Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.
Answer:
As 2020 continues, it has become increasingly easy to believe that the institutions of American democracy are breaking down. The president of the United States, despite having lost the presidential election, refuses to concede. Congress, which currently boasts a 21% job approval rating, has consistently demonstrated an inability to pass legislation supported by a majority of Americans. A third of the Supreme Court, an institution with tremendous power over American civil rights, consists of appointees by a president who lost the popular vote.
The enteric division of the ANS is found in the gastrointestinal tract of the body.
Here ANS stands for the autonomic nervous system which can be described as a collection of motor neurons that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.
It has three divisions: sympathetic, parasympathetic, and enteric.
Out of three, the enteric division has two plexuses: the myenteric (Auerbach) which is usually detected in the GI tract, and the submucosal (Meissner) which is usually observed in the submucosa.
The sympathetic division is located in intermediolateral columns, or lateral horns, of the spinal cord whereas the parasympathetic division is located in the head.
