What is an advantage of the smaller size of prokaryotes compared to eukaryotes? - Answer
higher surface area relative to low cell volume and more rapid growth rates
What biosynthetic reactions require energy for conversion of smaller units into larger
molecules? - Answer anabolic reactions
Bioremediation refers to... - Answer using bacteria to help clean up pollutants
What is true about coenzymes? - Answer they are organic molecules, transfer of atoms from
one to another, binding of different enzymes, all of the answers
What are biofilms? - Answer a polysaccharide encase community of microorganisms may
enhance bioremediation and may protect organisms against harmful chemicals

Electron transport system requires... - Answer a membrane and generates a concentration
gradient of protons
Bacillus fastidious might be expected to be... - Answer very strict in its growth requirements
and need rich media growth, have a rod shape
Substrate inhibitor bind to... - Answer active site and a sulfate antibiotic is a competitive
inhibitor
Is it a good idea to dump whey into a lake for the fish? - Answer No, the bacteria would eat up
all the oxygen
