When all the enzyme is complexed with substrate, there can be no further increase in the rate of the reaction as more substrate is added. The system reaches its maximum velocity. In mediated diffusion, we can again assume that the substrate combines with the carrier to form a complex and, ...
Accurate label-free methods or assays to obtain the initial reaction rates have significant importance in fundamental studies of enzymes and in application-oriented high throughput screening of enzyme activity. Here we introduce a label-free approach for obtaining initial rates of enzyme activity from h...
In addition, we must include the effects of the kinetics of the electrochemical reaction at the electrode/electrolyte interface. This can be done via the characteristic time associated with the reaction, tc, which can be calculated via the Butler–Volmer equation20...
For measurements of glycolysis, reactions were stopped with 1 N HCl, and D-[3-3H] glucose was separated from tritiated [3H]2O (generated from dehydration at enolase in glycolytic reaction) by diffusion. Samples were counted using a LS 6500 Multi-purpose Scintillation Counter (Beckman Coulter...
we must include the effects of the kinetics of the electrochemical reaction at the electrode/electrolyte interface. This can be done via the characteristic time associated with the reaction,tc, which can be calculated via the Butler–Volmer equation20, and can range from ~0.1 to >100 s ref...
Motion perception is affected by healthy aging, which impairs the ability of older adults to perform some daily activities such as driving. The current study investigated the underlying causes of age-related motion contrast sensitivity losses by using an
It is not known whether the likelihood of pregnancy after transfer of cryopreserved equine in vitro produced (IVP) blastocysts is related to post-thaw morphological characteristics, or could be impacted by other factors such as embryo biopsy prior to cryopreservation. This study examined associations ...
Another object of the present invention to provide a fast repetition rate flasher for use in a fluorometer that can independently measure the Plastoquinou (PQ)-pool size and the concentration of PSII reaction centers, in phytoplankton and higher plants. Yet another object of the present invention...
