Question

All cells use oxygen to produce energy.

• A. True
• B. False

Answer 1

The correct option is B False

Not all cells use oxygen to produce energy. Aerobic cells use oxygen to produce energy. Anaerobic organisms do not require oxygen to produce energy. They obtain energy from metabolism in absence of oxygen. For example, yeasts in absence of oxygen convert sugar into alcohol and produces energy. This energy is then utilized for their survival.

Thus, the correct answer is option B.
