Abstract
Phosphoenolpyruvate (PEP) was transported together with H+ in C-4 meso phyll chloroplasts. Medium alkalization and stromal acidification due to pyruvate uptake into maize mesophyll chloroplasts in the light were partially inhibited by adding PEP. Thus, the H+ taken up by H+/pyruva te cotransport into mesophyll chloroplasts is released together with P EP in vivo.
