Which statement about uncouplers is not true? a. they allow atp synthesis with no electron transport. b. they allow electron transport without atp synthesis. c. their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side. 2,4-dnp is an example of an uncoupler.

the statement that is wrong about uncouplers is option A ( they allow ATP synthesis with no electron transport).

Explanation:

An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.

2,4-DNP is an example of an uncoupler.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
