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 […]
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 […]
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 […]
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 […]
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) […]
The Calvin cycle, also known as the C3 cycle, is a process in photosynthesis where carbon dioxide is converted into organic compounds like glucose. It consists of three phases: carbon fixation, reduction, and regeneration of ribulose-1,5-bisphosphate (RuBP). This is an MCQ on C3 Cycle of Photosynthesis. You may also like: […]

What is Shine Dalgarno Sequence? The Shine Dalgarno sequence aka SD Sequece is a ribosomal binding site in bacterial and archaeal mRNA. Usually, it is located around 8 bases upstream of the start codon (AUG). The SD sequence helps to recruit the ribosome to the mRNA to initiate protein synthesis […]
Koch’s postulates are four criteria developed by Robert Koch to establish a causal relationship between a microorganism and a disease. They include isolating the microbe, infecting a healthy host, observing the same symptoms, and re-isolating the microbe for confirmation. With this MCQ on Koch Postulates you can understand What is […]
