Explanation:

The smooth absorbent reticulum has actually a variety of functions. Proteins deserve to be packaged and transported with the cell by the smooth absorbent reticulum, as have the right to other moving components and also materials. The membrane roughly the smooth endoplasmic reticulum deserve to be provided to create intracellular vesicles. The smooth endoplasmic reticulum is likewise responsible for using these vesicles to interface with the plasma membrane, manufacturing phospholipids come repair and grow the membrane surface ar area. The smooth endoplasmic reticulum likewise contains enzymes responsible because that degrading inorganic toxins, such together alcohol and also drugs. This organelle is specifically prevalent in hepatocytes (liver cells) where the blood if filtered and toxins are gotten rid of for degradation.

You are watching: In a liver cell detoxifying alcohol

Protein synthesis requires the activity of ribosomes, which deserve to be uncovered in the cytosol or embedded in the membrane that the rough endoplasmic reticulum.

Example concern #2 : understanding The absorbent Reticulum and also Golgi body


A researcher observes 2 organelles under the microscope. He notices that organelle A contains more amino acids 보다 organelle B. What might the researcher conclude about the 2 organelles?


Possible Answers:

Organelle A is smooth endoplasmic reticulum and it consists of ribosomes


Organelle B is rough endoplasmic reticulum and also it has ribosomes


Organelle A is rough endoplasmic reticulum and also it consists of ribosomes


Organelle B is smooth endoplasmic reticulum and it has ribosomes


Correct answer:

Organelle A is unstable endoplasmic reticulum and it includes ribosomes


Explanation:

The concern states the organelle A has an ext amino acids. This way that organelle A has much more proteins than organelle B. Psychic that rough endoplasmic illusion (rough ER) is termed ‘rough’ because it consists of ribosomes top top its surface. These ribosomes provide it a turbulent appearance under the microscope. Ribosomes room the site of protein synthesis, therefore, rough ER will contain an ext proteins (and amino acids).

We can not draw any conclusions around organelle B, because most oribel contain fewer amino acids and proteins than the unstable endoplasmic reticulum.

Which organelle is most essential for a person who has actually consumed too much alcohol?


Possible Answers:

Ribosomes


Mitochondria


Rough absorbent reticulum


Smooth absorbent reticulum


Correct answer:

Smooth absorbent reticulum


Explanation:

The concern states the the person has consumed too much alcohol, which way that the body need to detoxify the chemicals from alcohol. You are as such looking because that the organelle the participates in detoxification the chemicals. In enhancement to manufacturing lipids, the smooth endoplasmic reticulum plays vital role in detoxification of chemicals. This detoxification process occurs in the liver, i m sorry contains an abundance of smooth absorbent reticulum.

Rough endoplasmic reticulum and ribosomes are involved in protein synthesis, and mitochondria space the site of energy (ATP) production.

Example question #4 : expertise The endoplasmic Reticulum and also Golgi human body


Steroids are an important component of cabinet membranes and gonadal hormones. What organelle is most crucial in the synthesis of steroids?


Possible Answers:

Smooth absorbent reticulum


Rough absorbent reticulum


Golgi apparatus


Lysosomes


Correct answer:

Smooth endoplasmic reticulum


Explanation:

Steroids space a form of lipid that encompass cholesterol (needed because that cell membranes) and gonadal hormones (estrogen, testosterone, and also progesterone). Due to the fact that they are lipids, steroids space synthesized in the smooth absorbent reticulum, the site of lipid synthesis.

Remember that smooth absorbent reticulum likewise plays a function in detoxification of harmful chemicals.

Rough absorbent reticulum is used to develop proteins that will be secreted from the cell, including most peptide hormones. The Golgi apparatus is offered to modify these proteins and also create vesicles because that protein transport. Lysosomes contain hydrolytic enzymes the digest cellular wastes.

