Secretin increases the flow of bicarbonate ions from the pancreas into the small intestine to neutralize stomach acid.
Gastric acid regulation, pancreatic bicarbonate modulation, and osmoregulation are the three primary roles of secretin. Pancreatic fluid stimulation and bicarbonate secretion are two of secretin's main physiological effects.
Peptide hormones released by endocrine cells in the digestive system include secretin and CCK. While CCK enhances the synthesis and secretion of bile juice and pancreatic enzymes, Secretin stimulates the release of water and bicarbonate ions from the pancreas.
A pancreatic fluid that is high in bicarbonate is secreted when secretin is present. By interacting with pancreatic ductal cells, secretin enters the bloodstream or intestinal lumen and increases the production of bicarbonate, which lowers the pH of the gastric chyme as it enters the small intestine.

Answer:
Anaerobic respiration refers to the break down of food (sugar) in absence of oxygen in order to produce energy (ATP or adenosine triphosphate).
In yeast, alcoholic fermentation takes place by which glucose is converted into ethanol (alcohol), carbon dioxide (CO₂), and energy (ATP). It helps in regeneration of NAD⁺ lost during glycolysis. No electron transport chain is required in this process.
The overall reaction can be written as:
Glucose → Pyruvate → Ethanol + Carbon dioxide + ATP.
Contrary, in anaerobic bacteria respiration takes place by using electron acceptor other than oxygen such as sulfate, nitrate, sulfur, fumarate etc. Hence, electrons are passed through a electron transport chain which are finally accepted by any molecule other than oxygen.
Other molecules have less oxidizing potential as compared to the oxygen and thus less energy is released per oxidizing molecule. It makes the anaerobic respiration less efficient as compared to the aerobic respiration.
Examples of anaerobic microbes are methanogens (<em>Methanosarcina barkeri </em>uses CO₂ as final electron acceptor), Desulfuromonadales (uses sulfur as final electron acceptor) etc.
