proton gradient
[/ˈproʊtɑːn ˈɡreɪdiənt/]
nounpl: proton gradients
gradiente de prótons
1. A difference in proton concentration across a biological membrane, creating an electrochemical potential that drives ATP synthesis in cellular respiration and photosynthesis
The proton gradient established across the inner mitochondrial membrane is essential for ATP production.
O gradiente de prótons estabelecido através da membrana mitocondrial interna é essencial para a produção de ATP.
2. The concentration differential of hydrogen ions (H+) between two compartments separated by a semipermeable membrane
Photosynthesis creates a proton gradient in the thylakoid membrane that powers ATP synthase.
A fotossíntese cria um gradiente de prótons na membrana do tilacóide que alimenta a ATP sintase.
This is highly specialized scientific terminology used primarily in biochemistry, cell biology, and bioenergetics education and research. Both Brazil and Portugal use this term in academic and professional scientific contexts, with the only difference being the spelling variation between Brazilian 'prótons' and European Portuguese 'protões'. The concept is fundamental to understanding cellular energy production taught in secondary and higher education science curricula.
