Photosynthesis Basics & Empirical Equation — NEET Biology
📚 Practice ConceptBy the middle of the nineteenth century the key features of plant photosynthesis were known, namely, that plants could use light energy to make carbohydrates from CO₂ and water. The empirical equation representing the total process of photosynthesis for oxygen evolving organisms was then understood as:
Which of the following statements about the general process and components of photosynthesis are NOT correct? S1: The empirical equation for photosynthesis for oxygen evolving organisms represents water as the primary source of electrons and protons. S2: The overall process of photosynthesis is a single-step reaction that occurs uniformly throughout the chloroplast. S3: The main energy input for driving the synthesis of organic compounds in photosynthesis is chemical energy stored in ATP. S4: Chlorophyll 'a' is solely responsible for absorbing all wavelengths of light used in photosynthesis, while accessory pigments are not directly involved in light absorption. S5: The splitting of water is closely associated with Photosystem II and directly contributes to the accumulation of protons within the thylakoid lumen.
