Problem:
A gastrocnemis muscle at its optimal length, when maximally stimulated by a single electrical stimulus, produces an isometric twitch tension of 80kg, and consumes 5 joules of energy above its basal energy consumption (measured by a calorimeter - includes all the energy used by the muscle as a result of that stimulus). If you then stretch the muscle (hyper-extend it) so that the same maximal electrical stimulus produces no twitch tension at all, stimulating the muscle raises its energy consumption by only 1 Joule above its basal energy consumption (measured again with the calorimeter).
Required:
Question 1: The 5 joules of energy consumed by the muscle during a maximal stimulus at optimal length were used for what? be specific.
Question 2: The 1 joule of energy consumed by the muscle during maximal stimulus at hyper-extended length was used for what? be specific.
Question 3: Explain the difference in amplitude of the twitch tnesion between optimal length and hyper-extended length. be specific.
I'm not even sure where to start with this !!!!
Does anyone know how to go about this search to explain it.
