They make proteins that perform all sorts of functions for the cell 39 s operation. 8 g kg per day recommend intake. In humans the nucleus of each cell contains 3 10 9 base pairs of DNA distributed over 23 pairs of chromosomes and each cell has two copies of the genetic material. Muscle protein synthesis rate is reported to be reduced 30 in the elderly but there is controversy as to the extent to which this reduction is due to nutrition disease or physical inactivity rather than aging. For translation and protein synthesis to take place many initiator and release chemicals are involved and many reactions using enzymes take place. One of the essential cell organelles are ribosomes which are in charge of protein synthesis. Protein synthesis in the cell is conducted by ribosomes that are found attached to the membrane of endoplasmic reticulum and microsomes as well as in free state in the groundplasm. These small subunits are then put together in the ribosomes that are attached to the membrane of the rough endoplasmic reticulum. mitochondria contains a circular double stranded DNA in it commonly called mitochondrial DNA. m RNA is synthesized in the presence of the enzyme KNA polymerase.

A larger and more Animals store carbohydrates as ______. There water H 2 O is oxidized and oxygen O 2 is released. The rate of protein synthesis is higher in prokaryotes than eukaryotes and can reach up to 20 amino acids per second. Another unique aspect of mitochondrial DNA is that you inherit it only from your mother the mitochondria that exist in the egg cell . They are formed in the nucleolus which is found inside the nucleus. B glycogen Where does protein synthesis take place A in the nucleolus The RNAs migrate from the nucleus into the cytoplasm. Once the mRNA has been synthesized and perhaps modified the next step of protein synthesis translation takes place. Protein synthesis is powered by ATP. For example genes rarely operate during mitosis. This process is called as transcription. 19 Diagram showing the basic structures of the animal cell nucleus. where does protein synthesis take place in an animal cell
