monitta

Answer:

substrate-level phosphorylation

Explanation:

Substrate-level phosphorylation is the metabolic reaction which results in formation of energy currency molecules, ATP or GTP by direct transfer of a phosphoryl group to the ADP or GDP from the another phosphorylated compound.

<u>In citric acid cycle, Succinyl-CoA in the presence of succinyl-CoA synthase is converted to succinate. Condensation reaction (Substrate-level phosphorylation) of GDP and Pi takes place which results in the formation of GTP.</u>

Calculate the value of the diffusion coefficient D (in m2/s) at 547°C for the diffusion of some species in a metal; assume that
svetlana [45]

Answer : The value of diffusion coefficient is, 2.97\times 10^{-16}m^2/s

Explanation :

Formula used :

D=D_o\times \exp \left(-\frac{Q_d}{RT}\right )

where,

D = diffusion coefficient = ?

D_o = 5.6\times 10^{-5}m^2/s

Q_d = 177kJ/mol

R = gas constant = 8.314 J/mol.K

T = temperature = 547^oC=273+547=820K

Now put all the given values in the above formula, we get:

D=5.6\times 10^{-5}m^2/s\times \exp \left(-\frac{177kJ/mol}{(8.314J/mol.K)\times (820K)}\right )

D=2.97\times 10^{-16}m^2/s

Thus, the value of diffusion coefficient is, 2.97\times 10^{-16}m^2/s

bazaltina [42]
Atomic # 30
Atomic mass- 65.409g
Symbol- Zn
protons = electrons,
so 30 protons,30 electrons and 35 neutrons.
The atomic mass is also found by adding the protons and neutrons.
It can be found in group 12,period 4. Zinc is a transition metal.
Zinc has an oxidation state of 2+.
Melting point- 420 C
Boiling point- 907 C
Typical compounds formed are: zinc oxide, zinc sulfide and zinc nitrate.
According to records, a German scientists named Andreas Margraf discovered the element in 1746. Even though he was recognized for the discovery, historians agree ancient people created statues with some amount of zinc.
Zinc can be found in united states, Canada and Australia.

Hope this helps!
