MCQ on Proton Gradient and ATP Synthesis
A proton gradient is a difference in proton concentration across a membrane, created by the electron transport chain. ATP synthesis occurs when protons flow back […]
MCQ on Chemiosmotic Coupling Mechanism of ATP Synthesis
Chemiosmotic coupling is the mechanism by which ATP is synthesized in mitochondria and chloroplasts. It involves the movement of protons across a membrane, creating a […]
MCQ on Q Cycle
The Q cycle is a mechanism in the electron transport chain’s complex III (cytochrome bc1 complex) that transfers electrons from ubiquinol (QH2) to cytochrome c. […]
MCQ on Reduced Coenzymes
Reduced coenzymes, such as NADH and FADH2, are molecules that carry electrons and hydrogen ions during cellular respiration. They are formed when NAD+ and FAD […]
MCQ on Link Reaction (Pyruvate Decarboxylation)
The link reaction, or pyruvate decarboxylation, is the process where pyruvate from glycolysis is converted into acetyl-CoA in the mitochondria. Pyruvate loses a carbon dioxide […]
MCQ on Electron Transport System for NEET 2024
