What does anaerobic mean?

• A. The way your body uses oxygen
• B. An abundance of oxygen
• C. With oxygen
• D. Without oxygen

Answer: (D)

Anaerobic means occurring without oxygen. In the body, it describes energy-producing processes that do not require oxygen, such as short, high-intensity efforts where the oxygen supply can’t meet demand, relying on anaerobic glycolysis and producing lactate. This is why the option that says without oxygen fits best. The other phrasings describe conditions with oxygen or an abundance of oxygen, which don’t match the term.
