BIOS 242 Week 4 Midterm: Unit 1 – 4 Practice Questions
1. Anabolic reactions characteristics
Require energy and a source of precursor metabolites
2. Chemical reactions that can proceed toward either anabolism or catabolism are called what?
Amphiobolic Reactions
3. Catabolic reactions may be characteristics
Break down molecules
4. The molecule that an enzyme acts upon is known as called what?
Substrate
5. Enzymes known as lyases participate in what reactions?
Catabolic
6. Role of an enzyme in a chemical reaction in a cell?
Increase likelihood of a reaction; decrease activation energy
7. Which is glycolysis steps?
Energy-investment stage, lysis stage, energy-conserving stage
8. What is fermentation?
When cells cannot completely oxidize glucose by means of cellular respiration. Aerobic bacteria
undergo fermentation is false.
9. What is Krebs cycle?
10. Anaerobic bacteria use what as final electron acceptors in respiration?
