Why are 4 H+ needed for every ATP synthesized and exported by mitochondria, even though only 3 H+ need to be translocated by the
kykrilka [37]

Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP

Que signifie ADN et comment on le prouve?
irakobra [83]

Answer:

<h3>Qu'est-ce que l'ADN ?</h3>

L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.

Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".

Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

J'espère t'avoir aidé, bonnes études !
