Slide1
How can we make digestion efficient?
Baseline (Flightpath D): To be able to
state that the stomach contains acid, state that the liver produces bile and write a simple hypothesis and prediction.
Further (Flightpath C&B ): To be able to
describe the functions of bile and
analyse
data in order to determine whether a hypothesis is correct.
Challenge Flightpath A):
To be able to explain how acid in the stomach increases the efficiency of pepsin, how bile increases the efficiency of fat digestion and explain how the rate of an enzyme-
catalysed
reaction shows how efficient the reaction is.Slide2

Learning objective
Further understand the how the production of bile in the gall bladder
aids digestionSlide3

Breaking down protein experiment
1/3 fill a test tube with hydrochloric acid
1/3 fill a test tube with pepsin solution
1/3 fill a test tube with a mixture of hydrochloric acid and pepsin
Add a chunk of meat to each tube.
