Biomolecules PreAssessment

The cell membrane is made up of lipids, and it uses those lipids to:

• 1. Provide internal and external structure

• 1. Permit changes in external conditions

• 1. Restrict the movement of materials across it

• 1. Remove waste products from the cell

Proteins make up enzymes in the cell. One example of an enzyme is the ribosome. What does protein do in the ribosome?

• 1. Assign different regions of the ribosome different tasks

• 1. Enhance the productivity of the ribosome in different conditions

• 1. Chemically interact with different materials around the ribosome

• 1. Provide shape and structure for the ribosome

The cell nucleus contains the cell’s genetic material in the form of a nucleic acid called DNA. What is the purpose of DNA in a cell?

• 1. Allow for the removal of waste products

• 1. Enhance reaction speeds to increase production

• 1. Provide internal structure for the cell

• 1. Store instructions for different traits

Enzymes' primary purpose in a cell is to do what?

• 1. Create internal structures for the cell

• 1. Increase the pace of reactions

• 1. Produce new reactions at greater efficiency

• 1. Maintain a stable internal environment

Enzymes only function in specific internal conditions. Which of the following best explains this behavior of enzymes?

• 1. Enzyme shape changes as conditions change

• 1. Enzymes stop bonding to chemicals when changes happen

• 1. Changes cause enzymes to shake themselves apart

• 1. Enzymes are more likely to avoid reactions when changes happen
