2. Explain the structural role of the four different categories of biomolecules within a cell.
3. Explain how water, a steroid hormone, and a monosaccharide are transported into a cell down their concentration gradient and explain why the different molecules are transported in different ways.
4. Explain which forms of transport require energy and why, and how ATP facilitates energy-dependent transport.
5. All of the different types of biomolecules can serve as energy sources. Explain which biomolecules are catabolized in which metabolic pathways.
6. Whether or not the cellular machinery is in place for particular catabolic reactions to go forward depends on which genes are being expressed. Explain the different points, in a eukaryotic cell, at which gene expression might be regulated, and how.
7. The primary tasks of any organism are survival and reproduction. Acquiring biomolecules and catabolizing them to generate energy is a major factor in survival. For reproduction to occur, DNA must first be replicated so that it can be passed on. Describe the process of DNA replication.
8. If you wanted to replicate DNA artificially in large quantities, how would you go about it?
9. Once DNA has been replicated, what is the sequence of events in the cell cycle and in cell division that produce the gametes for sexual reproduction? Where does this event fit, along with other cell cycles, in the life cycle of the organism?
10. A number of physical traits in humans are controlled by a simple dominant/recessive relationship between two alleles; here are some examples (dominant/recessive):
Widowâs peak/no widowâs peak
Free earlobes/attached earlobes
Cleft chin/no cleft chin
Dimples/no dimples
Freckles/no freckles
Naturally curly hair (really curly, not wavy)/straight hair
Make a pedigree of your immediate family indicating the possible genotype of each family member (for the six genes listed above) based on their phenotype. If you are adopted, indicate the possible genotypes and phenotypes of your parents. You may make this part up.
