Confused about enzyme activation energy or exothermic vs endothermic reaction graphs? This short video makes it crystal clear in under 60 seconds! Watch how enzymes lower activation energy, making biochemical reactions faster and more efficient. Then see the difference between endothermic and exothermic reaction graphs—where energy is absorbed or released during chemical changes. Perfect for NEET, class 11/12, or anyone wanting a quick boost in biochemistry and thermodynamics concepts!
