Introduction on Rough and Smooth Endoplasmic Reticulum
Rough and smooth endoplasmic reticulum are two types of organelles found in the cytoplasm of eukaryotic cells. Rough endoplasmic reticulum has a roughened appearance due to the presence of ribosomes on its surface, while smooth endoplasmic reticulum lacks ribosomes.
The primary function of the endoplasmic reticulum is to synthesize proteins. The rough endoplasmic reticulum is responsible for synthesizing proteins that will be exported from the cell, while the smooth endoplasmic reticulum synthesizes proteins that will be used within the cell.
What is an endoplasmic reticulum?
The endoplasmic reticulum (ER) is a membranous network of tubes and sacs that forms a continuous internal surface in the cytoplasm of eukaryotic cells. The ER is involved in a variety of biochemical activities, including the synthesis of proteins, the transport of proteins and lipids, and the storage of calcium ions. The ER also plays a critical role in the folding of proteins into their correct three-dimensional shapes.
Types of ERP
ERP systems can be classified into three types:
1. On-premises ERP systems: These are installed on the customer’s premises. They are custom-made to meet the customer’s specific requirements.
2. Hosted ERP systems: These are hosted by the software vendor on their servers. Customers access these systems over the internet.
3. Cloud-based ERP systems: These are hosted by a third party on their servers. Customers access these systems over the internet.
Functions of Rough Endoplasmic Reticulum
The rough endoplasmic reticulum (RER) is a type of organelle found in the cytoplasm of eukaryotic cells. It is a network of interconnected tubules and sacs that performs several important functions, including protein synthesis and transport, lipid synthesis and transport, and calcium ion storage.
Smooth Endoplasmic Reticulum
The smooth endoplasmic reticulum (SER) is a membranous network of interconnected tubes and sacs that forms a continuous system throughout the cytoplasm of eukaryotic cells. The primary function of the smooth endoplasmic reticulum is to modify and package proteins for secretion from the cell. The SER also helps to maintain the cell’s fluidity by pumping calcium ions in and out of the cell.
Functions of SERMs
SERMs are a class of drugs that act as estrogen receptor modulators. This means that they can mimic the effects of estrogen in some tissues, while blocking its effects in others. This gives them a variety of potential therapeutic applications, including the treatment of breast cancer, osteoporosis, and menopausal symptoms.
Overall functions of endoplasmic reticulum
The endoplasmic reticulum (ER) is a membranous network of tubes and sacs that occupies most of the cell cytoplasm. It is a site of protein synthesis and folding and is also involved in the transport of materials within the cell. The ER has two main functions: (1) to synthesize proteins and (2) to transport materials.
Difference between RER and SER
RER stands for “regional express railway” and SER stands for “Spanish railway network”. The main difference between the two is that RER is specific to France, while SER is specific to Spain. SER also has a much larger network than RER.
There is a significant difference between RER and SER. RER stands for “relative effective resistance.” It is a measure of the resistance offered by a particular circuit to the flow of alternating current. SER stands for “series equivalent resistance.” It is a measure of the resistance offered by a particular circuit to the flow of direct current.
