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...

IB Biology 1.5 Latest Version Already Graded A Endosymbiotic theory a theory that some eukaryotic organelles, such as mitochondria and chloroplasts, originated as free-living prokaryotes that invaded primitive eukaryotic cells. Allowed growth of smaller cells in a cytoplasm, through endocytosis, and the rapid replication they could persist indefinitely inside the large cells. It also states that mitochondria were once free living prokaryotic organisms that had developed the process ...

The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - Correct answer-true In your own multicellular body, cells with different functions have different DNA. - Correct answer-false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - Correct answer-true The paramec...

ASU Bio 181 Quiz 1 The association of ribosomes with _____ invaginations would support the _____ theory. - correct answer membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walk is? - correct answer filipodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. - correct answer true T/...
