  1. The series of reactions involving the conversion of glucose to pyruvate is known as
    glycolysis
  2. when energy-yielding nutrients are consumed in excess, which ones can lead to storage of fat
    fat, carbohydrate, and protein
  3. in photosynthesis, the plant uses energy from the sun, plus water and co2 to synthesize
    carbohydrates only
  4. in addition to energy, what are the principal end products of cellular oxidation of carbohydrates
    water and Co2
  5. what is the immediate fate of excess dietary protein in the body
    deaminated
  6. approximately how many ATP molecules are synthesized from the complete oxidation of a molecule of palmitic acid
    129
  7. which of the following outlines the overall sequence of events in the complete oxidation of glucose
    glycolysis, TCA cycle, ETC
  8. what term is specific to reactions in which simple compounds are combined into more complex molecules
    anabolic
  9. ketonemia is defined as an elevation of
    ketones in the blood
  10. of the total amount of carbohydrate energy consumed by the body, approximately what percentage is used by the brain and nerve cells
    60
  11. what organ is the major site for gluconeogenesis
    liver
  12. A person said to have acetone breath most likely has the condition known as
    ketonemia
  13. which is not an aspect of glycolysis
    it is irreversible
  14. a feature of ketosis is that it
    occurs when fats are partially oxidized
  15. which reaction is an example of an anabolic reaction
    cholesterol synthesis from acetyl CoA molecules
  16. When protein consumption is in excess of body needs and energy needs are met, the excess amino acids are metabolized and the energy in the molecules is
    stored as glycogen and fat
  17. which is used to supply some of the fuel needed by the brain only after the body has been fasting for a while
    ketones
  18. an aerobic reaction is one that requires
    oxygen
  19. which can be synthesized from all three energy-yielding nutrients
    acetyl CoA
  20. which defines a moderate level of alcohol intake per day for the average-sized man
    up to 2 drinks
  21. The amount of ethanol in a typical drink is
    0.5 ounce
  22. in the adult body, food energy not stored as fat or glycogen is lost as
    heat
  23. which is true regarding alcoholic beverages containing caffeine
    the FDA has banned their sales
  24. a feature of catabolic reactions is that they
    involve release of energy
  25. excess alcohol intake leads to a reduction in the synthesis rate of
    liver glucose
  26. at what point is oxygen used in the ETC
    at the end
  27. where do the TCA cycle reactions take place
    inner compartment of the mitochondria
  28. which of the following accounts ffor the higher energy density of a fatty acid compared with the other energy-yielding nutrients
    fatty acids have a greater percentage of hydrogen-carbon bonds
  29. which is a characteristic of alcohol use
    ingestion of alcohol cools the body
  30. which is a consequence of alcohol intake
    ADH production is suppressed
  31. the metabolism of alcohol begins in the
    stomach
  32. what is the major energy carrier molecule in most cells
    ATP
  33. what minimum concentration of blood alcohol leads to impaired judgement and increased heart rate
    0.05
  34. with alcoholic beverages, the ratio of proof to alcohol percentage is
    2:1
  35. which is a feature of aerobic metabolism
    energy is produced more slowly than in anaerobic metabolism
  36. what is another way for a doctor to diagnose ketosis
    fruity odor on breath
  37. which product is not generated via the TCA cycle or the ETC
    ammonia
  38. which dietary nutrient would most rapidly reverse a state of ketosis in a starving person
    carbohydrate
  39. what is acetaldehyde
    an intermediate in alcohol metabolism
  40. difference b/t men and women drinking
    women have less stomach alcohol dehydrogenase enzyme and consequently absorb more of the alcohol into the bloodstream
  41. when protein consumption is in excess of body needs and energy needs are met, the excess amino acids are metabolized and the energy in the molecules is
    stored as glycogen and fat
  42. if the carbohydrate content of the diet is insufficient to meet the body's needs for glucose, which can be converted to glucose
    amino acids
  43. the effects on metabolism from starvation are similar to those from
    fasting
  44. which is not among the functions of the liver
    production of red blood cells
  45. the formation of glycogen by the liver cells is an example of
    anabolism
  46. where to the TCA cycle reactions take place
    inner compartment of the mitochondria
  47. how does excess carbohydrate intake contribute to obesity
    it spares oxidation of body fat and dietary fat
  48. which is a feature of the metabolism of surplus dietary fat
    excess fat is almost all stored
  49. which is a characteristic of ketosis
    it may lead to a lowering of blood pH
  50. which compound cannot be formed from fatty acids
    glucose
  51. which reaction is an example of an anabolic reaction
    cholesterol synthesis from acetyl CoA molecules
  52. ketonemia is defined as an elevation of
    ketones in the blood
