Muscle contraction involves the breakdown of cross-bridges of active myosin filaments due to the following process.
- A
ATP is oxidized
- B
ATP is reduced
- C
ATP is hydrolyzed
- D
ATP is synthesized
Hydrolysis of ATP occurs during the breakdown of cross-bridges in a myofibril.
ATP is not oxidized during cross-bridge breakdown. Hence, this option is incorrect.
ATP is not reduced during cross-bridge breakdown, so the option is incorrect.
Hydrolysis of ATP causes cross-bridge breakdown and ultimately, muscle contraction. This option is the correct option.
ATP is not synthesized when a cross-bridge breaks down, so the option is incorrect.
