An enzyme's specificity can be due to: Group of answer choices the ratio of catalyzed rate to the uncatalyzed rate of reaction. molecular recognition based on structural complementarity. amount of enzyme produced by the cell. amount of substrate available. metabolic activators.

Two things that biomedical has invented or innovated

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
