Question

FINAL EXAM BIO 315 Exam I 1. Carbon is a major Chemical element in life. Which of the following examples is the most likely reason for that? a. Carbon can generate four covalent bonds. b. Carbon dating can be used to age c. Carbon mediates hydrogen bonding. d. Carbon-Carbon bond can be broken by UV light. 2. Which of the following processes is NOT involved in polymer formation? a. The generation of ATP b. The generation of water molecule c. Anabolism d. Increase in system entropy e. Activated Carrier 3. An oligomeric protein complex is composed of 4 identical subunits arranged in a symmetric way. It performs the conversion of Chemical-X to Chemical-Y. The protein complex has an allosteric binding sites for Chemical-Z, which upon binding, destabilizes the binding of Chemical-X and -Y. Which of the following trends best predicts the concentration of Chemical-Y over time? time Addition of Chemical-2Z 4. You want to study how fast a protein molecule can diffuse inside of a cell. Which of the following methods fit best for your goal? a. FRET (Fluorescence Resonance Energy Transfer) b. FRAP (Fluorescence Recovery After Photobleaching) c. Electron microscope d. RNAi e. Western blot analysis

Explanation / Answer

1. Option A is correct.
Carbon is tetravalent. It can form multiple types of compounds due to its catenation property.

2. Option D is correct.
A polymer formation involves joining of multiple monomers to form a single polymer. Hence it is accompanied by a decrease in entropy.

3. Option D is correct.
The addition of the compound inhibits protein function.

4. Option A is correct.
FRET is used to study molecular movements.

5. Option B is correct.
