Question

20. Word bank: Hydrophili Triacylglycerols Fatty acids Hydrophobic Amylopectin Phospholipids Glucose can form large polymers that are held together by Animals store glucose in long, branched polymers called glucose in long, linear polymers called called the enzyme for degrading Steroids Hydrophilic Cholesterol Cellulose Glycoproteins bonds. Plants store or as branched polymers Animals can digest these polysaccharides, but most lack which serves as dietary fiber Lipids are be stored or broken down for energy down to produce energy. Lipids are stored as Membranes contain mostly groups. The lipid composition of membranes affect their fluidity. Long, saturated, and symmetrical lipids [increase/decrease] membrane fluidity, while short, unsaturated lipids (increase/decrease) fluidity fluidity. It helps increase flui compounds. They comprise cellular membranes and can are brokern with negatively charged head Is a heterocyclic compound that helps regulate membrane dity at low temperatures and decrease fluidity at low temperatures. It is also a precursor to a class of highly nonpolar hormones called These signaling molecules can cross cell membranes and bind directly to nuclear receptors 21. Circle all of the following that are NOT permeable through the cell membrane. Ethanol CO Cholesterol Hemoglobin Sodium ion Water 22. Put the following in order from weakest (1) to strongest (4). Salt bridges Dispersion forces Dipole-dipole interactions Hydrogen bonds 3. What types of damage are repaired by these pathways? Name proteins involved for extra points. Nucleotide excision repair c. a. Mismatch repair d. Homologous repair and NHE b. Base excision repair
