The addition of phosphate to a chemical compound is called A. glycolysis. B. oxidation. C. reduction. D. phosphorylation.
stich3 [128]

Answer:

Option (D)

Explanation:

Phosphorylation can be simply defined as the addition of a phosphate group to an organic and inorganic molecule. This process helps in regulating the processes that occur in the cells. It leads to the growth and development of cells and this process is efficiently carried out with the help of enzymes like kinase. It also plays an important role in transferring the signals within the cells, synthesis, and functioning of proteins within the cells, and storing as well as releasing of energy.

Thus, the correct answer is option (D).

Un gas ocupa un volumen de 12 litros a una presión de 912 mm Hg. Si permanece constante la temperatura, ¿A qué presión el gas oc
adoni [48]

Answer:

The  pressure occupied is 1, 8 atm.

Explanation:

We use the Boyle´s Mariotte ´s law: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1= P2xV2. The unit of pressure is converted to mmHg in atm.

760 mmHg----1 atm

912 mmHg---x= (912 mmHg x 1 atm)/760 mmHg=1,2 atm

P1xV1= P2xV2

P2=P1xV1/V2= 1,2 atm x 12 L/ 8L= <em>1, 8 atm</em>

Would the N=O bond in HNO2 be longer, shorter, or the same length as the N-O bonds in NO2-?
aivan3 [116]

Explanation:

Bond order is inversely proportional to the bond length.

B.O\propto \frac{1}{B.L}

In HNO_2 molecule. one nitrogen is double bonded to nitrogen and one oxygen is single bonded to nitrogen and hydrogen bond.

  • Bond order between the (N=O) bond is 2 which means that bond length between the (N=O) bond is shorter than that of the N-O bond.
  • Bond order between the (N-O) bond is 1 which means that bond length of the N-O bond is longer than that of the bond length of (N=O) bond.
