Worksheet - Cell Respiration
CELLULAR RESPIRATION
 Aerobic & Anaerobic
1. The function of cell respiration is to provide cells with __________________
2. The most common food substance from which cells obtain energy is the
monosaccharide known as ________________, which has the molecular
formula _________________
3. The difference between aerobic & anaerobic respiration is that aerobic
respiration requires the presence of __________________ while anaerobic
respiration does not. Also, MORE energy is produced from
____________________ respiration.
4. The cell’s usable form of energy is a chemical compound called adenosine
triphosphate, abbreviated ___________. This compound is considered a
HIGH-ENERGY compound because it enables our cells to efficiently carry out
their life processes (functions).
5. In aerobic cell respiration, ______ molecules of ATP are produced for every 1
molecule of glucose oxidized (broken down). In anaerobic cell respiration, only
______ molecules of ATP are produced (per 1 molecule of glucose).
6. Glycolysis is the conversion of 1 molecule of glucose into 2 molecules of
__________________ (aka pyruvic acid). Glycolysis occurs in the
__________________ of cells and produces a net total of ______ ATP.
For our purposes, we will examine 3 possible “fates” of pyruvate:
 BACTERIA – turn pyruvate into ______________ ______________during an
anaerobic process known as lactic acid fermentation
 YEAST – usually turn pyruvate into ethyl alcohol (ethanol) AND _______ during
an anaerobic process known as alcohol fermentation
 HUMANS – normally turn pyruvate into _______________ _______, which
then enters the Krebs cycle & ETC (of the MITOCHONDRIA) to produce CO2
(waste), H2O & 34 ATP. Overall, these processes are referred to as aerobic
respiration because __________________ is required in the process.
