Explain why stomach cells have a large quantity of ribosomes and golgi apparatus ?
Stomach cells, also known as gastric cells, have a large quantity of ribosomes and Golgi apparatus because these organelles play crucial roles in protein synthesis and secretion, which are essential for the function of stomach cells.
Ribosomes are responsible for protein synthesis. They are tiny structures made up of RNA and protein. When a cell needs to produce proteins, ribosomes read the instructions encoded in the messenger RNA (mRNA) and assemble amino acids into a chain, forming a protein. Stomach cells require a significant amount of protein synthesis because they produce digestive enzymes, which are proteins necessary for breaking down food molecules.
The Golgi apparatus, often called the Golgi complex or Golgi body, is responsible for modifying, packaging, and transporting proteins within the cell. It consists of a stack of membrane-bound sacs called cisternae. After proteins are synthesized by the ribosomes, they pass through the Golgi apparatus. Here, the proteins undergo post-translational modifications, such as folding into their final conformation, adding sugar molecules (glycosylation), or attaching lipids. These modifications are crucial for ensuring the proteins' proper function. The Golgi apparatus also packages the modified proteins into vesicles for transport to other parts of the cell or for secretion outside the cell. Stomach cells need a well-developed Golgi apparatus to properly process and package the digestive enzymes they produce.
To understand why stomach cells have a large quantity of ribosomes and Golgi apparatus, you can look into histological studies or research articles that investigate the ultrastructure and function of gastric cells. These studies often involve techniques like electron microscopy, immunostaining, or molecular biology methods. By examining these resources, you can gain a deeper understanding of the cellular components and processes that contribute to the specific characteristics of stomach cells.
