Final answer:
Oxidation is the removal of electrons, typically accompanied by protons in a process known as dehydrogenation. It's one half of redox reactions, where reduction is the gain of electrons. The correct answer to the question is A) Electrons; Hydrolysis.
Step-by-step explanation:
Oxidation is defined as the removal of electrons. In biological systems, these are usually accompanied by protons in a process called dehydrogenation. Therefore, the correct answer is A) Electrons; Hydrolysis.
Oxidation can also be defined in several ways such as the addition of oxygen to a substance, the loss of hydrogen from a substance, or an increase in oxidation number. Conversely, reduction is when there is a gain of electrons, removal of oxygen, or addition of hydrogen to a substance, which leads to a decrease in oxidation number.
