A pathogenic microbe is? Correct Answer Disease causing?
A summary of respiration Correct Answer Aerobic- 38 ATP,
final electron acceptor in transport chain is O2 (carb
breakdown). Anaerobic-final electron acceptor in transport chain
is not O2 (glycolysis), yields less energy than aerobic
respiration.
Acid fast cell walls Correct Answer Is atypical. Similar to gram
+ cells walls, waxy lipid (mycolic acid) bound to peptidoglycan.
Acid fast stain? Correct Answer They contain mycolic acids a
waxy substance in their cell walls the waxy substance is not
decolorized by acid alcohol. They are important pathogens like
leprosy and TB.

carbolfuchsin, decolorizer-acid alcohol, counterstain-methylene
blue.
Active transport? Correct Answer Requires a transporter
protein and ATP. Can go against gradient.

Catabolism? Correct Answer Breakdown of complex organic
compounds into simple ones (AB-->A+B), generally hydrolysis
which use water to break chemical bonds, release ATP. provide
energy for anabolic reactions.
