GPCR, or G protein-coupled receptor, is a cell membrane protein that detects external signals and activates intracellular responses. It plays a crucial role in cell communication, mediating processes such as neurotransmission, immune response, and hormonal regulation in various physiological functions. This is an MCQ on G Protein-Coupled Receptors (GPCRs). | […]

Difference between Intrinsic and Extrinsic Pathways of Apoptosis
The intrinsic and extrinsic pathways are two mechanisms of apoptosis or programmed cell death. This classification is based on the source of stimuli that induces the apoptotic cell death. Intrinsic Pathway: This pathway is initiated within the cell due to internal stress, such as DNA damage or cellular damage. It […]

MCQ on Cell Signalling in Plants
MCQ on Cell Signalling in Plants: In plants, cell signalling occurs through various mechanisms, including phytohormones like auxins, cytokinins, and gibberellins. These molecules regulate growth, development, and responses to environmental cues by binding to receptors and initiating intracellular pathways, ensuring coordinated physiological processes.
