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 cell structure detoxifies alcohol?
Peroxisomes in liver cells help to detoxify alcohol and other harmful substances through oxidation.
Does smooth ER detoxify alcohol?
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.
Which organelle is responsible for detoxification?
The smooth endoplasmic reticulum is also responsible for detoxifying the cell. It is more tubular than the rough endoplasmic reticulum, and is not necessarily continuous with the nuclear envelope.
Does the SER detoxify alcohol?
It also possesses some tissue-specific functions: in the liver, the SER contains large amounts of cytochrome P450 and participates in the detoxification of metabolic waste products, drugs, and alcohol; in the muscle, the SER is known as the sarcoplasmic reticulum and stores and releases calcium ions needed for muscle …
What is Cytoplasms?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
What type of cell is a ribosome?
Ribosomes are found in prokaryotic and eukaryotic cells; in mitochondria, chloroplasts and bacteria. Those found in prokaryotes are generally smaller than those in eukaryotes. Ribosomes in mitochondria and chloroplasts are similar in size to those in bacteria.
Why do alcoholics have more smooth ER?
Alcoholics have a lot more Smooth ER than people who don’t drink. As people consume more alcohol, they realize that they have to continue to drink more to get the same effect. This happens because more inactivating enzymes are being produced. These inactivating enzymes are responsible for helping to detoxify the liver.
How do liver cells detoxify poisonous substances?
The liver filters toxins through the sinusoid channels, which are lined with immune cells called Kupffer cells. These engulf the toxin, digest it and excrete it. This process is called phagocytosis. As most chemicals are relatively new it will be thousands of years before our body properly adapts to them.
What is detoxified in the smooth ER?
One of the most important and main functions of Smooth Endoplasmic Reticulum is detoxification, which is the removal of all the toxic materials such as (metabolic wastes or drugs).
What is the main function of mitochondrion?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Which organelle is responsible for making proteins?
Ribosomes. Ribosomes are the protein factories of the cell.
Where do lysosomes arise?
Lysosomes which arises from the Golgi apparatus. Together with the Golgi apparatus, the endoplasmic reticulum is called the cell’s protein machinery.
What cells have lots of Ser?
Specialized cells can have a lot of smooth endoplasmic reticulum and in these cells the smooth ER has many functions. It synthesizes lipids, phospholipids, and steroids. Cells which secrete these products, such as those in the testes, ovaries, and sebaceous glands have an abundance of smooth endoplasmic reticulum.
Where do humans have a lot of Ser?
This comes in two types, “smooth” and “rough.” The cells of the liver, ovaries and testes have a high density of smooth endoplasmic reticulum (smooth ER, or simply SER), whereas organs that secrete a great deal of protein, such as the pancreas, have cells rich in rough endoplasmic reticulum (rough ER, or simply RER).
What does a ser do?
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 …
