Questions and Answers

What process is promoted by increased cellular metabolism in the nervous system?

  • Cardiogenesis
  • Neurogenesis (correct)
  • Osteogenesis
  • Dermatogenesis
  • What is the main purpose of converting lactic acid into lactate in the liver after exercise?

  • To induce muscle stiffness
  • To generate fuel for energy production (correct)
  • To inhibit neurogenesis
  • To increase muscle fatigue
  • What happens to lactate after being transformed in the liver following exercise?

  • It enters circulation to enhance growth and turnover of neurons (correct)
  • It gets excreted through sweat glands
  • It remains stored in muscle tissue
  • It converts back into lactic acid
