How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately

6.1.1 Explain why digestion of large food molecules is essential. There are two reasons why the digestion of large food molecules is vital. Firstly‚ the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly‚ the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion‚ facilitated diffusion or active

role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase‚ the key enzyme for starch digestion‚ salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose‚ amylopectin‚ and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency.

Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my
