Ryan has sprained his ankle for the fifth time in the last few years. He believes he is now more prone to spraining it than he used to be. It also takes several weeks for it to feel better, unlike Grace, who twisted her ankle last weekend, but it feels better already. Explain what may be going on here on a molecular level, using the following questions as guidelines: Why does it often take longer for a sprain to heal than it does simple breaks? Propose a molecular reason that might explain why Ryan sprains his ankle more often now than he used to. 3. What sort of treatment do you think Grace may have used to speed up her healing? On a molecular level, how would this help?
