They synthesizes proteins

WebThe raw proteins synthesized from ribosomes are purely long chains of amino acids. These proteins need to be modified by adding carbohydrate (sugar units) portions to become “glycoproteins”. The prefix “glycol-” means “sugar”. [In this figure] Type of glycoprotein. Photo credit: BioProcess. WebIn eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the …

Most of the time, the amino acids are recycled into the synthesis of new proteins. If there are excess amino acids, however, or if the body is in a state of starvation, some amino acids will be shunted into the pathways of glucose catabolism (Figure 7.6. 1 ). b\u0026o play https://cosmicskate.com
