The correct option is this: STORING INGESTED FOOD AND PARTIALLY DIGESTING MACRO MOLECULES.
During the digestive process, the stomach secretes acid and enzymes which digest the food in the stomach. The stomach muscles contract periodically in order to churn up the food and ensure digestion, thus turning the food to chyme. When the stomach has done its part in digestion, the chyme will be passed to the small intestines through the pyloric sphincter.<span />
<span>Tropomyosin serves as a contraction inhibitor by blocking the myosin binding sites on the actin molecules.</span>
Perhaps it is scientific inquiry?
Hope this helped! Have a great day!
