1. digestive and circulatory
The digestive system and the circulatory system are most directly involved in providing human cells with the molecules needed for the synthesis of fats. The digestive system breaks down food into nutrients that are absorbed into the bloodstream, which is then circulated to cells for cellular processes, including the synthesis of fats.
Mitochondria are not directly involved in synthesis. They are responsible for producing energy in the form of ATP through cellular respiration, but they do not synthesize molecules like proteins or nucleic acids.
Ribosome
protein synthesis
Ribosomes involve in protein synthesis. They involve in the synthesis by providing surface.
protein synthesis
Protein synthesis primarily occurs in the ribosomes, which are located in the cytoplasm of the cell. The nuclear envelope surrounds the nucleus and is involved in regulating the passage of molecules in and out of the nucleus, but it is not directly involved in protein synthesis.
mRNA molecules are involved in transcription but not translation. mRNA carries the genetic information from DNA to the ribosome for protein synthesis during translation.
RNA molecules have many functions, but in the majority of cells most RNA molecules are involved in just one job- protein synthesis.
The three key molecules involved in synthesis are amino acids, nucleotides, and monosaccharides. Amino acids are the building blocks of proteins, nucleotides are the monomers of nucleic acids (like DNA and RNA), and monosaccharides are the simplest carbohydrates that can combine to form polysaccharides. Together, these molecules play crucial roles in the biological synthesis of macromolecules, which are essential for cellular structure and function.
RNA molecules are most involved in protein synthesis, specifically in the process of translation where messenger RNA (mRNA) is decoded by ribosomes to produce proteins. RNA molecules such as transfer RNA (tRNA) and ribosomal RNA (rRNA) play key roles in this process by carrying amino acids and forming the ribosome structure, respectively.
During synthesis, the molecules are produced by the ribosomes and then modified in the endoplasmic reticulum and Golgi apparatus. The molecules are then packaged into vesicles in the Golgi apparatus and transported to the cell membrane for secretion.
