AP Biology Reading Guide/Homework Chapter 19

AP Biology Reading Guide Chapter 6: A Tour of the Cell. To study cells, biologists use microscopes and the tools of biochemistry 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses; and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain t...

AP Biology Reading Guide Chapter 15 and 16: Regulation of Gene Expression & Development, Stem Cells and Cancer. Compare and contrast the lac operon and the trp operon. (Remember that compare means “to tell how they are similar,” and contrast means “to tell how they are different.”) Lac is inducible and trp operon is repressible. They both have the three components of an operon: an operator, promoter, and regulatory gene. They are different because the trp repressor is inactive alone ...

AP Biology Reading Guide Chapter 15 and 16: Regulation of Gene Expression & Development, Stem Cells and Cancer. What are the two main ways of controlling metabolism in bacterial cells? Feedback inhibition: when the end product of a metabolic pathway goes back and inhibits the one of the enzymes that is active in that pathway. This stops the production of that product. Regulation of gene expression: mechanisms that are used by cells to increase or decrease the production of specific gene pro...
