​STAAR Biology Review

I am learning biomolecules and enzymes.

​​Learning Goal:

1. I can relate the functions of different types of biomolecules.

2. I can investigate and explain the role of enzymes in facilitating cellular processes.

​​Success Criteria:

5A: Relate the functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids, to the structure and function of a cell.

​

Multiple Choice

Actin is a protein that helps the cell maintain its shape and polarity. It also plays a major role in muscle construction. A table summarizing the cellular functions of different types of proteins is shown. Based on this information, actin is most likely -

• an enzyme protein

• a structural protein

• a messenger protein

• a transport protein

Multiple Choice

Rennin is an enzyme that catalyzes a reaction that solidifies milk. Rennin was added to three different test tubes with milk. Each test tube was placed in a water bath for ten minutes. The data collected during the experiment are shown. Which statement best explains the results of test tube 3?

• The enzyme changed the product

• The substrate was used up

• The enzyme was denatured

• The substrate reacted with the enzyme

Multiple Choice

Enzymes are biological catalysts and function by:

• increasing free energy in a system

• lowering the activation energy of a reaction causing the reaction to speed up

• eliminating entropy in a system

• increasing temperature near a reaction
