What name is given to the process seen in this animation? (monomers: OH-OH and OH-OH get connected by polymerase which squeezes the monomers together and creates the chain OH-O-O-OH because it squeezes the middle OH and OH together to create H2O and leaves one O leftover, which allows the chain to continue) - CORRECT ANSWER dehydration synthesis: the linking of the monomers involves the removal of water Glycogen is ___ - CORRECT ANSWER A polysaccharide found in animals: animals store energy in the form of glycogen Glucose + Glucose --- __by__ - CORRECT ANSWER maltose + water... dehydration synthesis: maltose is the disaccharide formed when two glucose molecules are linked by dehydration synthesis Which of these is a source of lactose? - CORRECT ANSWER milk: lactose is the sugar found in milk Which of these is a polysaccharide? - CORRECT ANSWER cellulose: cellulose is a carbohydrate composed of many monomers ___ is the most abundant organic compound on Earth - CORRECT ANSWER Cellulose: a component of plant cell walls, is the most abundant organic compound found on earth Which of these is NOT a lipid? - CORRECT ANSWER RNA: which is a nucleic acid This figure is an example of a: h h-c-c^o-c(h-n)-c(h-n)-c(h-n)-h h-c- c^o-c(h-n)-c(h-n)-c(h-n)-h h-c- c^o-c(h-n)-c(h-n)-c(h-n)-h h - CORRECT ANSWER saturated fat which of these is a phospholipid - CORRECT ANSWER Phospholipids are composed of a phosphate group, a glycerol, and fatty acids O== Which of these is rich in unsaturated fats? - CORRECT ANSWER olive oil: is a plant oil, and most plant oils are rich in unsaturated fats A function of cholesterol that does not harm health is its role ___ - CORRECT ANSWER as a component of animal cell membranes: cholesterol is an important component of animal cell membranes Proteins are polymers of ___ - CORRECT ANSWER amino acids: proteins are polymers of amino acids What type of bond joins the monomers in a protein's primary structure? - CORRECT ANSWER Peptide: the amino acids of a protein are linked by peptide bonds Which of these illustrates the secondary structure of a protein? - CORRECT ANSWER Alpha helices and beta pleated sheets are characteristics of a protein's secondary structure: looks like many curly-ques The secondary structure of a protein results from ___ - CORRECT ANSWER hydrogen bonds: electronegative oxygen and nitrogen atoms leave hydrogen atoms with partial positive charges Tertiary structure is NOT directly dependent on ___ - CORRECT ANSWER peptide bonds: peptide bonds link together the amino acids of a protein's primary structure.
