During a conversation with a friend, you tell him that you recently learned in your biology class that acetylcholine release by

a motor neuron triggers an action potential in a muscle fiber, causing it to contract. Your friend tells you that he heard that Botox injections into facial muscles underlying the skin inhibit contraction of the muscles that cause a particular type of facial wrinkle. He asks how Botox does this. What will you tell him

Answer:

Explanation:

Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species

Botulinum toxin commonly acts by binding to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. Through this mechanism, muscle movement is inhibited in the area it is injected to.

Calculate the percentage ionization in these amino acid side chains at the ph values specified:
Margarita [4]

The <u>Henderson-Hasselbalch equation</u> and pKa can be used to determine the % ionization if it is assumed that the amino and carboxyl groups are not preventing ionization.

  1. aspartate at ph 5.4 = 98.3%
  2. glutamate at ph 11.8 = 100%
  3. histidine at ph 8.0 = 99%

Henderson-Hasselbalch equation- Henderson-Hasselbalch Equation to determine the pH of a solution. Knowing the pH of a solution is particularly significant for many chemical processes as well as for biological systems. The estimated pH value of a buffer solution may be determined using the Henderson-Hasselbalch equation.

pH- A solution's acidity or alkalinity may be determined based on the concentration of hydrogen ions in the solution, or pH. Typically, the pH scale runs from 0 to 14.

Is a cells main function is to produce proteins to be excreted, such as on the pancreas, which organelles would you expect to be
nevsk [136]
Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.

goblinko [34]

Answer:

All of the above.

Explanation:

Jealousy is the emotional state of feeling jealous. This is more of a negative aspect rather than a positive one, but can also sometimes be a positive aspect in a relationship.

Jealousy incites the person to have negative feelings like anxiousness, wrath, anger, possessiveness, excitement, etc. But it can also lead to an increase in the passionate feelings for the other person, which can make the individual pay more attention to the other person. In this aspect, it becomes a positive thing.

Thus, the correct answer is all of the above.
