Which of the following is not true regarding gluconeogenesis?
A
It requires energy from ATP
B
It generates glucose
C
It is the exact reverse of glycolysis
D
It requires energy from GTP
Verified step by step guidance1
Understand the process of gluconeogenesis: It is the metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates.
Recognize that gluconeogenesis is not simply the reverse of glycolysis. While it shares some steps with glycolysis, it involves different enzymes and bypasses certain irreversible steps of glycolysis.
Identify the energy requirements: Gluconeogenesis requires energy input, specifically from ATP and GTP, to drive the reactions forward.
Compare the statements: Evaluate each statement based on your understanding of gluconeogenesis. The statement 'It requires energy from ATP' is true, as is 'It requires energy from GTP'. 'It generates glucose' is also true.
Conclude that the statement 'It is the exact reverse of glycolysis' is not true, as gluconeogenesis involves different enzymes and pathways to bypass irreversible steps in glycolysis.
