Glucose Breakdown in Certain Mammalian and Bacterial Cells Can Occur

question 20

Multiple Choice

Glucose breakdown in certain mammalian and bacterial cells can occur by mechanisms other than classic glycolysis. In most of these, glucose 6-phosphate is oxidized to 6-phosphogluconate, which is then further metabolized by:

• A) an aldolase-type split to form glyceric acid and glyceraldehyde 3-phosphate.
• B) an aldolase-type split to form glycolic acid and erythrose 4-phosphate.
• C) conversion to 1,6-bisphosphogluconate.
• D) decarboxylation to produce keto- and aldopentoses.
• E) oxidation to a six-carbon dicarboxylic acid.
