Concept 1:
Analyzing the Processes of Cellular Respiration.
Refer to pg 77-82 in Holtzclaw, Ch 9 in Campbell and media resources
Refer to pg 300-303 in Holtzclaw, Inv 6 in LabManual
You must know…
 The equation for cellular respiration.
 The components of a repsirometer and how they interact
 The gas laws that affect volume changes within the
repsirometer and cellular respiration
 The effect of temperature or increased metabolic activity
on respiration
 How to calculate the rate of respiration
Read lab manual and p. 300-303 in Holtz
Do #1-6 p. S73 in manual and #1-4 p. 303 in Holtz
The summary equation of cellular respiration.
The difference between fermentation and cellular
respiration.
 The role of glycolysis in oxidizing glucose to two
molecules of pyruvate
 The process that brings pyruvate from the cytosol
into the mitochondria and introduces it into the
citric acid cycle
 How the process of chemiosmosis utilizes the
electrons from NADH and FADH2 to produce ATP


C6H12O6 + 6 O2  6 CO2 + 6 H2O + Energy (ATP + heat)
Where can you find all of these reactants/products?
Glycolysis
Citric Acid Cycle
Oxidative
Phosphorylation
Glucose is the
reactant
6 CO2 are
produced for each
glucose (oxidation)
O2 is reduced to
H2O (as NADH is
oxidized back to
NAD+)

Produces NADH, FADH2 as well as some ATP
Synthesizes 90% of
the ATP by oxidizing
NADH
