Q1 · Glycolysis
NEET PGEasyGlycolysis occurs in which part of the cell?
Explanation
Glycolysis takes place in the cytoplasm and does not require oxygen. It converts glucose to pyruvate with a net yield of 2 ATP and 2 NADH per glucose molecule.

Q2 · Citric Acid Cycle
NEET PGMediumThe citric acid (Krebs) cycle occurs in which cellular location?
Explanation
The citric acid cycle occurs in the mitochondrial matrix. Each turn generates 3 NADH, 1 FADH2 and 1 GTP, feeding electrons into the electron transport chain for ATP production.
Q3 · Gluconeogenesis
MediumWhich organ is the primary site of gluconeogenesis during fasting?
Explanation
The liver is the main site of gluconeogenesis, producing glucose from lactate, glycerol and amino acids to maintain blood glucose during fasting. The kidney contributes during prolonged starvation.
Q4 · Pentose Phosphate Pathway
HardThe main products of the hexose monophosphate (pentose phosphate) pathway are NADPH and?
Explanation
The HMP shunt produces NADPH, for reductive biosynthesis and antioxidant defence, and ribose-5-phosphate for nucleotide synthesis. It does not generate ATP directly.
Q5 · Cori Cycle
MediumIn the Cori cycle, lactate produced by exercising muscle is converted back to glucose in the?
Explanation
In the Cori cycle, muscle lactate travels to the liver, where it is converted back to glucose via gluconeogenesis and returned to muscle. This recycles lactate and supports glucose supply during exercise.
Q6 · Electron Transport Chain
HardThe final electron acceptor in the electron transport chain is?
Explanation
Molecular oxygen is the final electron acceptor at complex IV, being reduced to water. This maintains electron flow and the proton gradient that drives ATP synthesis; without oxygen the chain halts.
Q7 · Glucose Transporters
EasyWhich glucose transporter is insulin-dependent and found in muscle and adipose tissue?
Explanation
GLUT4 is the insulin-responsive transporter in skeletal muscle and adipose tissue, and insulin promotes its translocation to the cell membrane. GLUT2 is in liver and pancreatic beta cells, and GLUT5 transports fructose.
Carbohydrate Metabolism MCQs for NEET PG & INI-CET
Carbohydrate Metabolism sits within Biochemistry, which carries the same syllabus in both exams. This set runs to 7 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 2 drawn from previous-year papers.
How to practise Carbohydrate Metabolism for NEET PG and INI-CET
Answer first, then read the explanation even on the ones you got right — the reasoning is where Carbohydrate Metabolism marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Biochemistry examiners keep returning to.
