Membrane Transport Systems of Plant Mitochondria

摘要: Mitochondria are loci of intense oxidative activity in the plant cell, accounting for bulk oxygen consumption. Operation TCA cycle (Chap. 10) matrix oxidized substrate organic acids to CO2 and H2O with production NADH reduced flavoprotein, which turn by O2 through respiratory chain inner-membrane, producing ATP 6). In addition, partial operation or transamination deamination produces products utilized intermediary metabolism cell. Both functions, formation participation metabolism, require regulated transport ions metabolites between cytosol mitochondrial matrix. also carry out transcription-translation matrix, requires uptake nucleotides amino from cytosol. Plant mitochondria may participate regulation free Ca2+ levels release Ca2+. general terms, selective functions complex web metabolism.
