It is sub-classified as a rough, or granular ER, and a smooth or agranular ER. The rough Endoplasmic reticulum is lined with ribosomes and modifies and packages proteins that have been produced by the ribosome. In skeletal and cardiac muscle it is known as the sarcoplasmic reticulum.
Answer:
The correct answer is ''the mechanisms for coordinating subunits.''
Explanation:
Integration mechanisms are explicitly defined to coordinate subunits. In turn, are divided into structural and non-structural mechanisms. Structural integration mechanisms coordinate activities and are usually linked to specific management positions or bodies. The non-structural integration mechanisms, for their part, are characterized because they do not create organs or positions, but they constitute a relevant complement to the structural mechanisms, facilitating the organization of work. Informal integration mechanisms or those aimed at facilitating informal relationships are the simplest and easiest to use. Individuals face a certain situation and, spontaneously, communicate with each other. If no further coordination is required, informal mechanisms may be sufficient
Answer:
sorry I don't know the answers
The proteins exhibit four levels of organization:
1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.
2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.
3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.
4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.
Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.
