“Respiration, Photosynthesis”
These are the diagrams taken from the Campbell test bank. They may or may not appear on your test. The questions may
be Campbell’s or my own. This worksheet is designed to put you “through the paces” before the test does. It will also help
you to define your questions so you have time to research the answers.
Ch. 9 Respiration fig.9.9, pp.166-7
Which step…
4. shows a split of one molecule into two smaller
molecules?
5. step is an inorganic phosphate added to the reactant?
6. does an intermediate pathway become oxidized?
7. involves an endergonic reaction?
8. consists of a phosphorylation reaction in which ATP is the phosphate source?
9.
Starting with one molecule of isocitrate fig.9.12, p.169 
and ending with fumarate, what is the
maximum number of ATP molecules
that could be made through substratelevel phosphorylation?
10. How many molecules of carbon dioxide
(CO2) would be produced by five turns
of the citric acid cycle?
11. Carbon skeletons for amino acid
biosynthesis are supplied by intermediates
of the citric acid cycle. Which intermediate
would supply the carbon skeleton for
synthesis of a five-carbon amino acid?

Citrate

Isocitrate

-Ketoglutarate

Succinate

Malate.
12. How many reduced dinucleotides would be produced by four turns of the citric acid cycle?
___ FADH2 and ___ NADH.
13. Starting with citrate, how many of the following would be produced with three turns of the citric acid cycle?
