Gluconeogenesis is just a reversal of glycolysis.

• True

• False

Which of the following are precursors for gluconeogenesis?

• glycerol (from fatty acids)

• glucogenic amino acids

• pyruvate

• lactate

What two organs can carry out gluconeogenesis?

• spleen and kidney

• liver and kidney

• pancreas and liver

• stomach and heart

Glucogenic AA and lactate can come from which tissue?

• muscle

• liver

• fatty acids

• red blood cells

What cells does glycolysis occur in?

• liver only

• liver and kidney only

• red blood cells only

• all cells

Gluconeogensis is not thermodynamically favorable.

• True

• False

Answer explanation

both glycolysis and gluconeogenesis are thermodynamically favorable.

The end product of one is the starting product of the other (glycolysis and gluconeogenesis).

• True

• False

Is ATP generated in gluconeogenesis?

• Yes

• No
