In Sparged stirred-tank bioreactor, the stirrer facilitates mixing and oxygen availability throughout the bioreactor-NCERT
In Sparged stirred-tank bioreactor, the stirrer facilitates mixing and oxygen availability throughout the bioreactor – NCERT Simple Stirred Tank Bioreactor Oxygen enters only at the liquid surface. Agitator helps mixing but no air sparging. Best for low oxygen-demand processes. Lower oxygen transfer efficiency. Sparged Stirred Tank Bioreactor Sterile air is sparged directly into liquid. Agitator

NADH is oxidised to NAD+rather slowly in fermentation, however the reaction is very vigorous in case of aerobic respiration.
NADH Oxidation: Fermentation vs Aerobic Respiration Fermentation (Anaerobic) Final electron acceptor: Organic molecules (e.g., pyruvate) Oxidation of NADH is slow Less energy released (ΔG less negative) ~0 ATP produced directly from NADH Occurs in cytoplasm Aerobic Respiration Final electron acceptor: Oxygen (O₂) Oxidation of NADH is vigorous and fast Large energy release (ΔG highly negative)

Animal Tissue – NCERT – 🧬 Microvilli vs Cilia — Why They’re Found in Specific Systems
🧬 Microvilli vs Cilia — Why They’re Found in Specific Systems 📌 Microvilli: Where & Why? Found in: Digestive, Urinary, and Reproductive Tracts Function: Absorption and surface area enhancement. Why only here? These systems need to absorb nutrients (digestive), reabsorb water/ions (urinary), or secrete/absorb substances (reproductive). Microvilli are microscopic finger-like projections of the plasma membrane
