What type of cells have smooth endoplasmic reticulum?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What types of cells in a human body contain large amounts of rough ER?
Although all nucleated mammalian cells have at least some rough ER, cells that produce large quantities of secretory proteins—such as the exocrine cells of the pancreas, which function as factories for digestive enzymes (seepp. 879–881)—are endowed with an abundance of rough ER.
Which of the following organelles would you expect to be particularly abundant in a cell that secreted high amounts of lipid based hormones?
Smooth ER is particularly abundant in cells that synthesize lipids (e.g., fatty acids, phospholipids, cholesterol, and steroid hormones).
Is the smooth ER in plant and animal cells?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
Do plant cells have endoplasmic reticulum?
Plant and animal cells also have many common organelles, including the nucleus, cell membrane (called the plasma membrane in animals) endoplasmic reticulum, mitochondria and cytoplasm, as well as several others.
What type of cells have smooth ER?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What cells contain rough endoplasmic reticulum?
RER occurs in both animal and plant cells. The RER membrane is continuous with the nuclear envelope, which surrounds the cell nucleus. The RER is also located near the Golgi apparatus, which transports, modifies, and packages proteins for delivery to targeted destinations.
Which organelle is most prominent in cells that make large amounts of protein?
The organelle that is most prominent in cells that make large amounts of protein is the ribosome.
What type of organelle would be found in high amounts in a liver cell?
The smooth endoplasmic reticulum also contains enzymes responsible for degrading inorganic toxins, such as alcohol and drugs. This organelle is especially prevalent in hepatocytes (liver cells) where the blood if filtered and toxins are removed for degradation.
What is smooth ER in plant cell?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
Which of the following has extensive smooth ER?
Liver cells have an impressive network of smooth endoplasmic reticulum. Similarly, cells of the ovaries and testes, which produce the lipid-containing hormones estrogen and testosterone, contain large amounts of smooth endoplasmic reticulum.
What is smooth endoplasmic reticulum in plant cell?
Definition of the Smooth ER The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What is endoplasmic reticulum in animal cell?
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.
Which organelle is most prominent in cells that make large amounts of protein quizlet?
Chromosomes consist of ________ and ________. Which organelle is most prominent in cells that make large amounts of protein? nucleoli.
Why do liver cells have more smooth ER?
Large amounts of smooth ER are found in liver cells where one of its main functions is to detoxify products of natural metabolism and to endeavour to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
What does a smooth ER do in a plant cell?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What cell is the rough endoplasmic reticulum found in?
eukaryotic cells rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
Which organelle is more prominent in cells that make large amounts of protein?
The organelle that is most prominent in cells that make large amounts of protein is the ribosome.
Which of the following is a function of the smooth endoplasmic reticulum ER )? Quizlet?
Which of the following is a function of the smooth endoplasmic reticulum? lipid manufacture. (The smooth ER serves as a workspace for enzymes. Depending on the cell type, these enzymes may make lipids, detoxify poisons, or break down glycogen chains.)
What types of cells have lots of smooth endoplasmic reticulum?
Large amounts of smooth endoplasmic reticulum are found in cells that specialize in lipid metabolism. For instance, liver cells remove alcohol and drugs from the bloodstream. Liver cells have an impressive network of smooth endoplasmic reticulum.
What cells produce large amounts of proteins?
Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.
Which organelle is more prominent in cells that make large amounts of protein quizlet?
Chromosomes consist of ________ and ________. Which organelle is most prominent in cells that make large amounts of protein? nucleoli.
What specialized smooth ER is found in muscle cells?
sarcoplasmic reticulum In muscle cells, a distinct type of smooth endoplasmic reticulum is present which is referred to as sarcoplasmic reticulum. The sarcoplasmic reticulum or SR is a highly specialized form of the smooth endoplasmic reticulum which regulates intracellular calcium homeostasis.
What is smooth endoplasmic reticulum 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 does smooth ER do in a plant cell?
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.
