Which membranous organelles in a cell sequence enzyme and electron molecules for efficient cellular respiration?

• Correct Answer: bacterial
• glucose
• protons
• mitochondria

Explanation: Mitochondria, shown here as the green ovals in this animal cell, are membranous organelles which sequence enzyme and electron carrier molecules to make cellular respiration highly efficient. Mitochondria have both an inner and outer membrane, with a matrix inside the inner membrane. The inner membrane has many internal folds, increasing the surface area for proteins and molecules involved in cellular respiration.
