✍️ Sample BIOINTERACTIVE Questions & Answers
1. What is chlorophyll fluorescence used to assess in photosynthesis?
Chlorophyll fluorescence is a non-invasive technique used to assess the efficiency and activity of Photosystem II (PSII) in photosynthesis. By measuring the re-emitted light from chlorophyll, scientists can gain insights into how effectively light energy is being captured and utilized in the initial stages of photosynthesis, indicating plant stress or health.
2. Which mineral nutrient is essential for chlorophyll synthesis and is often the primary limiting nutrient for photosynthesis in natural ecosystems?
Nitrogen is a key component of chlorophyll and RuBisCO; nitrogen deficiency leads to yellowing (chlorosis) and severely reduced photosynthesis.
3. Which plants use CAM photosynthesis?
CAM photosynthesis is common in succulent plants like cacti, agaves, and pineapples that live in arid environments.
4. How many photons are required to produce one O2 molecule from water splitting?
Eight photons (4 per photosystem × 2 photosystems) drive the reactions needed to split two water molecules and release one O2.
5. What is the primary function of the antenna complex (light-harvesting complex) in photosystems?
Antenna complexes contain arrays of chlorophyll and accessory pigment molecules that absorb photons and funnel excitation energy to the reaction center via resonance energy transfer.
6. What is photorespiration?
Photorespiration occurs when RuBisCO oxygenates RuBP instead of carboxylating it, wasting energy and releasing CO2 without fixing carbon.
