1
Q
What kind of bonds do polysaccharides have?
A
Glycosidic
2
Q
What is the second law of thermodynamics?
A
The overall entropy of the universe is increasing
3
Q
what are polymers?
A
long chains of monomers assembled through dehydration reactions.
4
Q
how do lipids create more lipids?
A
vesicles increase in size until they become unstable and then they split into two
5
Q
what are lipids
A
ester linkage between glycerol attached to acyl chains
6
Q
why is glycogen more heavily branched than starch?
A
So it can be densely packed into a cell to meet storage constraints and reduce osmotic stress on the cell
7
Q
what bonds are present in glycogen and cellulose
A
Glycogen has alpha- 1,4 and alpha- 1,6 (branches)
Cellulose has beta-1,4
8
Q
what is ATP
A
