Exam points
- explain nitrate-ion uptake when soil concentration is lower than concentration inside root hair cells
- link oxygen and glucose to respiration, released energy and continued active transport
- trace how reduced root respiration can lower nitrate uptake, amino-acid supply and plant protein synthesis
