Question

how do your cells produce enough atp to keep you alive? the answer — a process called cellular respiration — involves (1) a fundamental category of chemical reactions, and (2) a fundamental principle about how the universe works. the chemical reactions are about transferring energy. the fundamental principle is about transforming energy.
lets start with these two fundamentals, and then get into the details listed in the lo.
the chemical reactions that drive atp production are called reduction - oxidation reactions, or simply redox. officially, oxidation refers to the loss of electrons and reduction to the gain of electrons, meaning that the reaction removes or adds an electron to an atom.
a mnemonic is a phrase or other device used as a memory aid. for example, the mnemonic roy g. biv is useful for remembering the colors of the rainbow (red, orange, yellow, green, blue, indigo, violet).
why is the mnemonic oil rig useful for remembering how redox works?
○ loss of electrons is oxidation; gain of electrons is reduction—so leo the lion says ger.
○ oxidation is lazy electrons; reduction is growing electrons.
○ oxidation is loss; reduction is gain.
in organisms, though, redox reactions involve changes in electron position in a covalent bond instead of complete loss or gain of electrons. in cellular respiration, for example, c - c bonds in glucose get broken and the electrons involved end up in c=o bonds in carbon dioxide.
which diagrams correctly represent the position of shared electrons in c - c bonds and c=o bonds? select all that apply.

Explanation:

The mnemonic OIL RIG stands for Oxidation Is Loss (of electrons) and Reduction Is Gain (of electrons). This directly relates to the definitions of oxidation and reduction provided earlier (oxidation = loss of electrons, reduction = gain of electrons).

Answer:

Oxidation Is Loss; Reduction Is Gain.
