6501 Walden University questons and
answers
A runner has depleted all the oxygen available for muscle energy. Which of the
following will facilitate his continued muscle performance? - ANSWER>>ANSWER:
Anaerobic glycolysis
What causes the rapid change in the resting membrane potential that initiates an
action potential? - ANSWER>>ANSWER: Sodium gates open, and sodium rushes
into the cell, changing the membrane potential from negative to positive.
A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would
reveal which of the following? - ANSWER>>ANSWER: XXY
