Bio 189 Midterm Study Guide Questions and Answers Rated A+ What role do telomeres play in cellular aging? Telomeres protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes, and their shortening during cell division is associated with cellular aging and limit the number of times a cell can divide. Describe how the structure of the phospholipid bilayer contributes to its function. The phospholipid bilayer's hydrophilic (water-attracting) heads face...

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...

TAMU EXAM 3 BIOL 111 Test Questions And Verified Correct Answers Photosynthesis can best be described as an _________ reaction. - ANSWER Endergonic Photosynthesis is overall an anabolic process, if we look at the photosynthesis summary reaction then we can call that overall reaction endergonic because it is building sugar. This means our reactants have less free energy than our products, which means we need a net input of energy. This source is the light energy that is brought...