Bob, a biologist who was researching a brand-new eukaryotic uncellular cells species, wanted to study a certain protein Y. After ~ obtaining and also purifying the sample, Bob uncovered that this protein had 3 subunits: A, B, and C. Through substantive scientific analysis, Bob discovered that protein Y activate in a membrane; however, he could not deduce which certain membrane. Nonetheless, Bob found that just subunit B to be traversed v the interior of the membrane. With Bob’s findings, you re welcome answer the following questions.


Where is this protein synthesized? 


Possible Answers:

Cytoplasm


Rough absorbent reticulum


Golgi apparatus


Nucleolus


Smooth absorbent reticulum


Correct answer:

Rough endoplasmic reticulum


Explanation:

The only feasible answer choices are the rough ER and also Cytoplasm because proteins room synthesized in these 2 components. Protein intended to it is in membranous space synthesized exclusively on the stormy ER.

Example inquiry #6 : expertise The absorbent Reticulum and Golgi human body


Which that the complying with organelles is responsible for detoxification?


Possible Answers:

Ribosome


Mitochondria


Rough endoplasmic reticulum


Golgi apparatus 


Smooth endoplasmic reticulum


Correct answer:

Smooth absorbent reticulum


Explanation:

Smooth absorbent reticulum(ER) is responsible for the detoxification the a variety of organic chemicals. The smooth ER converts necessary substances right into water and other soluble products to permit for excretion. Huge amounts that smooth ER are discovered in liver cells, where assets of herbal metabolism, drugs, and also alcohol are detoxified. Fun fact: the smooth ER can twin its surface ar area within a couple of days then go back to its typical size as soon as the attack has subsided.

Example concern #7 : understanding The absorbent Reticulum and Golgi body


Lipid synthesis occurs in which of the adhering to cell organelles?


Possible Answers:

Golgi apparatus


Rough endoplasmic reticulum


Smooth endoplasmic reticulum


Vacuole


Lysosome 


Correct answer:

Smooth endoplasmic reticulum


Explanation:

Smooth endoplasmic reticulum (ER) is dedicated almost specifically to the to produce of lipids, and also in some situations the line of lipids and their linked products. Smooth ER synthesizes lipids, phospholipids, and also steroids. It also carries out the management of carbohydrates and drug detoxification. The smooth ER the the endoplasmic reticulum lacks ribosomes, hence the name smooth ER.

Example inquiry #8 : expertise The absorbent Reticulum and also Golgi human body


What is the main role of the Golgi apparatus?


Possible Answers:

Produce DNA


Produce proteins


Sorts and also ships protein to the exactly place


Produce enzymes


Correct answer:

Sorts and also ships proteins to the correct place


Explanation:

The Golgi device (body) sorts and also ships proteins to the correct place. That does not develop proteins or enzymes, a kind of protein. Rough ER and ribosomes produce proteins. The Golgi apparatus does not develop DNA, i m sorry is the genetic code produced in the process of replication, and occurs in the cell core of eukaryotic cells.

Example concern #9 : expertise The endoplasmic Reticulum and Golgi body


What is the duty of unstable endoplasmic reticulum (ER)?


Possible Answers:

Synthesis that lipids


Conversion of DNA to RNA


Synthesis of proteins


Production that DNA


Correct answer:

Synthesis of proteins


Explanation:

Rough absorbent reticulum (ER) is involved in the synthesis of proteins. Smooth endoplasmic reticulum is connected in the synthesis of lipids. The switch of DNA to RNA is called transcription however does not involve stormy ER. Production of DNA is replication and also occurs in the nucleus, as does transcription.

Example question #10 : knowledge The absorbent Reticulum and also Golgi human body


The smooth absorbent reticulum\"s main function is __________.


Possible Answers:

regulate water intake


synthesize RNA


synthesize lipids and also detoxify harmful substances


synthesize proteins


Correct answer:

synthesize lipids and detoxify harmful substances


Explanation:

Smooth absorbent reticulum (ER) synthesizes lipids and also detoxifies harmful substances. RNA synthesis wake up in transcription but does no involve Smooth ER. Proteins are synthesized by unstable ER and also ribosomes. Water input is regulated by vacuoles, i beg your pardon are current in a couple of animal cell types.
