According to the "How the Experiment Was Done" section, what were the specific conditions under which the guinea pig red blood cells were incubated?

  • A: In a 300 mM radioactive glucose solution at pH 7.4 and 25°C.
  • B: In a 100 mM radioactive glucose solution at pH 7.0 and 37°C.
  • C: In a solution without radioactive glucose to measure baseline uptake.
  • D: At varying pH levels to test the effect of acidity on glucose uptake.

Explanation

The 'How the Experiment Was Done' section explicitly states: 'Researchers incubated guinea pig red blood cells in a 300 mM millimolar radioactive glucose solution at pH 7.4 at 25°C.'
