Combines with fatty acids to make lipids.

5.
A substance that slows down or stops a chemical reaction

6.
a lipid made of three fatty acid molecules and one glycerol molecule

7.
A specific reactant acted upon by an enzyme

8.
A simple sugar that is an important source of energy.

9.
A type of protein that speeds up a chemical reaction in a living thing (a biological catalyst)

10.
A substance that reduces the activity of an enzyme by entering the active site in place of the substrate whose structure it mimics.

11.
bacteria in the root nodules of legumes or free living in the soil that convert atmospheric nitrogen into ammonia

12.
The transfer of nitrogen from the atmosphere to the soil (nitrogen fixation), to living organisms, and back to the atmosphere (denitrification).

13.
'water-fearing'; nonpolar molecules (or parts of molecules) that do not dissolve in water.

14.
hydrocarbon chain often bonded to glycerol in a lipid

15.
Bacteria that convert the nitrates in soil or water to gaseous nitrogen and release it back into the atmosphere.

16.
a nitrogen-containing base found in RNA (but not in DNA) which bonds with adenine

17.
a region on an enzyme that binds to a protein or other substance during a reaction.

18.
the process by which one or more substances change to produce one or more different substances

19.
a lipid that contains phosphorus and that is a structural component in cell membranes

20.
a single ringed nitrogen base that bonds with the nucleotide adenine in DNA.

24.
Carbon is one of the chemical elements found in nature, it is one of the most common elements in living things.

25.
The series of processes by which carbon compounds are cycled in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
