Where would you expect to find electron transport chains in a prokaryote?

The electron transport chains in a prokaryote can be found along in the plasma membrane.

Explanation:

The electron transport chain is the arrangement of transportation of electrons in the inward mitochondrial district. This procedure is the major O2 buyer. This chain passes the electrons from NADH to atomic oxygen through the ATP synthase activity.  

The chain likewise connects the electron to protein buildings. Since this Atomic oxygen is the last component that gets the electron in the electron transport chain.

So finally, the explanation is you need oxygen, so your phones can utilize this atom during oxidative phosphorylation, the last phase of cell breath.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
