Which of the following statements is not true of most cellular redox reactions?
1. the reactant that is oxidized loses electrons.
2. changes in potential energy can be released as heat.
3. a hydrogen atom is transferred to the atom that loses an electron.
4. the electron acceptor is reduced.

The statement that is not true as regards cellular redox reactions is C:A hydrogen atom is transferred to the atom that loses an electron.

Therefore, the third option is correct.

3. A hydrogen atom is transferred to the atom that loses an electron.

Explanation:

The reaction where one loses the electron and other gains the electron is called as the redox reaction. In redox reaction both oxidation reaction and reduction reaction takes place.

The above statement is false because often hydrogen atom is transferred to the atom that gains the electron not the one that loses an electron. The proton or the H+ ion is attracted to the atom gaining an electron in the cellular redox reaction.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.
