, 1. The purpose of the Krebs cycle is to produce high energy carrier molecules like NADH and FADH2 that
then feed into the electron transport chain. During this process, another by-product molecule is
produced. Which molecule is produced during the Krebs cycle? Hint: the Krebs cycle is part of aerobic
respiration.
a. water
b. carbon dioxide
c. lipids
d. glucose
One of the end products of glycolysis is:
fructose
glucose
carbon dioxide
pyruvate
The purpose of glycolysis and the Krebs cycle is to use split glucose to harness the energy in the bonds thereby
generating high energy molecules that feed electrons into the electron transport chain. If an organisms has a
defect in an electron chain molecule but can complete glycolysis, would the organism be able to survive?
No, the organism would not be able to produce any energy.
, No, the organism would not be able to control the large amount of energy produced.
Yes, although the organism may be limited in size because only a small amount of energy is produced.
Yes, although the organism would not have any way of controlling the large amount of energy produced.
