How are polymers formed and broken? - formed via dehydration(condensation) and broken due to hydration (hydrolysis dissolution of glycosidic bond) important amino acids - glycine= R=H very flexible proline= fixed, and very rigid R=secondary amino loop, prevent amino acid from alpha helices cystine= can form disulfide bridges methionine= also contains sulfur and is the start codon AUG

CELL BIO EXAM 3 QUESTIONS & ANSWERS what are the 6 major types of cell death - Answer-1. necrosis 2. apoptosis 3. autophagy 4. mitotic catastrophe 5. senescence 6. ferroptosis what are the two major reasons that cell-cell death is good - Answer-1. maximize killing cancer cells 2. to prevent genomic instability and malignant transformation due to damage in a normal cell (especially dsDNA breaks) This uncontrolled form of cell death is morphologically characterized by cell membrane swel...

Dehydration Small molecules combine to form larger ones. For example: sugar monomers combine to form starch polymers Hydrolysis One larger molecule is split by the addition of H+ and OH- (from water) to the components Polymers large chains of identical molecular units strung together Monomers the units that serve as the building blocks of polymers Another name for a dehydration reaction is... condensation reaction Cells contain ___ major families of sma...
