Cacao beans arrive in a factory from the areas where they grew. At the factory, the best beans are sorted and put into bags. Aft
er quality-control workers check the bags, a large truck transports the cacao beans to a commercial chocolate-producing company. Which organelle plays a similar role inside a cell?
The question lacks options, the options are: a. cytoplasm b. golgi body c. mitochondrion d. ribosome e. vacuole
The answer is Golg body/apparatus
Explanation:
Proteins are synthesized in the ribosomes after a gene has successfully undergone transcription and translation processes. However, the synthesized protein needs to undergo sorting, modification and packaging before it finally leaves for its final destination. These process of sorting, modification and packaging is conducted by an organnelle called GOLGI APPARATUS. The modified protein is then transported via transport vesicles to their respective target locations or organs where they will be used.
The illustration in the question here is similar to the above explanation. Cacao beans are the proteins produces from gene expression. They arrive in the factory, which is the Golgi apparatus in this case and undergo sorting and packaging. After this processes, they are later put into large trucks, which are the transport vesicles, and transported to a commercial chocolate company (target location/organs) which they are used.
The arrival of cacao beans in the factory can be likened to the transcription of mRNA using a DNA template.
Sorting of the best beans at the factory can be likened to splicing process. During splicing, the introns are removed from the newly synthesized mRNA and the exons are joined together. The introns represent the non-coding portion of the mRNA while the exons represent the coding sequence.
The checking of bags by quality control can be likened to the final proofreading of the mRNA after splicing before being transported to the cytoplasm where they are used to synthesize proteins.
The large truck that transports the cacao beans represent the transport proteins that transport the mRNA to the cytoplasm while the chocolate-producing company represents the ribosome which is the site of protein synthesis.
Lipids are good for making the cell membrane because they are stronger and block out things that should not be getting in out, for instance lipids mainly only let water and gases pass through.
