Which of the following could be represented by X and Y, if X is directly changed into Y?
X= protein and Y= amino acids

Describes the properties of the phospholipid bilayer?
The head region is called hydrophilic because they do interact with water molecules. The tail region is called hydrophobic because they do not interact with water.

A sample of red blood cells are placed in an isotonic solution and viewed under the microscope. Then, sugar is added to the solution. The cells are viewed under a microscope again.
Which question might a student ask about what they see?
Did the red blood cells release water through osmosis because the sugar solution is hypertonic to the red blood cells?
400
According to the graph above, what is the ideal temperature for the enzyme?
40 degrees

Two products of respiration are _______.
Carbon Dioxide and Water
500
What are some roles that proteins play in the cell membrane?
To transport substances across the membrane and provide structure for the membrane.
500
Compared to small cells, large cells have more trouble.....
Transporting substances in and waste products out due to surface area to volume problems and stress on the membrane

Why do plant cells NOT burst when placed in hypotonic solutions? (AKS 1a)
The cell membrane pushes against the cell wall and the cell wall prevents bursting. This is called plant turgor.

In what way could you increase the rate of the reaction as it is taking place in Model C?
Add more enzymes to the reaction.
