... the cell the ability to move and ensure proper cell division during cellular reproduction. 5. Microfilaments are two-stranded (double helix) helical polymers of the protein actin. They appear as flexible structures with a diameter of 5 - 9 nm and are organized into a variety of linear bundles, two-dimensional networks, and three-dimensional gels. Microtubules are long, hollow cylinders made of ... the nucleus that creates ribosomes. 10. Polysomes play a major role in protein synthesis, which is the process in which amino acids are linearly arranged into proteins according to DNA sequen...

... workouts, protein is essential to rebuild worn out tissue, and rebuild muscle. Proteins are polymers and work by being broken down into smaller components named amino acids, and then rebuild again where and when they are needed. These amino acids join together as chains which can be twisted and folded depending on the molecular structure. There are twenty different types of ... which can be arranged in any order in chains lasting 2000 units long enabling their variety. A protein is a specific number of amino acids assembled in a specific order. Peptide bonds are formed in amino acids be...

... and eukaryotic cell or multi-cellular, which have more complex interior. As the more complex cell, eukaryotic has various structures (organelles) in the cell. One of the most fundamental structures is the plasma membrane. In regard to the crucial roles of the plasma membrane, which is a part of ... can acts as a barrier for those polar substances, for example, amino acids, sugar and salts. Many protein and cholesterol embedded in plasma membrane particularly to the part that stick outside the cell also have carbohydrate group attached to them, this cholesterol is called glycolipid, which...
