The question is incomplete: the complete question is:
Rank molecules or group of molecules by when mammals use as fuel, starting right after meal to only through?
starvation.
a) glucose from glucose-2-phosphate from glycogen.
b) free glucose and amino acids
c) fatty acids from triglycerides
d) glucose produced from amino acids in liver.
Answer:
B
A
C
D
Explanation:
Free glucose and amino acid enters into the blood stream directly and can be used immediately after meals by mammals.
The liver stores excess glucose as glycogen, hence when glucose levels begin to reduce in the body, the pancreas releases glucagon which converts glycogen to glucose.
Triglycerides are broken down to give fatty acids which gives much more energy than glucose.
During starvation, amino acids in the liver is converted to glucose when a person goes for days without eating.
You are given two beakers, distilled water, two hot plates, two thermometers and salt. These materials are enough in order to test the effect of salt in the boiling point water. To do this, you set up two beakers. In one of the beakers, you add pure distilled water and nothing else. For the other beaker, you put a solution of salt and water. You place these beakers on separate hot plates and place inside the beakers the thermometers. You heat these substances until they boil and then you measure the boiling points of the substances. You would observe that the boiling point of the solution would have a higher boiling point than the pure liquid.
N₂ + 3H₂ ⇒ 2NH₃
1mol : 2mol
3,72mol : 7,44mol
n = 7,44mol
M = 17g/mol
m = n * M = 7,44mol * 17g/mol = 126,48g
