As you would expect, increasing the amount of substrate can increase the rate of the reaction, as long as the enzyme is not "saturated" already; conversely, adding enzymes can speed up a reaction at a given level of substrate, and can allow more substrate to be added without running up ...
have been identified as particularly important dietary contributors to dental caries14. Consumption of sweetened foodstuffs can rapidly increase the concentration of carbohydrates in the oral cavity, leading to a sharp decline in the pH values of biofilm to 4 or even lower15. Research has revealed...
107 CFU/ml) will hamper endpoint reading and increase the chances for false-negatives. Bacterial or yeast inoculates can be prepared from overnight cultures or from existing biofreeze stocks. It is recommended to collect from cultures during the logarithmic growth phase and always to take four or...
Fermentation involves the introduction of a number of microbes that increase the level of acid or alcohol;S.cerevisiaefermentation converts starch to simple sugars, which the yeast then consumes to create carbon dioxide and alcohol. Simply put, the yeast gorges on sugar as the cells reproduce. Th...
Biochemistry revealed a mildly increased serum lactate dehydrogenase (1.3× upper limit of normal [ULN]) and creatinine (1.4× ULN). She had an Eastern Cooperative Oncology Group (ECOG) performance score of 2. Question Should this patient receive intensive chemotherapy (ie, 7 + 3 plus or minus...
We performed TEVC experiments with IpaB-treated oocytes and showed that lowering the extracellular pH from 9.0 to 4.0 resulted in an increase of the inward-directed current measured at −100 mV (Figure 5b). The current amplitudes in untreated cells did not differ in this pH range (Figure 5b...
However, the moderate increase of the platelet count after switching to nonheparins indicated that HIT was probably not the only cause of thrombocytopenia. EIA, enzyme-immunoassay; HIPA, heparin-induced platelet activation assay; OD, optical density. Comment Analyzing carefully the platelet count cours...
Instead, research demand has spurred commercial vendors to increase supplies and improve practices, such as using microisolator rodent racks (Council, 2000). Like agriculture and aquaculture practices, commercial vendors and SPF research facilities adhere to bioexclusion practices with breeding, ...

Similarly, if a base is added to the solution, the base will react with the weak acid and there will be very little change to the pH. Answer and Explanation: 1 Become a Study.com member to unlock this answer! Create your account View this answer To increase the ...
