Title: PhysioEx 9.0 Activity 8 Post by: Leah2010 on Nov 7, 2012 Hi I just need a few answers to these questions from PhysioEx 9.0
:o :o Was your prediction correct about the optimal pH for pepsin activity? Discuss the physiological correlation behind your results. What do you think would happen if you reduced the incubation time to 30 minutes for tube 5? Describe the process of bile emulsification of lipids and how it improves lipase activity. Thanks in advance! ;D Title: Re: PhysioEx 9.0 Activity 8 Post by: bio_man on Nov 7, 2012 Was your prediction correct about the optimal pH for pepsin activity? Discuss the physiological correlation behind your results. The correct prediction is pH 2.0. This is because pepsin is most active at the pH of gastric juice which is about pH 2.0. Title: Re: PhysioEx 9.0 Activity 8 Post by: bio_man on Nov 7, 2012 What do you think would happen if you reduced the incubation time to 30 minutes for tube 5? If the incubation time were reduced, it is possible that no digestion of protein would be seen since only a small amount is seen.

Bile serves to mechanically break up large globules of fat and produce small droplets that effectly increases the surface area of the lipids.
