|
According to the sliding filament theory, how does muscle contraction occur?
|
|
Myosin heads form cross bridges and pull thin filaments, causing them to slide.
|
|
|
Both thick and thin filaments shorten as the muscle contracts.
|
|
|
A bands bunch up and shorten as myosin heads attach to thin filaments.
|
|
|
Myosin heads attach and detach from thin filaments, causing thin filaments to shorten.
|
Explanation:
Detailed explanation-1: -The sliding filament model of muscle contraction describes how muscles generate force and produce movement. Muscle contraction occurs as a result of the sliding of thin filaments (actin) over thick filaments (myosin) within muscle fibers.
