PCB 3134 Exam 3 (definitions) - Questions with
Correct Answers (Verified Update)
62 questions with answers
Topic: PCB 3134 Exam 3 (definitions)
1. anabolic vs catabolic
Answer: anabolic: building molecules, decreasing entropy, needs energy
2. phosphoanhydride vs phosphoester
Answer: phosphoanhydride: between phosphate groups
3. chemotroph
Answer: gain energy from chemical compounds (usually involves oxidation reactions)
4. oxidation vs reduction
Answer: oxidation: dehydrogenation (removing hydrogen and electrons)
5. coenzymes
Answer: help enzymes in reactions by carrying electrons or small functional groups
6. obligate anaerobes vs obligate aerobes vs facultative organisms
Answer: obligate anaerobes cannot take in oxygen
7. phases of glycolysis
Answer: phase 1: preparation and cleavage
8. kinase vs phosphatase
Answer: kinase adds a phosphate group
9. important steps of glycolysis
Answer: 1 and 3 require ATP input
10. lactate fermentation vs ethanol fermentation
Answer: lactate: pyruvate to lactate via NADH oxidation
11. apical vs basal
Answer: apical is at the top out in the open (external environment), basal touches the
connective tissue at the bottom
12. three types of junctions
Answer: adhesive, tight, gap
13. adherens junctions
Answer: cadherin-mediated junctions that interact with actin (MFs)
14. E-cadherin structure
Answer: five repeated extracellular segments, one transmembrane segment, one
cytoplasmic segment
15. beta vs alpha vs p120 catenins
Answer: beta catenin: links E-cadherin to alpha catenin
