Final answer:
The false statement is C) Chief cells release enzymes that break down protein into fatty acids. Instead, chief cells release enzymes like pepsinogen which breaks down proteins into peptides, not fatty acids.
Step-by-step explanation:
The statement "All of the following statements are true EXCEPT: A) Gastric juices and enzymes in the stomach turn the food into a watery liquid called chyme. B) Mucoid cells secrete mucus to protect the lining of the stomach. C) Chief cells release enzymes that break down protein into fatty acids. D) Parietal cells produce hydrochloric acid to aid in chemical digestion in the stomach." requires us to identify the false statement. The correct answer is C). Chief cells release enzymes, such as pepsinogen, which is converted into pepsin to break down proteins into smaller peptides, not fatty acids. The other statements are accurate, as peristalsis mixes the food with gastric juices to form chyme, mucoid cells protect the stomach lining with mucus, and parietal cells secrete hydrochloric acid to aid in digestion.
