the large intestine of humans46. Cellobiose is a prebiotic ingredient in fermented products involving bifidobacterial47. Gut microbiota, as a major part of the commensal microbiome in humans,...
Ranking the materials in a multiobjective optimization task introduces, by definition, a bias and detailed studies have been made to identify how such bias can impact the optimization (see ref. 35 and Supplementary Note 1). However, one can make a bias-free ranking of the experiments that ...
energy barriers associated with specific ligand transport paths. However, to ensure converged results (i.e., without any detectable trend in the observed variable upon further extension of simulation time), structures obtained by SMD can be used in a second biased simulation using a technique such...
However, the resolution may be limited by the large grain size in autoradiography and the build-up of a large antibody complex in immuno-EM, respectively. Another method used to follow the fate of isotopically labeled lipids consists of allowing transport processes to take place during a certain...
Self-organization is the generation of order out of local interactions. It is deeply connected to many fields of science from physics, chemistry to biology, all based on physical interactions. The emergence of collective animal behavior is the result of
