During a skeletal muscle contraction, the three ways in which ATP is generated are through direct phosphorylation, anaerobic pathway and aerobic respiration. In direct phosphorylation, ADP is phosphorylated by creatine phosphate; in anaerobic pathway, glycolysis and lactic acid formation occur; and in aerobic respiration, 95% of ATP is produced.
In short, the three pathways are:
- Regeneration of ATP using creatine phosphate. It breaks down lending its phosphate molecule to regenerate ATP.
- Regeneration of ATP through glycolysis, i.e. using glucose and glycogen stored in your blood and muscles.
- Regeneration of ATP using the aerobic metabolism, i.e. oxygen.
The first two are anaerobic processes while the latter is (obviously) aerobic.
1. Direct Phosphorylation of ADP by creatine phosphate.
2. Anaerobic pathway (AKA: Glycolysis)
3. Aerobic Respiration.

during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
Myosin acts with Actin during muscle contraction
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
yes skeletal muscle stretch by means of contraction.
Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).
stimulation of the muscle by a nerve ending.
It increases about to about four times greater than a normal contraction for skeletal muscle.
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
During skeletal muscle contraction myosin cross bridges attach to active sites of actin filaments. Actin filaments bind ATP. Their growth is regulated by thymosin and profilin.
The skeletal muscles do have the involuntary muscle because they help it in the contraction process.
Idk thats why im here
