Sean Byrne Teacher Biology Honors 13 August 2014 Unit 1 Chapter 3 1) a. Monomers are small‚ simple molecules that when put together create carbon compounds‚ and polymers are molecules that consist of repeated units. b. Functional groups are made of clusters of atoms‚ while macromolecules are large polymers. c. A monosaccharide is a simple sugar‚ but a disaccharide is known as a double sugar‚ or two monosaccharaides. d. Long chains of amino acids are called polypeptides‚ and proteins are composed

A maximum of 20 pts may be added to your first exam 20 x (correct pts / total pts) Question 1 Actin and tubulin form self-assembling polymers. Where on the filaments do subunits exchange with free monomers? Subunit exchange with free monomers occurs at the end of filaments. In actin filaments‚ subunits can be freely exchanged at both ends of the filament (pointed and barbed ends) until

plastics together is a new concept to many people. In reality‚ polymers are not like salt‚ which is totally crystalline‚ but are semi-crystalline. Unlike crystals like salt‚ polymers have only short-range order and a much looser organization. Crystallinity is one of the great divisions of the complete family of plastics. Amorphous polymers (those with no significant degree of crystallization) behave very differently than crystalline polymers (those with a significant degree of crystallization). Understanding

She began work at DuPort research Laboratory where she conducted low-temperature experiments for preparation of polymers for the creation of highly rigid and strong petroleum-based fibres. Kwolek made a solution that caused unstable intermediates from these experiments to bond into long chains. Under these conditions‚ the polymers formed a cloudy fluid in contrast to the clear and sticky
