- For our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors. John takes a drug called metformin, in conjunction with regulating his diet and exercising. This drug has two main effects. First, it helps reduce hepatic (liver) production of glucose. Second, it helps cells become more sensitive to insulin. Explain how these two effects of metformin can help John.arrow_forwarda) Explain in your own words what a feedback system is.

Which of the following best describes this situation. This was a testing experiment because it happened in Pavlov's lab. This was a testing experiment because Pavlov's assistants were interacting with the dogs rather than passively observing them. This was an observational experiment because Pavlov was not testing a hypothesis when he observed this. This was not an experiment because Pavlov did not intend to make this observation. This was an observational experiment because Pavlov did not take any measurements.arrow_forward

The scaffold will have have capsules of islet beta cells which will diffuse into the pancreas to create a functional pancreas. I will use the Brunauer–Emmett–Teller (BET) technique to determine the specific surface area and porosity of the scaffold material. In the context of the TPU scaffold, the BET technique will provide crucial insights into its porosity and its potential to facilitate the infusion of beta cells into the pancreas. Can you explain the expected/ideal results from the BET test and how the test will help the design process of this medical scaffold.arrow_forward
