Which of the following is true about gluconeogenesis?

BlackTom AI · Accepted Answer

The question asks which statements about gluconeogenesis are true, and it specifies selecting all that apply.
Option A: 'Amino acids can be used as a source to form glucose.' This is true. Gluconeogenesis uses non-carbohydrate substrates, including glucogenic amino acids, lactate, and glycerol, to synthesize glucose, especially during fasting or low carbohydrate intake.
Option B: 'It is the formation of glucose from carbohydrate sources.' This is incorrect. Gluconeogenesis converts non-carbohydrate precursors into glucose. Forming glucose directly from carbohydrate sources would be glycolysis or glycogenolysis contexts; gluconeogenesis specifically bypasses steps from non-carbohydrate substrates.
Option C: 'It often occurs when a person has not consumed adequate carbohydrates.' This is true. During fasting or low-carbohydrate conditions, gluconeogenesis helps maintain blood glucose levels to supply tissues that depend on glucose, such as the brain and red blood cells.
Option D: 'Gluconeogenesis happens in the gallbladder.' This is incorrect. The liver is the primary site of gluconeogenesis, with contributions from the kidneys under certain conditions; the gallbladder is not a site of this metabolic process.
In summary, Options A and C are true, while Options B and D are false due to mischaracterizations of substrates and anatomical location.
