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.
