A scientist places germinating pea seeds in two containers. Air is passed continuously through container R. Nitrogen gas is passed continuously through container S, so no oxygen is present.
Which row correctly compares the breakdown of glucose and the energy transferred from each glucose molecule in the seeds?
R: complete breakdown, more energy transferred; S: incomplete breakdown, less energy transferred
R: complete breakdown, more energy transferred; S: incomplete breakdown, no energy transferred
R: incomplete breakdown, less energy transferred; S: complete breakdown, more energy transferred
R: complete breakdown, less energy transferred; S: incomplete breakdown, more energy transferred
