1. food intake is : intermittent
2. is glucose requirement continouus or intermittent: continous
3. what makes the nervous cells different from other cells in the body: Most cells in the body can
burn proteins, fats, or sugars (glucose) for energy.
Except for cells in the nervous system. They can ONLY burn glucose long-term. So while these
nervous system cells need glucose constantly, you don't eat con- stantly. So we had to have a
way to store glucose until a time when we need it.
4. will there ever be a time when our bodies don't store glucose: 1.Our bodies look at glucose the
way we look at money. It wouldn't matter how much you had, if I offered you more, you'd take
it. So there will never be a time when our bodies don't store glucose.
5. where can glucose be in the body: in the blood or in the cells.
6. what is the difference between glucose in the blood or in the cells: We lower blood sugar by
moving glucose from the blood to the cells. And we raise blood sugar when we move sugar from
our cells to our blood.
7. what happens when glucose gets high in the blood: it gets assembled into a big molecules
called glycogen.

8. where is glycologen stores: in our liver and skeletal muscle.
9. what is glycogen used for: short term energy storage
10.what happens when theres no more room in our liver or skeletal muscle for glycogen: excess
glucose gets assembled into fat and stored all over our bodies
11.genesis means to " " lysis means to " ": 1.
create
2. break apart
12.what is glycogenesis: When blood sugar is high, glucose gets assembled into glycogen
13.what is glycogenolysis: When blood sugar is low, glycogen gets broken down into glucose
14.how long does it take glycogen to get used up: after a few hours of fasting
15.what happens if you cut out sugar altogehter in your diet: Your nervous system still needs
glucose.
Fats, proteins, and sugars are all made of carbon, hydrogen and oxygen.
So, making glucose from fats and proteins is all just a matter of rearranging these C, H, and O
atoms
16.what is new glucose molecules being synthesized from proteins and fats-
: gluconeogenesis
17.why does gluconeogenesis mean, where does it happen, and why does it happen: 1. making

new glucose

2. the liver
3. support the nervous system cells
18.what are biomolecules: proteins, fats, and sugars
19.where are biomolecules broken down: in the mitochondria during cellular respiration to
make ATP
20.besides making ATP what else can biomolecules be used for: spare parts to build other
proteins, fats and sugars that the cell needs
stored for energy
21.is glycogen short term or long term energy
is fat short term or long term energy: glycogen is short term energy and fat is long-term energy
22.what are the 3 things biomolecules can be used for: •Broken down to release energy
• Used to synthesize other molecules
• Converted to energy storage molecules
-Glycogen (carbohydrate)
-Triglyceride (fat)
