What can endoplasmic reticulum be compared to?
What can endoplasmic reticulum be compared to?
The endoplasmic reticulum is like the highway system because the cell uses the endoplasmic reticulum to move material throughout the cell like people use highways to move throughout the country.
What is the endoplasmic reticulum like in a city?
The endoplasmic reticulum consists of a network of a tube-like passageway through which proteins from the ribosomes are able to be moved within a cell as the road system allows for movement throughout the city. The ribosomes are small grain-like bodies made mostly of RNA and produced in the nucleolus.
What is a good analogy for smooth endoplasmic reticulum?
Smooth Endoplasmic Reticulum = Manufacturing Plant: They both make proteins and fats. They are then packaged and sent off. 9. Golgi Apparatus = Post Office: They are sorted, then packaged and distributed around the cell, just like a post office would do with mail.
What is the analogy of rough ER?
An analogy for the rough endoplasmic reticulum is that the rough endoplasmic reticulum is like a factory.
What is the role of the rough ER?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
How are rough and smooth ER similar?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
What does the RER do in a cell?
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.
Why is the endoplasmic reticulum important?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. Proteins synthesized by the RER have specific final destinations, such as the cell membrane, cell exterior, or the ER itself.
What diseases does the endoplasmic reticulum cause?
There is accumulating evidence implicating prolonged ER stress in the development and progression of many diseases, including neurodegeneration, atherosclerosis, type 2 diabetes, liver disease, and cancer.
Which cells have lots of smooth ER?
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 would happen if the smooth endoplasmic reticulum stopped working?
The smooth ER has an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well. Without ER in the skeletal muscle fibers couldn’t happen muscle contraction. In the absence of these cellular mechanisms the cell would probably die.
What is more abundant in smooth endoplasmic reticulum?
So, the correct option is ‘Tubules and vesicles’.
Which is more abundant in ser?
So, the correct answer is ‘Tubules and vesicles’.
What is more abundant in the cell?
water
What cell is made up of?
All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.
What is the second most abundant substance in the human body?
carbon
Which molecule is most common in the human body?
Water
What element is the human body made of?
The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
