NEET Zoology Muscle Contraction MCQ Question
In a sarcomere, if the distance between two successive 'Z' lines is reduced by 0.5 micrometers during muscle contraction, what is the new length of the sarcomere if the original length was 2.5 micrometers?
2.0 micrometers
2.2 micrometers
1.8 micrometers
2.5 micrometers
Correct Answer
Detailed Explanation
