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 […]
Molecular chaperones are proteins that assist in the proper folding, assembly, and stabilization of other proteins. They prevent misfolding and aggregation, guide proteins to their functional conformation, and can help refold or target damaged proteins for degradation. This is an MCQ on Protein Chaperones (MCQ on Molecular Chaperones). Molecular Biology […]
Caspases are a family of protease enzymes that play essential roles in apoptosis (programmed cell death) and inflammation. They cleave specific proteins at aspartic acid residues, triggering cellular processes such as DNA fragmentation and membrane blebbing during apoptosis. This is an MCQ on Caspases in Apoptosis (Structure and Functions of […]
