Identify the number of not incorrect statements based on the diagram shown below: The process continues till the Ca++ ions are pumped back to the sarcoplasmic cisternae During contraction, the Z-line returns to their original position. Repeated activation of the muscles can lead to the accumulation of lactic acid

Step-by-step solution

The process continues till the Ca++ ions are pumped back to the sarcoplasmic cisternae resulting in the masking of actin filaments. This causes the return of ‘Z’ lines back to their original position, i.e., relaxation. The reaction time of the fibres can vary in different muscles. Repeated activation of the muscles can lead to the accumulation of lactic acid due to anaerobic breakdown of glycogen in them, causing fatigue. Muscle contains a red coloured oxygen storing pigment called myoglobin. Myoglobin content is h
