In addition to synthesizing lipids, the smooth endoplasmic reticulum plays an important role in detoxification of chemicals. This detoxification process occurs in the liver, which contains an abundance of smooth endoplasmic reticulum.
What cell detoxifies alcohol?
Some types of peroxisomes, such as those in liver cells, detoxify alcohol and other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (a process termed oxidation).
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.
What organelle cleans and detoxify cells?
Lysosomes are the cleanup crew of a cell. Lysosomes are small, enzyme filled organelles. They digest (breakdown) lipids, carbohydrates, and proteins that the rest of the cell can use.
Do ribosomes detoxify?
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 alcohol convert to in the body?
ADH breaks down alcohol into acetaldehyde, and then another enzyme, aldehyde dehydrogenase (ALDH), rapidly breaks down acetaldehyde into acetate. The acetate is further metabolised, and eventually leaves your body as carbon dioxide and water.
How is most alcohol removed from the body?
Metabolism of alcohol
More than 90% of alcohol is eliminated by the liver; 2-5% is excreted unchanged in urine, sweat, or breath.
Which organelle is responsible for making proteins?
Ribosomes. Ribosomes are the protein factories of the cell.
What is powerhouse of cell?
EXPLORE. Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
What is the main function of ribosome?
Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
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 organelle is responsible for energy?
Chloroplasts and mitochondria are energy-converting organelles in the cytoplasm of eukaryotic cells. Chloroplasts in plant cells perform photosynthesis; the capture and conversion of the energy of sunlight.
What type of cell is 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.
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 produces ribosomes in the cell?
Eukaryote ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).
What organelle breaks down lipids and toxins?
-Endoplasmic Reticulum (ER)-organelle that makes lipids, breaks down drugs and other substances, and packages proteins for the golgi complex.
