Biomedical Engineering Final Exam with correct answers

a large molecule that consists of many repeating structural units is called acorrect answerpolymer each unit molecule that comes together to form a polymer is called acorrect answermonomer the main advantage associated with ceramics compared to metals iscorrect answercorrosion resistance what all polymers have in common is the type of bond which holds their monomers together. what type of bond is this?correct answera covalent bond there are two types of polymerization, the first being addition, which of these is a requirement of monomers in order to undergo addition polymerization?correct answerthe presence of a carbon to carbon double bond as mentioned earlier, there are two main types of polymerization, the second of which is condensation polymerization. during a condensation polymerization reaction, many monomers join together. what is lost when two monomers join together via a condensation reaction?correct answerwater proteins (polypeptides) and carbohydrates (polysaccharides) are both polymers. true or false, the third of the major biological molecules, the lipids, cannot be described as ct answertrue still on biological molecules, the incredible length of these polymers (sometimes tens of thousands of monomers) often results in the formation of a tertiary, 3-D structure. an example of this is in globular proteins. which of these is NOT a force of attraction which usually acts between the different sections of the polypeptide chain of a globular protein?correct answermetallic bonds Which of the following structures represents a polyamide?correct answer[-NH-CO-R-] Which of the following structures represents an anhydride?correct answerR-COOCOR GPC is one of the methods to measure molecular weight of the polymers. define the acronym, GPC.correct answerGel Permeation Chromatography In general, metals are more corrosion-resistant than ceramicscorrect answerFalse, metals are not more corrosion resistant amorphous polymers have ordered chain configurationcorrect answerfalse, amorphous polymers don't have ordered chains
