They were incorporated into organic molecules by plants. They
were processed into sugars through photosynthesis.
They are ultimately
derived from carbon dioxide.

It is negatively charged.
It has acid
properties.

the study of carbon compounds.
38)
the replacement of the hydroxyl of a carboxyl group with hydrogen
40)
glucose
42)
Dehydration reactions assemble polymers, and hydrolysis breaks down
polymers.
44)
polysaccharide.
46)
They are insoluble in water.
They are an important
constituent of cell membranes.
They contain twice as
much energy as an equivalent weight of polysaccharide.
48)
have a higher ratio of hydrogen to carbon than do unsaturated fatty acids.
50)
unsaturated fatty acid.

--> RNA --> proteins
66)
contains one less oxygen atom.
68)
the reaction of a fat, forming glycerol and fatty acids with the
utilization of water
70)
catabolism
72)
ATP serves as a main energy shuttle inside cells.
ATP drives endergonic
reactions in the cell by the enzymatic transfer of the phosphate group to
specific reactants.
The regeneration of
ATP from ADP and phosphate is an endergonic reaction.
74)
lowering the energy of activation of a reaction.
76)
curve 4
78)
Enzymes
may require a nonprotein cofactor or ion for catalysis to take place.
Enzyme
function is reduced if the three-dimensional structure or conformation of an
enzyme is altered.
Enzyme
function is influenced by physical and chemical environmental factors such as pH
and temperature.
Enzymes
increase the rate of chemical reaction by lowering activation energy barriers.
80)
their enzymes have high optimal temperatures.
