An aminoacyl-trna that enters the a site of the ribosome will next occupy which site?

Physics
1 answer:
kkurt [141]3 years ago
5 0

Answer:

The P site

Explanation:

After the formation of peptide linkage, the trna of P site becomes free, more to the E site and then slip away. The A site trna has dipeptide instead of a single aminoacid.

In the prescence of translocase and energy from GTP, the ribosome move in such a way the peptidyl bearing trna of A site come to lie with P sit. This exposes next codon to A site. A new aminoacid trna complex reaches the fresh codon exposed at A site.

A 477 g portion of soup is heated in a microwave oven from 25°C to 90°C, using radiation with a wavelength of 1.55 × 10⁻² m. Ass
zheka24 [161]

To solve this problem we will use the heat transfer equations, to determine the amount of heat added to the body. Subsequently, through the energy ratio given by Plank, we will calculate the energy of each of the photons. The relationship between total energy and unit energy will allow us to determine the number of photons

The mass of water in the soup is 477g

The change in temperate is

\Delta T = (90+273K)-(25+273K) = 65K

Use the following equation to calculate the heat required to raise the temperature:

q = mc\Delta T

Here,

m = Mass

c = Specific Heat

q = (477)(4.184)(65)

q = 129724.92J

The wavelength of the ration used for heating is 1.55*10^{-2}m

The number of photons required is the rate between the total energy and the energy of each proton, then

\text{Number of photons} = \frac{\text{Total Energy}}{\text{Energy of one Photon}}

This energy of the photon is given by the Planck's equation which say:

E = \frac{hc}{\lambda}

Here,

h = Plank's Constant

c = Velocity of light

\lambda = Wavelength

Replacing,

E = \frac{(6.626*10^{-34})(3*10^8)}{1.55*10^{-2}}

E = 1.28*10^{-23}J

Now replacing we have,

\text{Number of photons} = \frac{82240.7}{1.28*10^{-23}}

\text{Number of photons} = 6.41*10^{27}

Therefore the number of photons required for heating is 6.41*10^{27}

A metal begins to emit electrons, as measured in an apparatus similar to the one Hertz used, when exposed to light at a waveleng
balandron [24]

Answer : The work function of this metal is, 5.81\times 10^{-19}J

Explanation : Given,

Wavelength of light = 342nm=342\times 10^{-9}m

Formula used :

E=h\nu_o=\frac{hc}{\lambda}

where,

E = work function of metal

h = Planck's constant = 6.626\times 10^{-34}Js

\nu_o = threshold frequency

\lambda = wavelength of light

c = speed of light = 3\times 10^8m/s

Now put all the given values in this formula, we get the value of work function of this metal.

E=\frac{hc}{\lambda}

E=\frac{(6.626\times 10^{-34}Js)\times (3\times 10^8m/s)}{(342\times 10^{-9}m)}

E=5.81\times 10^{-19}J

Therefore, the work function of this metal is, 5.81\times 10^{-19}J
