Which organ is responsible for releasing myocardial depressant factor that leads to heart damage as a result of multiple organ dysfunction syndrome (MODS)?

The ischemic pancreas

Explanation:

The ischemic pancreas is responsible  for the secretion of myocardial depressant factor into the blood, a small peptide which is implicated in myocardial infarction as the heart is damaged when an individual suffers from Multiple organ dysfunction syndrome. MODS involves a gradual damage and physiological dysfunction of more than two organs of the body which could include, the heart, liver, brain, kidney. When the heart is involved, myocardial depressant factor is released by the pancreas, which causes great damage to the heart.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
