What is the function of the endoplasmic reticulum?
What is the function of the endoplasmic reticulum?
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.
What are the 3 main functions of the endoplasmic reticulum?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.
What is the nucleolus function?
The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.
What is a cellular nucleus?
The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. A double-layered membrane, the nuclear envelope, separates the contents of the nucleus from the cellular cytoplasm.
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.
What will happen if the endoplasmic reticulum stopped working?
The rough ER has attached ribosomes critical for protein synthesis. Smooth ER produce lipids and steroids etc so basically cells NEED these organelles. Without them many enzymatic processes would be unable to occur ultimately killing the cell.
What is endoplasmic reticulum in simple words?
Endoplasmic reticulum (ER) is a cellular organelle. It is the transport network for molecules going to specific places, as compared to molecules that float freely in the cytoplasm. The endoplasmic reticulum is in cells that have a nucleus: in eukaryote cells but not in prokaryote cells.
What’s the difference between nucleus and nucleolus?
The nucleus is the main part of the cell while the nucleolus is part of the nucleus itself. The nucleus is a membrane-bound organelle that is found in multi-celled organisms or eukaryotes. This membrane that encloses the nucleus has two parts. On the other hand, the nucleolus is a non-membrane enclosed organelle.
What are 3 functions of the nucleus?
What is the nucleus?
- The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells.
- The primary functions of the nucleus are to store the cell’s DNA, maintain its integrity, and facilitate its transcription and replication.
What is a cell?
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface.
What happens if endoplasmic reticulum malfunction?
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 …
