Energy Storage in Chemical Bonds — NEET Biology
📚 Practice ConceptLiving organisms have the capability of extracting energy from oxidisable substances and store this in the form of bond energy. Special substances like ATP, carry this energy in their chemical bonds. The process through which
Which of the following statements correctly describe the role of sunlight as the ultimate energy source for most living forms on Earth? S1: Sunlight directly provides energy for all metabolic activities in both plants and animals. S2: Green plants convert solar energy into chemical energy through photosynthesis, forming the foundation of energy flow in ecosystems. S3: The chemical energy stored in organic compounds produced by plants is transferred to heterotrophs through food chains. S4: Sunlight stimulates the release of CO2 from heterotrophs, thereby directly supporting carbon fixation in plants. S5: The intensity of sunlight dictates the rate of all enzymatic reactions in organisms, irrespective of their nutritional mode.
