Exam 13: The Citric Acid Cycle

The a-ketoglutarate and succinate dehydrogenase complexes are the only oligomeric enzymes used in the citric acid cycle.

Which step in the citric acid cycle is a rearrangement reaction?

During catalysis, succinyl CoA synthetase generates

When energy-rich acetyl CoA is oxidized to carbon dioxide, eight electrons are released. Most often, electrons are released in such reactions because

Pyruvate translocase is a/an protein that transports .

The following enzymes) is/are unique to the glyoxylate cycle.

The only reaction in the citric acid cycle to generate a carbon-carbon bond is catalyzed by citrate synthase.

Which is not a component of the pyruvate dehydrogenase complex?

Malonate

ATP is consumed by the pyruvate dehydrogenase complex during the synthesis of acetyl CoA.

A racemic mixture of the enantiomeric forms of isocitrate is produced during the citric acid cycle reactions.

The glyoxylate cycle leads from two carbon compounds to glucose in each organism below except

A deficiency in thiamine causes the disease beriberi. Which might you expect to have a higher than normal blood concentration in an individual with this condition?

Please match the following reactions to their respective energy yielding products. Please note that a product may be used once, more than once, or not at all as an answer. A) $\mathrm{NADH}$ B) ADP C) GTP or ATP D) $\mathrm{NADH}$ E) $\mathrm{QH}_{2}$ F) $\mathrm{NAD}^{+}$ -Malate dehydrogenase

The step at which acetyl CoA enters the citric acid cycle is classified as a reaction.

Which of the following is not a fate of a citric acid cycle intermediate?

Which of the following enzymatic reactions is not an example of substrate level phosphorylation?

Which enzyme catalyzes the conversion of citrate to isocitrate?

The mechanism of pyruvate dehydrogenase complex is an example of channeling.

In aerobic prokaryotes, the succinate dehydrogenase complex is embedded in the inner mitochondrial membrane.
