You learned about the lock and key model to explain how enzymes work. Match the numbers to the components of the lock and key model.

Match the description in the left column with the correct terms in the right column.

Red blood cells are placed in a container with fluid. The concentration of water outside the red blood cells is greater than the concentration of water inside the red blood cells.  What type of tonicity does the outside environment exhibit? What will happen to the cell over time?

Match the macromolecules with their monomers

You learned about nucleic acids.  Fill in the blanks from what you learned in lecture about nucleic acids. The monomers of nucleic acids are [answer1]. These monomers are made of a pentose sugar, a nitrogen-containing [answer2], and a [answer3] group. DNA is [answer4]-stranded. The sugar in DNA is deoxyribose while the sugar in RNA is [answer5]. 

Name the four things that all cells have in common.    

There are 2 general types of cellular transport: passive transport and active transport.  We discussed different examples of cellular transport like diffusion, the sodium-potassium pump, osmosis, facilitated transport, and phagocytosis.  Compare and contrast passive transport and active transport by describing an example for each type of cellular transport to illustrate how each example illustrates passive transport and passive transport.  Remember to use your own voice and describe what you learned about diffusion and osmosis to illustrate their similarities and differences from the examples we learned in class.

Compare and contrast prokaryotic cells vs eukaryotic cells.  Include examples of organisms that have these cells that you learned about in our lectures and lab exercises in your answer. Use your own voice and include examples you learned from class to describe prokaryotic cells and eukaryotic cells and to illustrate their similarities and differences.

A biologist isolates a large, unidentified molecule from some cells in their lab. They determine that the macromolecule breaks into smaller pieces when water is added. What reaction have they observed?

You learned about the characteristics of water and the important role it plays in our lives and our communities. Describe an example you discussed with your classmate in our The Importance of Water Discussion Assignment, that illustrates why water is important for our health, and how equitable access to clean water affects every day lives of people and their communities.
