Q7:
(a) Enlist various photosynthetic pigments. Give a detailed account of chlorophyll synthesis along with the enzymes involved in the process. Also mention the role of carotenoids in photosynthesis.    (20 Marks)
Ans: 

Introduction: 
Photosynthetic pigments are molecules that absorb specific wavelengths of light during photosynthesis, enabling plants to convert light energy into chemical energy. The main photosynthetic pigments are chlorophylls and carotenoids.

Various Photosynthetic Pigments:

  • Chlorophyll a: It is the primary pigment responsible for capturing light energy in photosynthesis. It absorbs red and blue light and appears green.

  • Chlorophyll b: This pigment complements chlorophyll a by absorbing light at slightly different wavelengths. It expands the range of light that can be utilized for photosynthesis.

  • Carotenoids: These include carotenes (like beta-carotene) and xanthophylls. They absorb light in the blue and green regions and appear yellow, orange, or red. They play a crucial role in photoprotection.

Chlorophyll Synthesis:
1. Aminolevulinic Acid (ALA) Synthesis:

  • ALA is the precursor molecule for chlorophyll synthesis.
  • Enzyme: ALA synthase catalyzes the formation of ALA from glycine and succinyl-CoA.

2. Porphyrin Synthesis:

  • ALA is converted into porphobilinogen through a series of enzymatic reactions.
  • Enzymes: Various enzymes like porphobilinogen deaminase and uroporphyrinogen III synthase are involved.

3. Chlorophyll Precursor Formation:

  • Porphobilinogen is converted into chlorophyllide, a precursor of chlorophyll.
  • Enzymes: Ferrochelatase inserts iron into the chlorophyll molecule.

4. Chlorophyll Formation:

  • Chlorophyllide is modified to form chlorophyll a and b.
  • Enzymes: Chlorophyll synthase plays a key role in this final step.

Role of Carotenoids:

  • Accessory Pigments: Carotenoids expand the range of light absorption, complementing the function of chlorophylls.

  • Photoprotection: They dissipate excess light energy as heat, protecting plants from damage caused by excessive light intensity.

Conclusion: 
Photosynthetic pigments, especially chlorophylls and carotenoids, are crucial for capturing light energy in photosynthesis. The synthesis of chlorophyll involves multiple enzymatic steps, starting from ALA production to the formation of chlorophyll a and b. Carotenoids play a vital role in broadening the spectrum of light absorption and in photoprotection.

(b) List the reactions of Calvin Cycle and Hatch-Slack Cycle for CO2 fixation in plants along with enzymes involved.    (20 Marks)
Ans: 

Introduction: 
The Calvin Cycle and Hatch-Slack Cycle (C4 pathway) are two key processes involved in carbon fixation during photosynthesis.

Calvin Cycle Reactions:

  • Carbon Fixation (RuBP Carboxylation): Enzyme: Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the addition of CO2 to ribulose-1,5-bisphosphate (RuBP), forming two molecules of 3-phosphoglycerate (3-PGA).

  • Reduction Phase: ATP and NADPH produced in the light reactions are utilized to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

  • Regeneration of RuBP: Some G3P molecules are converted back into RuBP using ATP.

Hatch-Slack Cycle (C4 Pathway) Reactions:

  • CO2 Fixation (Pep Carboxylation): Enzyme: Phosphoenolpyruvate carboxylase (PEP carboxylase) catalyzes the addition of CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate (OAA).

  • Decarboxylation (C4 Acid Decarboxylation): OAA is converted into malate, which releases CO2.

  • Calvin Cycle (C3 Cycle): Malate is transported to the bundle sheath cells, where it releases CO2 for the Calvin Cycle.

Conclusion: 
The Calvin Cycle and Hatch-Slack Cycle are crucial processes for CO2 fixation in plants. The Calvin Cycle involves carbon fixation, reduction, and RuBP regeneration. In the Hatch-Slack Cycle, CO2 is initially fixed into a C4 compound (OAA) through PEP carboxylation, followed by decarboxylation and release of CO2 for the Calvin Cycle.

(c) Briefly discuss the pathways of carbohydrate metabolism in plants.    (10 Marks)

Carbohydrate metabolism in plants involves the synthesis (anabolism) and breakdown (catabolism) of carbohydrates for energy and structural components.

Pathways of Carbohydrate Metabolism:
1. Photosynthesis:

  • Plants synthesize glucose and other sugars from CO2 and water in the presence of light, using chlorophyll pigments and enzymes.
  • Location: Chloroplasts

2. Glycolysis:

  • Glucose is broken down into two molecules of pyruvate, producing ATP and NADH.
  • Location: Cytoplasm

3. Gluconeogenesis:

  • Synthesis of glucose from non-carbohydrate precursors (like pyruvate, lactate, amino acids) during low glucose conditions.
  • Location: Mostly in the liver and kidneys.

4. Glycogenolysis:

  • Breakdown of glycogen into glucose units for energy release.
  • Location: Liver and muscle cells.

5. Glycogenesis:

  • Synthesis of glycogen from glucose for short-term energy storage.
  • Location: Liver and muscle cells.

6. TCA Cycle (Citric Acid Cycle):

  • Further breakdown of pyruvate into CO2, producing ATP, NADH, and FADH2.
  • Location: Mitochondria

7. Pentose Phosphate Pathway:

  • Produces NADPH and ribose-5-phosphate (for nucleotide synthesis) from glucose-6-phosphate.
  • Location: Cytoplasm

8. Respiration:

  • Oxidation of organic molecules (glucose, fatty acids) to generate ATP.
  • Includes glycolysis, TCA cycle, and electron transport chain.
  • Location: Cytoplasm and mitochondria.

Conclusion: 
Carbohydrate metabolism in plants encompasses a range of processes including photosynthesis for sugar synthesis, glycolysis for glucose breakdown, and various pathways for storage and utilization of carbohydrates. These pathways collectively ensure a continuous supply of energy and structural components essential for plant growth and development.

  • Mid-Day Meal Scheme: This program aims to improve the nutritional status of school-going children by providing cooked meals in schools.

  • Integrated Child Development Services (ICDS): ICDS provides supplementary nutrition, immunization, and health check-ups to pregnant women, lactating mothers, and children below 6 years.

  • National Food Security Act (NFSA): NFSA aims to provide food and nutritional security by ensuring access to adequate quantities of quality food at affordable prices.

Strategies for Sustainable Agricultural Production:

  • Crop Diversification: Encouraging farmers to cultivate a variety of crops helps in reducing the risk of crop failure and promotes sustainable land use.

  • Promotion of Organic Farming: Organic farming practices minimize the use of synthetic inputs, promote soil health, and reduce environmental impacts.

  • Water Conservation and Management: Efficient water use, through techniques like drip irrigation and rainwater harvesting, is crucial for sustainable agriculture.

  • Integrated Pest Management (IPM): IPM focuses on natural pest control methods, reducing reliance on chemical pesticides.

Conclusion: 
Government programs like PDS, Mid-Day Meal, ICDS, and NFSA play a vital role in ensuring food security. In tandem, promoting sustainable agricultural practices such as crop diversification, organic farming, water conservation, and IPM are essential for long-term food security and environmental sustainability.
