The ribosomes are the most likely target of streptomycin in prokaryotes. Streptomycin interferes with the function of the bacterial ribosome, specifically the 30S subunit, disrupting protein synthesis and leading to cell death.
Most likely not. Yet, there are examples of non-ribosome mediated protein synthesis in some bacteria, e.g. the synthesis of cyclosporin by the Cyclosporin synthethase complex. But this is a very rare phenomenon, and besides these non-ribosomal peptide synthetases are ofcourse themselves synthesized by the ribosome.
A cell that contains ribosomes and cytoplasm is likely a eukaryotic cell, such as an animal or plant cell. Ribosomes are responsible for protein synthesis, and cytoplasm is the gel-like substance that fills the cell and houses the organelles.
If a cell synthesizes large quantities of protein molecules, it would likely have numerous ribosomes and an extensive rough endoplasmic reticulum (RER). Ribosomes are the sites of protein synthesis, while the rough ER is involved in the folding and processing of newly synthesized proteins. Additionally, the Golgi apparatus may also be abundant to facilitate the modification and packaging of these proteins for secretion or delivery to other organelles.
A more active cell is likely to have more mitochondria to support energy production through aerobic respiration. It may also have a higher concentration of ribosomes for protein synthesis and endoplasmic reticulum for protein folding and processing. Additionally, an active cell may have an increased number of lysosomes for cellular waste processing and recycling.
It wouldn't be protein synthesis.

If ribosomes in a cell were damaged and stopped functioning, protein synthesis would be disrupted. This could lead to a decrease in cell function, impaired growth and development, and ultimately cell death.
A cell that contains ribosomes and cytoplasm is likely a eukaryotic cell, such as an animal or plant cell. Ribosomes are responsible for protein synthesis, and cytoplasm is the gel-like substance that fills the cell and houses the organelles.
If ribosomes in a cell stopped working, protein synthesis would cease, leading to a lack of essential proteins needed for cell function. This would ultimately result in cell death and potentially disrupt overall cell function in the organism.
The largest number of bound ribosomes would likely be found in cells that are actively synthesizing proteins, such as cells that secrete a large amount of proteins or hormones. These cells would have a high demand for protein production, which requires a significant number of ribosomes attached to the endoplasmic reticulum for protein synthesis.
A pancreatic cell is highly active in protein synthesis, so it would likely have a large number of ribosomes compared to other cell types. Ribosomes are present in both the cytoplasm and attached to the endoplasmic reticulum in a cell.
Since enzymes are made by ribosomes, it can either have an abundance of ribosome, or an abundance of rough endoplasmic reticulum.
the synthesis of enzymes would stop
A cell with a large amount of rough endoplasmic reticulum (ER) is likely involved in protein synthesis and secretion. The rough ER is studded with ribosomes that are responsible for translating mRNA into proteins. These proteins are typically destined for secretion or insertion into the cell membrane.
protein, as proteins are the most abundant macromolecules synthesized in cells and play a variety of essential roles in cell structure and function. Proteins are synthesized through a process called protein synthesis, which involves transcription of DNA to mRNA and translation of mRNA to protein at ribosomes.
