Verified step by step guidance

Understand the concept of oxidation and reduction in the context of electron transfer. Oxidation involves the loss of electrons, while reduction involves the gain of electrons.

Recall the mnemonic 'OIL RIG' which stands for 'Oxidation Is Loss, Reduction Is Gain' to help remember the electron transfer process.

Consider the role of oxidation and reduction in redox reactions, where one substance is oxidized (loses electrons) and another is reduced (gains electrons).

Identify the correct answer from the options provided: 'Loss of electrons; Gain of electrons' aligns with the definitions of oxidation and reduction.

Reflect on the importance of these processes in biological systems, such as cellular respiration, where electrons are transferred to produce energy.
