Would you expect to find more keratin in keratinocytes closer to the external surface of the skin (more superficial) or further from the external surface of the skin (deeper)?

• A. Deeper, because it's more important that the skin is water-resistant in deeper areas.
• B. More superficial because skin on the external surface needs to be tougher and more resistant.
• C. Neither, all keratinocytes have approximately the same amount of keratin.
