Hauv ib voltaic cell , cov oxidation thiab txo cov hlau tshwm sim ntawm cov electrodes. Muaj ob lub electrodes hauv a voltaic cell , ib nrab ib nrab- cell . Lub cathode yog qhov chaw txo qis thiab oxidation yuav siv qhov chaw ntawm lub anode.

Xav txog qhov no, qhov twg oxidation tshwm sim hauv lub cell?

Oxidation siv qhov chaw ntawm lub anode ntawm electrochemical cell . Qhov no yog qhov uas cov hlau hauv anode poob electrons.

Ib sab saum toj no, yuav ua li cas tshwm sim hauv lub cell galvanic? A galvanic ( hluav taws xob ) cell siv lub zog tso tawm thaum lub sijhawm cov tshuaj tiv thaiv redox (ΔG<0) los tsim hluav taws xob. Lub oxidation ib nrab-reaction tshwm sim ntawm ib tug electrode (lub anode), thiab qhov txo qis ib nrab-reactions tshwm sim ntawm lwm yam (lub cathode).

Yog li ntawd, qhov twg oxidation tshwm sim hauv electrolytic cell?

Muaj ob hom electrodes hauv ib electrochemical cell , anode thiab cathode. Oxidation ib txwm tshwm sim ntawm lub anode thaum txo qis ib txwm tshwm sim ntawm cathode.

Puas yog ATP rau ADP oxidation?

Yuav los ntawm ATP to ADP thiab ib qho inorganic phosphate ib oxidation cov tshuaj tiv thaiv lossis kev txo qis, thiab vim li cas? ATP to ADP + Pi yog qhov txo qis; ADP yog daim ntawv txo. Qhov no yog vim qhov kev hloov hauv lub oxidation xeev. Txawm hais tias tus nqi tsis hloov, lub oxidation xeev txo.
