What are the three electron carrier molecules, which are derived from vitamins?
Involves the transfer of phosphate to ADP from another phosphorylated organic compound.
Energy from redox reactions of respiration is used to attach inorganic phosphate to ADP.
Light energy is used to phosphorylate ADP with inorganic phosphate.
Name the four carrier molecules:
carrier is Oxygen if organism can tolerate oxygen

Why are photosynthetic bacteria normally not pathogenic?
they build their own food
chloroplast --> thylakoids --> chlorophyll
just need to know the structure

A(n) ________ is composed of cells that arise from a single colony.
The ________ of an enzyme is reached when all active sites have bound substrate molecules.
Use of an organic molecule as a final electron acceptor is apart of what metabolic process?
know the structure of the enzyme
This type of inhibitor prevents the ability of an enzymes normal substrate to bind.

and causes wholes in the cheese. Cheddar has a different bacteria.
possible short answer
Why does a fish market smell "fishy"?
Some bacteria use the waste product of fish metabolism called TMAO as the final electron receptor in anaerobic respiration producing TMA which, gives off the fishy smell.
