Ribosomes
Ribosomes assemble amino acids into proteins.
Ribosomes
Ribosomes are small structures within cells that serve as the workbench for the manufacture of proteins. They are composed of RNA and proteins, and function by reading the genetic information from mRNA to assemble amino acids into specific sequences, resulting in the production of proteins.
Adjacent cells at a gap junction are connected by proteins called connexins. These proteins assemble to form connexons, which are hexameric structures that create channels between cells. These channels allow for the direct transfer of ions and small molecules, facilitating intercellular communication and coordination of cellular activities.
The right question would be, "Do cells make proteins FROM small structures called amino acids?" The short answer is, yes. If your interested in how look up the Hierarchy of Protein Structures. Specifically: Primary Structure ie. the amino acid sequence Secondary Structure ie repeating folding patterns (which help determine function.) Tertiary Structure ie. many folds and patters create a 3-D shape. For some proteins this is the final structure to a functional protein (such as ribonuclease). Quaternary Structure ie. Most functional proteins are comprised of two or more polypeptides that each adopt a Tertiary Structure (see above) and then assemble with each other. When proteins consist of more than one polypeptide chain, they are said to have Quarternary Structure.
A ribosome is the organelle that builds proteins. Is that what you are looking for? If not, sorry! :(
Ribosomes have a small granular structure and are responsible for protein synthesis in cells. They are made of RNA and proteins and can be found in the cytoplasm or attached to the endoplasmic reticulum.
organelles
No, small structures in the cytoplasm such as ribosomes are not considered organelles. Organelles are membrane-bound compartments with specific functions, while ribosomes are non-membrane bound structures involved in protein synthesis.
