What is the short definition of endoplasmic reticulum?
A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough. The endoplasmic reticulum is a cell organelle.
What is the main function of the smooth endoplasmic reticulum quizlet?
One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids, an essential component of a cell’s outer membrane, and steroids.
What is the function of smooth ER and smooth ER?
Definition of the Smooth ER The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism. The smooth ER also regulates and releases calcium ions and processes toxins.
What are the two main functions of the smooth endoplasmic reticulum?
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
What is smooth endoplasmic reticulum in animal cell?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
What are the two primary functions of the smooth ER?
What is the smooth ER quizlet?
smooth endoplasmic reticulum. collection of enzymes that perform specialized tasks, including synthesis of membrane lipids and the detoxification of drugs. endoplasmic reticulum. site where lipid components of the cell membrane are assembled, along with proteins and tother materials that are exported from the cell.
What happens when the smooth endoplasmic reticulum malfunctions?
A malfunction of the ER stress response caused by aging, genetic mutations, or environmental factors can result in various diseases such as diabetes, inflammation, and neurodegenerative disorders including Alzheimer’s disease, Parkinson’s disease, and bipolar disorder, which are collectively known as ‘conformational …
