C. Deoarece ele cresc și se dezvoltă, asta înseamnă c:)
Answer:
C. They are carried by motor proteins using the cytoskeleton as a "roadway"
Explanation:
Vesicles hitch a ride on molecular motors such as kinesin or myosin, moving along the cytoskeleton until they reach their intended location, where they then fuse with the target membrane or organelle. Typically, vesicles progress from the ER to the cis Golgi, followed by movement from the cis to the medial Golgi, from the medial to the trans Golgi, and finally from the trans Golgi to the plasma membrane or other cellular compartments. While the predominant direction is forward, there are also vesicles that return from the Golgi to the ER, carrying proteins that should have remained in the ER (e.g., PDI) that were inadvertently enclosed in a vesicle.
To enhance students' retention of information regarding the cell, it is advisable for the teacher to assist them in encoding this information in both visual and verbal formats. Implementing various encoding techniques can significantly boost the chances of easier retrieval. In this scenario, encoding refers to transforming the names of the cell organelles into easily memorable forms.
mRNA functions as the messenger that conveys DNA's instructions to ribosomes, which are responsible for protein synthesis. Meanwhile, tRNA aids in transporting the requisite amino acids to the ribosomes. Essentially, mRNA specifies the amino acids required and their sequence, while tRNA collects these amino acids and delivers them to the ribosomes.
