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 molecule, and NAD+ is reduced to NADH. This reaction connects glycolysis to the Krebs cycle. This is an MCQ on Link Reaction of Respiration or Pyruvate Decarboxylation Reaction in the […]

MCQ on Electron Transport System for NEET 2024
The electron transport system (ETS) is a series of protein complexes and electron carriers in the inner mitochondrial membrane that transfer electrons from NADH and FADH2 to oxygen, producing water. This process generates a proton gradient that drives ATP synthesis through oxidative phosphorylation. This is an MCQ on Electron Transport System for NEET 2024 Examination. […]

The CAM (Crassulacean Acid Metabolism) cycle is a photosynthetic adaptation in some plants allowing them to fix CO₂ at night, storing it as malic acid. During the day, CO₂ is released for photosynthesis. This conserves water, making it ideal for arid environments. This is an MCQ on CAM Cycle with Answer Key. <<< Back to […]

MCQ on C4 Cycle (Hatch and Slack pathway)
The C4 cycle (Hatch and Slack Pathway) is a photosynthetic process in some plants where CO₂ is initially fixed into a four-carbon compound. This adaptation minimizes photorespiration and enhances efficiency by concentrating CO₂ around RuBisCO, enabling better performance under high light intensity, high temperatures, and low CO₂ conditions. This is an MCQ on C4 Cycle […]

MCQ on Photorespiration (C2 Cycle)
Photorespiration is a process in plants where the enzyme RuBisCO oxygenates RuBP, leading to the release of CO₂ instead of its fixation. This occurs when oxygen levels are high, reducing photosynthetic efficiency and wasting energy, particularly under stress conditions like high temperatures. This is an MCQ on Photorespiration (C2 Cycle) in Plants. <<< Back to […]
