Exam 13: The Citric Acid Cycle

True statements about the glyoxylate cycle include

Which carbon atoms) of pyruvate isare) first converted to carbon dioxide by pyruvate dehydrogenase complex?

In eukaryotes the enzymes of the citric acid cycle are found in the .

The glyoxylate cycle is

Which statement is false about the glyoxylate cycle?

Pyruvate dehydrogenase kinase catalyzes

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) $\mathrm{NAD}^{+}$ -Isocitrate dehydrogenase

Citric acid cycle components are dissolved in the cytosol for all prokaryotic and eukaryotic species.

Which of the following allosterically activates mammalian isocitrate dehydrogenase?

Which statement is true about lactate dehydrogenase and malate dehydrogenase?

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) $\mathrm{NAD}^{+}$ -Succinate dehydrogenase complex

The recycling of NAD allows glycolysis to continue in the absence of oxygen.

The succinate dehydrogenase complex catalyzes

Compounds like succinate, fumarate and α-ketoglutarate have a catalytic effect on the consumption of oxygen in a cell suspension. The rate of oxygen consumption is far more than that required for their own oxidation. This is evidence that .

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) $\mathrm{NAD}^{+}$ -a-ketoglutarate dehydrogenase complex
