AP Bio Unit 1 Exam Review

What is the property that best explains why the meniscus of water is concave?

• Polar covalent bonds cause the water to become more attracted to the walls than each other.

• Surface tension pulling the water down.

• Cohesion is stronger than adhesion.

• Adhesion is stronger than cohesion.

You have a chain of amino acids that includes both polar and non-polar molecules. What is most likely to cause a significant change on the structure and therefore function?

• Replacing a non-polar molecule with another non-polar molecule.

• Replacing a polar molecule with a different polar molecule.

• Replacing a polar molecule with a non-polar molecule.

• Nothing will change it.

Though all are important, one of the most significant levels of protein structure occurs when interactions between the side chains of amino acids occurs, which is during what level?

• Primary

• Secondary

• Tertiary

• Quaternary

5'- GCATGATCA -3'

DO NOT PUT ANY SPACES IN YOUR RESPONSE

If a fatty acid chain is UNSATURATED, that means it...

• Has one or more double bonds, which gives it more flexibility in cell membranes when in cold temperatures.

• Has no double bonds and is extremely saturated with hydrogen.

• Has no double bonds, which gives it more flexibility in cell membranes when in cold temperatures.

• None of the above.

Phosphorus is required for building which macromolecule(s)?
