1

The diagram below shows the bonding interactions of individual water molecules with multiple other water molecules. Label the diagram below with the letters shown on the right.

The first falling leaf of the season has tumbled from the air and landed on the top of the pond. It does not sink but yet float on top of the surface. What is happening on a molecular level that is preventing the leaf from sinking?

1

Which of the following best describes the significance of water's high specific heat capacity in living organisms?

1

In which situation is adhesion more prominent than cohesion?

1

In living cells, carbon serves as the backbone for a wide range of organic molecules. Which of the following is NOT a major role of carbon in living organisms?

1

Roger is comparing a model of a sugar molecule to a model of an amino acid. Which of the following evidence statements would be supported by the two models?

1

Scientists have found a new biological sample in the Great Salt Lake. They were testing the sample to determine its chemical composition. The sample got mixed up in the lab, with a ice core sample. Which of the following is most likely the chemical results from the new biological sample?

1

Butter, oil, wax, & cholesterol are examples of _, which are made up of the elements _____.

1

A biological macromolecule (DNA or RNA) composed of which elements?

1

Like complex carbohydrates, proteins are biomolecules that serve many functions and can be chemically broken down and restructured. Both proteins and complex carbohydrates are which of the following?

1

Resistance to antibiotics results from the differences in genetic information of Streptococcus pneumoniae. Which type of molecule is responsible for genetic information in Streptococcus pneumoniae?

1

Proteins have a wide range of functions in living organisms. How does the structure of a protein relate to its function, and can a change in protein structure affect its function?

1

In recent research there has been controversy over reduced fat diets. On the one hand, a low fat diet is meant to lead to better physical health, like reducing plaque build-up in your arteries. On the other hand, lipids provide essential building blocks for cellular structures. Which one of these would be directly affected by a reduction of fat in the diet?

1

Match the name of the molecule to its function (drag and drop)

Meat tenderizer contains an enzyme that interacts with meat. If meat is coated with tenderizer and then placed in a refrigerator for a short time, how would the enzyme be affected?

1

Catalase is an enzyme that speeds up the decomposition of hydrogen peroxide into water and oxygen. Students conducted two investigations to determine the ideal conditions for the function of catalase. One investigation compared catalase activity at different values of pH. The other investigation compared catalase activity at different temperatures.

According to the data in the graphs, which pH and temperature combination provides the best conditions for catalase to function?

1

The graph below shows the effect of temperature on the relative rate of action of enzyme X on a protein. Which change would not affect the relative rate of action of enzyme X?

1

Proteins are essential for a wide range of cellular processes. Describe the role of enzymes, a specific type of protein, in facilitating chemical reactions and explain how enzymes achieve specificity.

1

A scientist is using an enzyme to get a chemical reaction to occur within a cell sample and records the data below about the rate of reaction in different pH environments. What does the data most likely demonstrate about the enzyme?
