Answer:The ratio of the concentrations of 
and 
when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid = 
Concentration of HA= 0.5 mM
Concentration of = 0.1 mM
pH = 6.16
First we have to calculate the value of 
.
Using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[A^-}{[HA]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BA%5E-%7D%7B%5BHA%5D%7D)
Now put all the given values in this expression, we get:
![6.16=pK_a+\log (\frac{[0.1]}{0.5})](https://tex.z-dn.net/?f=6.16%3DpK_a%2B%5Clog%20%28%5Cfrac%7B%5B0.1%5D%7D%7B0.5%7D%29)
To calculate the ratio of the concentrations of and when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
![7.02=6.86+\log \frac{[A^-]}{[HA]}](https://tex.z-dn.net/?f=7.02%3D6.86%2B%5Clog%20%5Cfrac%7B%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
![\frac{[A^-]}{[HA]}=1.44](https://tex.z-dn.net/?f=%5Cfrac%7B%5BA%5E-%5D%7D%7B%5BHA%5D%7D%3D1.44)
![\frac{[HA]}{[A^-]}=0.69](https://tex.z-dn.net/?f=%5Cfrac%7B%5BHA%5D%7D%7B%5BA%5E-%5D%7D%3D0.69)
Thus the ratio of the concentrations of and when the buffer has a pH of 7.02 is 0.69
Answer:
cause the chromosomes are divided in meiosis-1 in pachytene phase
Explanation:
The answer is letter C. ATP.
<span>
ATP stands for Adenosine Triphosphate which is present in every cell’s
cytoplasm and nucleoplasm which is essential in all the physiological
mechanisms. It is considered as the energy currency of life or the “molecular
unit of currency”. It stores the energy
that we need every day to do our daily undertakings. The primary function of
ATP is to transport chemical energy within the body cells for metabolism. It is
said that 1 moleculte of ATP is composed of 3 phosphate groups.</span>
Answer:
B) energy is captured in the bonds linking amino acids that compose lipase.
Explanation:
Anabolic reactions are chemically defined as synthesis reactions in opposition to Catabolic reactions, in which a degradation of chemical compounds occurs. Thus, in anabolic transformations simpler reagents are used to produce more complex substances. In the particular case of the synthesis of a lipase, a number of amino acids are chemically bonded to form a polymerized structure, clearly chemically more complex, known as polypeptide.
An increase in chemical complexity always requires an investment of energy, considering that building a larger molecule implies bonding more reagents or precursor into the final product. Thus, the increase in the energy content of the product (in this case the lipase) when comparing to each precursor (individuals amino acids) will be reflected in the linking (covalent) bonds between amino acids. Of course, there is always a certain amount of energy that is lost as heat during any chemical transformation (not all the energy invested in the synthesis will be captured in the product).
The overall of all anabolic reaction which take place inside the cell is called anabolism, while the whole set degradation chemical reaction occurring within the cell is known as catabolism. Being said that, it is clear that anabolism and catabolism, when being considered jointly, conform the metabolism as a whole and coordinated cellular process.
