Which of the following step during sliding Filament Theory is the last step before a relaxing state?
1. ATP utilization
2. Release of ADP and inorganic phosphate
3. Cross bridge formation
4. Binding of calcium with troponin
Which of the following statements is incorrect?
1. A new ATP binds and cross-bridge is broken with the next cycle of contraction
2. The process of contraction continues till the calcium ions are pumped back to the sarcoplasmic cisternae and resulting in the unmasking of actin Filaments
3. The reaction time of the fibres can vary in different muscles
4. Both 1 and 3
Repeated activation of the muscles can lead to
1. Accumulation of pyruvate due to anaerobic breakdown of glycogen
2. Accumulation of lactic acid due to anaerobic breakdown of glycogen
3. Fatigue
4. Both 2 and 3
Which of the following property cannot be attributed to white fibers?
1. Fewer mitochondria
2. Anaerobic process for energy
3. Sarcoplasmic reticulum is high
4. More quantity of myoglobin
