Question

Quizplus · Accepted Answer

Titin is a protein that plays a crucial role in maintaining the structure of sarcomeres, the basic unit of muscle contraction. Without titin, sarcomeres would not be able to hold their structure and the muscle would not function properly. This would likely result in muscle weakness or inability to contract effectively, leading to various functional deficits. Therefore, choice D (sarcomeres will not hold their structure) is the most likely direct outcome of eliminating titin.
