Why is a substance that undergoes reduction specifically referred to as an 'oxidising agent'?

In a zinc–manganese dioxide dry cell battery, the redox processes at the electrodes can be represented by the following half-equations:

\text{Anode: } \text{Zn(s)} \rightarrow \text{Zn}^{2+}(\text{aq}) + 2e^{-}

Which of the following statements correctly describes the redox nature of cellular respiration?

True or False: In any redox reaction, oxidation can occur independently without a corresponding reduction process taking place.

If an element in a chemical reaction undergoes a change where its oxidation state moves from $+2$ to $+4$ , which statement correctly describes the electron transfer involved?
