Practice question
Question
Organelle P is a membrane-bound vesicle containing hydrolytic enzymes that function best at acidic pH. Organelle Q is double-membrane-bound, has cristae and produces ATP during aerobic respiration. Which identification is correct?
Explanation
Lysosomes are membrane-bound vesicles containing hydrolytic enzymes that are optimally active at acidic pH. Mitochondria are double-membrane organelles whose inner membrane forms cristae and whose aerobic respiratory activity generates ATP.
