CELLULAR RESPIRATION
• Anaerobic respiration
• a form of respiration using electron acceptors other than
oxygen.
• Aerobic respiration
• The process of generating energy by the
full oxidation of nutrients through Krebs cycle where
oxygen is the final electron acceptor.
• Fermentation
• a metabolic process converting sugar to acids, gases
and/or alcohol
• Absence of the electron transport chain.

CELLULAR RESPIRATION
•Equipment
• –Volumeter
• an instrument for measuring the volumes of gases and liquids
and of solids by the amount of gas or liquid they displace.
• –Thermobarometer
• an apparatus that provides an accurate measurement of
pressure by observation of the change in the boiling point of a
fluid
•Know
• –Phenol red turns yellow with acid
• –KOH absorbs CO2

TERMS TO KNOW
“Chrom”-- words
• Chromatin
• Relaxed chromosomes in interphase.
• Chromosome
• A structure within the cell that bears the genetic material as a
threadlike linear strand of DNA bonded to various proteins in
the nucleus of eukaryotic cells, or as a
circular strand of DNA (or RNA in some viruses) in
the cytoplasm of prokaryotes and in
the mitochondrion and chloroplast of certain eukaryotes.
• Chromatid
• Half of a duplicated chromosome (half of X shaped
duplicated chromosome). When chromatids separate they are
now called chromosomes.
