Which of the following statements is TRUE regarding lysosomes?
They are involved in protein synthesis.
They are the site of cellular respiration.
They contain hydrolytic enzymes that function optimally at an acidic pH.
They store genetic material.
Which statement regarding coenzyme is incorrect?
They are organic molecules.
They are not consumed during the reaction.
They are essential for the activity of some enzymes.
