Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
T/F-The sliding filament Theory, states that the actin and myosin filaments slide past each other. This sliding actually occurs from a ratcheting mechanism of these filaments.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -By studying sarcomeres, the basic unit controlling changes in muscle length, scientists proposed the sliding filament theory to explain the molecular mechanisms behind muscle contraction. Within the sarcomere, myosin slides along actin to contract the muscle fiber in a process that requires ATP.
