Active Transport Definition Active transport is a kind of cellular transport where substances move against a concentration gradient. This means that the direction is from an area of lower concentration to an area of higher concentration. Hence, this process will require the expenditure of energy, and...
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.
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 ...

While this interpretation of physical interactions may also be valid, we restrict our definition of information based interactions to situations, where the physical interactions are irrelevant. In the well-known thought experiment of Maxwell, for example, a small daemon uses the information on the ...
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,...
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...
An interesting detail concerns the possible occurrence of ‘head’ addition,i.e.addition of a radical to the substituted end of thedouble bondin the monomer. This was shown to occur at the 20% level withvinyl acetateat 60°C and to a greater extent at 100°C, but to be absent in the...
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 ...
