What does pH measure Physioex exercise 8 Activity 4?

What does the pH measure? You correctly answered: both lipase activity and fatty acid release.

Which pH is ideal for pancreatic lipase?

One of the many enzymes pancreatic juice contains is lipase. As a result of the alkalinity of the bile salts, the pH of the duodenum is approximately 7.0, which is also the optimum pH for pancreatic lipase.

What does the pH measure lipase activity?

The pancreatic lipase enzyme has the highest enzymatic activity in environment around pH 7. The oral cavity has pH around 7 and the small intestine around 8 so the enzyme would work in both places. Describe the process of bile emulsification of lipids and how it improves lipase activity.

Which tube had the highest lipase activity How well did the results compare?

The correct prediction is tube #1, pH 7.0, which approximates the pH of the small intestine. Since the activity of pancreatic lipase is highest at pH 7.0, the enzyme should be active in the mouth and the pancreas.

At what pH was amylase most active?

You correctly answered: amylase activity was highest at pH 7.

Where in the body does pancreatic hydrolyze triglycerides?

Hydrolysis starts in the stomach where, in humans, gastric lipase cleaves 15–20% of the fatty acids and goes to completion in the upper small intestine where the emulsion mixes with pancreatic juice containing several lipases capable of hydrolyzing triglycerides (3, 4).

What temperature does lipase work best at?

37°C
The optimal temperature for the lipase activity of LipL was demonstrated to be 37°C, and the optimal pH was 8.0.

Is lipase in the stomach?

In humans, lipase is present in the serous (von Ebner) glands of the tongue, where it is localized in zymogen granules. In the stomach, the highest lipase activity is in the body. By immunocytochemistry, gastric lipase is confined to the chief cells of the fundic mucosa and is colocalized with pepsin.

Why would pancreatic lipase be active in the mouth?

Explain why pancreatic lipase would be active in both the mouth and the pancreas. Your answer: The pancreatic lipase enzyme has the highest enzymatic activity in environment around pH 7. The oral cavity has pH around 7 and the small intestine around 8 so the enzyme would work in both places.

What happens to your results when you reduce incubation time to 30 minutes?

With more enzyme activity the optical density increases. If I reduced the incubation time to 30 minutes for tube 5, optical density would likely decrease or be 0.00. Time allows for more enzyme activity.

Which pH resulted in maximum lipase activity?

pH 8.2
Result: The highest lipase activity was found under 37 degrees C, pH 8.2, and the highest amylase activity was detected under 37 degrees C, pH 5.2, while protease activity peaked at 42 degrees C, pH 3.2 or pH 9.2. Conclusion: The optimal temperature in alimentary tract of Wh.
