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...

Why would covalent bonds break in water? Why can they? - Because more stable or energetically favored bonds could be formed. They can break because the loss of energy by breaking hydrogen bonds in compensated for in the formation of new covalent bonds. Limitation to eukaryotic cells and photosynthesis - The sea slugs that live in symbiotic relationships with cyanobacteria or algae. The algae is not broken down or digested and absorbed into the slug's body. There is then a horizontal gene t...
