When Sarcomeres Contract, They Generate Force (Tension)

question 1

Multiple Choice

When sarcomeres contract, they generate force (tension) . However, the amount of force generated depends on the sarcomere length and the amount of thick and thin filament overlap. Below is a figure that details the force-generating properties of a single sarcomere. This figure was modified from a scientific paper by Al Gordon and colleagues from 1966 and is a classic illustration of the relationship between sarcomere length and force.
-At what point on the graph is the sarcomere the most extended?

• A) point A
• B) point B
• C) point C
• D) point E
