When glucose is used for energy, the first sequence of steps are
the following. Are the steps in the correct order? A) yes B) no

phosphorylation of glucose to glucose-6-phosphate, rearrangement
glucose-6-phosphate to fructose-6-phosphate, phosphorylation of
fructose-6-phosphate to form fructose-1,6-biphosphate, splitting of
fructose-1,6-biphosphate into two phosphoylated 3-carbon sugars,
rearrangement and oxidation of 3-carbon sugars to form pyruvic
acid

The above steps describe A)the Krebs cycle B)the electron
transport system C)glycolysis D)gluconeogenesis E)glycogenesis

The above takes place A)only if oxygen is present B)only if
oxygen is absent C)whether or not oxygen is present

Which of the following is true about glycolysis? A)the first
step requires hydrolysis of ATP to ADP B)two molecules are produced
per glucose, each with half the number of carbon atoms as glucose
C)a net increase of ATP is produced without participation of the
electron transport system D)a small amount of NADH is produced
E)all of the above are true

Which of the following is not true about the Krebs cycle?
A)generates more NADH than glycolysis B)results in less ATP
thanglycolysis C)occurs when oxygen is plentifuul D)takes place in
the mitochondrion E)cyles twice per glucose molecule
