Sorry but. Do your own school!
A testable question is something you need data for, ex: if i bounce a bouncy ball from larger heights, how high will it fly? it can't be just a regular yes or no question
Am certain that Creatine phosphate functions in the muscle by storing energy that will be transferred to ADP to resynthesize ATP. All muscle cells have a little ATP within them that they can use immediately, however, only enough to last for about 3 seconds. Therefore, all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly.

DNA always forms proteins
