For each question, you’ll be given one of the standard human muscle types, then one functional difference the new muscle you’re designing must have.  You indicate one structural difference between the standard and the new type that will create the desired feature in the new type. For example, if the question was “Gut smooth muscle, but more red” an answer would be “more myoglobin”. Sometimes multiple answers are possible; you need to give only one unless told otherwise.

1.          Cardiac muscle, but its rate never Designer Muscles.

2.          Skeletal muscle, but always does synchronous recruitment; never asynchronous.

3.          Skeletal muscle, but better at exerting force when very stretched.

4.          Slow twitch skeletal muscle, but more powerful.

5.          Smooth muscle, but can not experience tetany.

6.          Smooth muscle, but more powerful. Choose a feature that is notinvolved with ATP production.

7.          Smooth muscle, but better at bringing in oxygen and having it available at all times.
