Final answer:
Amylin and GLP-1 both cause a decrease in gastric emptying time and gastric secretions.
Step-by-step explanation:
Amylin and GLP-1 are two hormones involved in regulating gastric emptying time and gastric secretions. Amylin primarily causes a decrease in gastric emptying time, meaning that it slows down the rate at which food leaves the stomach and enters the small intestine. It also inhibits gastric secretions, reducing the production of acid and enzymes in the stomach. On the other hand, GLP-1 (glucagon-like peptide-1) also delays gastric emptying and inhibits gastric secretions, helping to regulate digestion and nutrient absorption.
