CHEM 210 BIOCHEMISTRY MODULES 1–8 & FINAL EXAM () TITUS LEARNING PROVED QUESTIONS AND 100% VERIFIED ANSWERS

1. What is biochemistry? QUICK FIX the chemistry of life 2. Molecular arrangements QUICK FIX linear= 180 degrees trigonal planar= 120 degrees 3. trigonal pyramidal= 107.5 degrees tetrahedral= 109.5 degrees 4. bent= 104.5 degrees 5. How many of the 90 naturally occurring elements are found in living organisms? QUICK FIX less than 30 (small nonmetal in upper right of the table) 6. smaller vs larger element bonds QUICK FIX smaller elements are favored because they can form stable covalent bonds (strong), the larger elements do not form stable covalent bonds 7. What elements is critical to all living things and is found in large amounts? QUICK FIX Carbon 8. Organic vs inorganic chemistry QUICK FIX organic-study of carbon based compounds, inorganic- study of compounds typically not 9. containing carbon 10. Carbon QUICK FIX -has 4 valence electron permitting it to form 4 bonds 11. -forms long chains 12. -forms double and triple bonds 13. -forms ring compounds (cyclic compounds) 14. forms bonds w many other atoms including H, N, and O 15. Alkanes QUICK FIX Straight chain compounds with only carbon and hydrogen 16. chemical and compounds formulas of the QUICK FIX methane= CH4, 17. CH4 18. ethane= C2H6, CH3CH3 19. propane= C3H8, CH3CH2CH3 20. butane= C4H10, CH3CH2CH2CH3 21. pentane=C5H12, CH3CH2CH2CH2CH3 22. hexane=C6H14, CH3CH2CH2CH2CH2CH3 23. heptane=C7H16, CH3CH2CH2CH2CH2CH2CH3 24. *starting from CH4 add one carbon and two hydrogens in the 25. chemical formula and add one CH2 in each with CH3 on both ends
