In a laboratory investigation students measure the rate of fermentation in yeast cells data was collected by the students group showing how the rate of fermentation is altered by: 1. PH of the reaction mixture; 2. Amount of yeast added to the reaction mixture; 3. Type of sugar added to the reaction mixture.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
