1) During the starvation state, what is the brain’s primary food source (glucose or fat) and is this considered dangerous for our bodies?
How to answer this:
The answer to this question is that GLYCOGEN reserves (which originate from glucose) and which are located in your liver and muscle will be your first source, but after a long period of starvation, the body will start using the fat reserves (i.e., triglycerides) located in the adipose tissue.
With this information, you should therefore explain how from triglycerides we can get energy (i.e. ATP).
Remember what triglycerides are made of. What happens to each of the molecules that make up triglycerides (i.e. glycerol and fatty acids)?
If your reasoning is correct, your answer should lead to ketone body production and an explanation of the 3 types of ketone bodies. Can ketone bodies be used by the brain?
To answer the part “Is this dangerous for our bodies?”, you should explain what happens if we have too many ketone bodies circulating in the body. Remember, it’s important to explain how from triglycerides we can get ATP.
2)What are the protein needs for? Also discuss why protein supplements may or may not be beneficial.
A) a person with chronic renal failure and not on dialysis
B) an overweight/ obese adult
C) a professional weight lifter
how to answer:
-In order to answer this question, you will need to tell me first the RDA for a normal individual, and from there let me know what A), B) and C) require in terms of protein.
-Do they need more or less than the normal average individual and **why**? If you can provide an actual requirement value for A), B) and C) that would be great.
-Also, in the case of A) why the distinction of *not on dialysis*? Would the protein needs differ if the patient was on dialysis?
-Also, let me know if protein supplements are beneficial or harmful for the average Joe, i.e. for the average individual, and why.
