Are Sarcomeres made of amino acids?

A titin mutation that occurs in muscular dystrophy with myositis (mdm) mice results in a predicted 83 amino acid deletion in the N2A and PEVK regions of the titin protein. Muscles from mdm mice are actively more compliant  possibly owing to the deletion in titin's I-band region. This suggests that modulation of titin stiffness in active sarcomeres by the proposed titin–thin filament interaction may be affected by the mdm mutation. The answer is YES I believe.

Explanation:

I believe the answer is yes from my deep reaserch. You may want to research in your texts book/lesson or courses and review what your teacher/professer has given you.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
