<u>Solu</u><u>tion</u><u> </u><u>:</u><u>-</u>

In biology the word <em>bio</em><em> </em><em>catylysts</em><em> </em>describes the word enzymes . Bio catylysts are nothing but enzymes which alter the rate of reaction . For ex - Pepsinogen , which is produced in the stomach of humans activated by HCl from a proenzyme called trypsin . It works in acidic medium and converts proteins into peptides and protons . Likewise there is another enzyme called Salivary amylase which is present in the saliva of humans converts starch into maltose . There is another enzyme called lipase which converts fats into fatty acids and glycerol .

A certain buffer is made by mixing a weak acid HA and its conjugate base A–. When HA is present at a concentration of 0.5 mM and
MAVERICK [17]

Answer:The ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02 is 0.69

Explanation:

The dissociation constant for formic acid = K_a=1.8\times 10^{-4}

Concentration of HA= 0.5 mM

Concentration of A^-= 0.1 mM

pH = 6.16

First we have to calculate the value of K_a.

Using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[A^-}{[HA]}

Now put all the given values in this expression, we get:

6.16=pK_a+\log (\frac{[0.1]}{0.5})

pK_a=6.86

To calculate the ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02.

Using Henderson Hesselbach equation :

7.02=6.86+\log \frac{[A^-]}{[HA]}

7.02=6.86+\log \frac{[A^-]}{[HA]}

\frac{[A^-]}{[HA]}=1.44

\frac{[HA]}{[A^-]}=0.69

Thus the ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02 is 0.69

What bases pair with the following sequence in DNA: TAGCGTACTGAG
mafiozo [28]

Correct option is AUCG

Adenine base pairs up with the thymine while guanine pairs with cytosine. In RNA thymine is replaced by uracil, therefore adenine pairs up with uracil. In the given sequence TAGC, the complementary sequence would be AUCG.

So, the correct option is 'AUCG'.
