What alteration to an HCN channel will reduce the transport of K+ in favor of Na+ transport? HCN channels are permeable to both

K+ and Na+ ions.
Chemistry
1 answer:
kipiarov [429]3 years ago

Answer:

Decreasing the diameter of the channel by removing aa's. Since Na+ is chemically similar to K+, one can assume the difference must be due to the size of the atom. The K+ ion is larger than the Na+ ion, so reducing the diameter of the channel can allow Na+ to enter while preventing K+ entry. This explains clearly and perfectly how reducing the diameter reduces the

transport of K+ in favor of Na+ transport.

A) Draw three structures of 3 sulfur containing acids. Minimize formal charges by expanding sulfur's octet . Include any nonbond
Sedbober [7]

You may find the structure of compounds as well the oxidation number of sulfur in each compound written with blue color. The nonbonded electrons are represented by black dots.

Explanation:

In the methyl sulfenic acid sulfur have a oxidation number of 0, because we have +1 from carbon and -1 from hydroxil group.

In the methyl sulfinic acid sulfur have a oxidation number of +2 , because we have +1 from carbon, -1 from hydroxil group and -2 from oxygen.

In the  methyl sulfonic acid sulfur have a oxidation number of +4 , because we have +1 from carbon, -1 from hydroxil group, -2 from one oxygen and -2 form the other oxygen.

mezya [45]

Answer:

Label A - Radio waves

Label C - Infrared

Label D - Visible light

Label G- Gamma rays

Explanation:

  • Electromagnetic spectrum is an arrangement of electromagnetic waves in order of their varying frequencies and wavelengths,
  • Radiowaves have the highest wavelength and lowest frequency while the gamma rays have the lowest wavelength and the highest frequency.
  • In order of increasing wavelength and decreasing frequency the electromagnetic waves are; Gamma rays, X-rays, U.V light, Visible light, infrared waves, microwaves, and Radio waves.

How many grams of O₂ are required to react completely with 14.6 g of Na to form sodium oxide, Na₂O?
Bad White [126]

The balanced chemical reaction is :

O_2 + 4Na \ -> \ 2Na_2O

Number of moles of Na, n = \dfrac{14.6}{23} = 0.635 \  mol .

Now, from balance chemical reaction we can see that 1 mole of oxygen reacts with 4 moles of sodium.

So, number of moles of oxygen are :

n = \dfrac{0.635}{4}\  mole

So, amount of oxygen required is :

m = \dfrac{0.635 \times 32}{4}\  gm\\\\m = 5.08 \ gm

Therefore, 5.08 gram of oxygen will react with 14.6 gram of sodium.

hydrogen and oxygene react to form water l. How many molecules of O2 are required to produce 0.6 of H20​
user100 [1]

Answer:

It is required 0.3 molecules of O2 to produce 0.6 molecules of H2O

Explanation:

The water´s formation reaction is: 2H2 + O2 --> 2H2O

This reaction shows the molecular O2:H2O ratio: 1:2.

Then, if we want to know how many molecules of O2 are required to produce 0.6 of H20​, it is necessary calculate as it showed next:

0.6 molecules H2O * (1 molecula O2 / 2 molecules H2O)= 0.3 molecule O2
