Hi,

For question 128 can you please explain why option A is incorrect? What causes a greater force of contraction? How does more mitochondria impact other areas?

Hello,

All three statements are true!

Fast-twitch fibers (type 2) do contract with more force than slow-twitch (Type 1), but slow-twitch has greater endurance and require the replacement of more ATP through aerobic respiration in sustained contractions.

Option 1 does not help explain why Type 1 has a greater density of mitochondria, so C is the best answer. Mitochondria are involved in energy production. Option 3 is valid because connection btw mitochondria and energy production through aerobic respiration. option 2 is about type 2 fibers requiring more energy, however, option 1 is about type 2 fibers requiring more energy and, taken out of context would actually suggest type 2 fibers would have more mitochondria than type 1 fibers. 2 does not answer the question and is not included in the best answer.
