BIO 202 TEST BANK UPDATED QUESTIONS
AND ANSWERS FULL STUDY SHEET
●● Radioactive Isotopes
Answer: - Cytotoxic agents: help kills cancer cells
- Induce mutations: large DNA deletions
- Biological tracers: label molecules
●● Water
Answer: - H bonds give water its cohesiveness
- Stabilize temperature (high specific heat capacity)
- Expansion upon freezing
- Solvent versatility (bc its polar and ionic)
●● pH
Answer: - Change in pH is very harmful
- Buffers (weak acids or bases) can be used to keep pH constant
- pH of 4.0 = 10^-4 H+ ions
- pH rises = forward reaction
- pH drops = reverse reaction
- -log(H+)
, ●● Simple Sugars
Answer: - Carbohydrates; Monosaccharides; Glucose
- Bases to nucleotides
- Bases
- Exchange sugar for ATP
- Deoxyribose (does not have oxygen at carbon 2
- Ribose (does have have oxygen at carbon 2)
●● Fatty Acids
Answer: - Hydrophilic head and Hydrophobic Tail
- Sources of food (more energy than glucose)
- Stored as triglycerides and phospholipids
- No C=C bonds = Saturated
- C=C bonds = unsaturated (create bends preventing dense packing)
●● Hydrophilic Head (Fatty Acids)
Answer: Contains a carboxyl group
●● Hydrophobic Tail (Fatty Acids)
Answer: Long chains of C-C Bonds
●● Cholesterol
