What role do hormones play in enzyme secretion control?
Click to flip
Hormones like gastrin, secretin, and cholecystokinin regulate enzyme secretion in the digestive tract.
Click to flip
How does the nervous system influence enzyme secretion?
Click to flip
The nervous system modulates enzyme secretion via the enteric nervous system and through autonomic (sympathetic/parasympathetic) pathways.
Click to flip
What is the role of the pancreas in enzyme secretion?
Click to flip
The pancreas secretes digestive enzymes like amylase, lipase, and proteases into the small intestine.
Click to flip
How does feedback inhibition regulate enzyme secretion?
Click to flip
Feedback inhibition involves the end product of a metabolic pathway inhibiting an earlier process to decrease enzyme production.
Click to flip
What are zymogens and their significance in enzyme secretion?
Click to flip
Zymogens are inactive enzyme precursors that prevent damage to tissues and are activated in the digestive tract.
Click to flip
What triggers the secretion of enzymes in the stomach?
Click to flip
Enzyme secretion in the stomach is triggered by food presence, hormone gastrin, and autonomic nervous system signals.
Click to flip
Describe the role of cholecystokinin in enzyme secretion.
Click to flip
Cholecystokinin stimulates the pancreas to release digestive enzymes and the gallbladder to secrete bile.
Click to flip
How does pH affect enzyme secretion and activity?
Click to flip
Each enzyme has an optimal pH; deviations can inhibit enzyme activity or secretion due to denaturation.
Click to flip
What is the impact of diet on enzyme secretion?
Click to flip
Diet influences enzyme secretion by triggering production based on the type of nutrients consumed.
Click to flip
Can stress affect enzyme secretion? How?
Click to flip
Yes, stress affects enzyme secretion by impacting the autonomic nervous system, possibly reducing digestive efficiency.
Click to flip
How is enzyme secretion in newborns different from adults?
Click to flip
Newborns have limited enzyme secretion capabilities and rely heavily on breast milk or formula for nutrients.
Click to flip
What feedback mechanism inhibits gastric secretions when digestion is complete?
Click to flip
When digestion is complete, low pH and absence of food inhibit gastrin, reducing gastric secretions.
Click to flip
How does the liver contribute to enzyme regulation?
Click to flip
The liver secretes bile, aiding in fat digestion, and detoxifies substances affecting enzyme activity.
Click to flip
What happens if enzyme secretion is impaired?
Click to flip
Impaired enzyme secretion leads to digestion issues, malabsorption, and nutrient deficiencies.
Click to flip
What is the main control center in the brain for regulating enzyme secretion?
Click to flip
The hypothalamus is the primary brain center involved in regulating enzyme secretion via autonomic pathways.
