Do Metabolite Transport Processes Limit Photosynthesis?

Do metabolite transport processes limit photosynthesis?

Metabolite transport proteins occupy key positions in the metabolic networks of highly compartmentalized eukaryotic cells. In such cells, at least one and frequently more than one membrane delineate organelles from the cytosol. Thereby compartments with different reactions milieus are created that are characterized by low pH or high-energy status, or by highly reductive or oxidative conditions,...

Mitochondrial metabolite transport.

The flux of a variety of metabolites, nucleotides and coenzymes across the inner membrane of mitochondria is catalysed by a nuclear-coded superfamily of secondary transport proteins called MCs (mitochondrial carriers). The importance of MCs is demonstrated by their wide distribution in all eukaryotes, their role in numerous metabolic pathways and cell functions, and the identification of severa...

When Do Rocks Move? Sediment Transport and Geomorphic Processes

Carbon metabolite feedback regulation of leaf photosynthesis and development.

Photosynthesis is regulated as a two-way process. Light regulates the expression of genes for photosynthesis and the activity of the gene products (feedforward control). Rate of end-product use down-stream of the Calvin cycle, determined largely by nutrition and temperature, also affects photosynthetic activity and photosynthetic gene expression (feedback control). Whereas feedforward control e...
