Acetylcholine binds to its receptor in the sarcolemma and triggers __________.

Chemistry
1 answer:
gladu [14]3 years ago
6 0

Answer:

b. The opening of ligand-gated cation channels

Step-by-step explanation:

When an acetylcholine ligand molecule binds to its receptor in the sarcolemma, it triggers a conformational change.

A "gate" in the receptor opens and allows Na⁺ ions to pass through a channel into the muscle fibre.

Hence the term ligand-gated cation channel.

Burning alcohol for fuel is a very efficient process. Please select the best answer from the choices provided
Vedmedyk [2.9K]
Burning alcohol for fuel has been used throughout history. There are some alcohols that are the best ones to use as fuels because of their nature and can be synthesized chemicaly or biologicaly. Except, some of those alcohol also has a bad effect when burned for fuel as it would cause serious negative chemical effects when exposed to the human body such as blindness or death. Therefore, the best answer would be False.

At equilibrium, the concentrations of the products and reactants for the reaction, H2 (g) + I2 (g)  2 HI (g), are [H2] = 0.106
lana [24]

Answer:

The new equilibrium concentration of HI: <u>[HI] = 3.589 M</u>          

Explanation:

Given: Initial concentrations at original equilibrium- [H₂] = 0.106 M; [I₂] = 0.022 M; [HI] = 1.29 M        

Final concentrations at new equilibrium- [H₂] = 0.95 M; [I₂] = 0.019 M; [HI] = ? M

<em>Given chemical reaction:</em> H₂(g) + I₂(g) → 2 HI(g)

The equilibrium constant (K_{c}) for the given chemical reaction, is given by the equation:

K_{c} = \frac {[HI]^{2}}{[H_{2}]\: [I_{2}]}

<u><em>At the original equilibrium state:</em></u>

K_{c} = \frac {(1.29\: M)^{2}}{(0.106\: M) \times (0.022\: M)}

K_{c} = \frac {1.6641}{0.002332} = 713.59

<u><em>Therefore, at the new equilibrium state:</em></u>

K_{c} = \frac {[HI]^{2}}{(0.95\: M) \times (0.019\: M)}

\Rightarrow K_{c} = 713.59 = \frac {[HI]^{2}}{0.01805}

\Rightarrow [HI]^{2} = 713.59 \times 0.01805 = 12.88

\Rightarrow [HI] = \sqrt {12.88} = 3.589 M

<u>Therefore, the new equilibrium concentration of HI: [HI] = 3.589 M</u>

Calculate the rcf (recipe conversion factor) for a new yield of 80 oz. (5 lbs) blueberry muffin batter. the original yield of th
SCORPION-xisa [38]

The rcf (recipe conversion factor)=  0.6

<h3>What is the rcf (recipe conversion factor)?</h3>
  • The conversion factor approach is the most typical technique for modifying recipes.
  • Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
  • Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
  • The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.
  • The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).

How this is calculated?

Conversion Factor = New Yield ÷ Old Yield

 =80/134

 =0.5970

 =0.6(rounded to nearest tenth)
