Bile is the substance secreted by the gall bladder to aid the break down of fats into an emulsion. Bile is not an enzyme. It only causes the fat to emulsify. In this experiment, you will use soap to break up the oil.
In this experiment, you will observe the emulsification of fat in milk. This is a model of how bile emulsifies fat in your digestive system. The soap is used in place of bile.

Submit your observations.
Give an explanation of what is happening in this experiment.

What do you think would happen if this experiment was conducted with skim milk? Explain your response.

What do you think would happen if this experiment was conducted with cream? Explain your response.

What do you think would happen if this experiment was conducted with water? Explain your response.

Mike has a problem with his testosterone. he is unable to produce enough. which will most likely be affected by his inability to produce testosterone? check all that apply.

Prior knowledge can be gained from personal experience and a) forming well-developed hypotheses. b) listening to opinions of other people on a topic. c) researching previous experiments and results on a topic. eliminate d) no other methods. it can only be gained by personal experience.

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
