A plant is grown with its roots in a nutrient solution. A pump normally adds air to the solution.
The pump stops working, so very little oxygen reaches the root cells. The cells continue to break down glucose by anaerobic respiration.
State the two products of anaerobic respiration in the root cells.
State the part of the root cell where anaerobic respiration takes place.
Give one reason why anaerobic respiration releases less energy from each molecule of glucose than aerobic respiration.
