In a Southeast coast village, illegal cyanide fishing is practiced Fishermen capture line fish for aquarium. This has led to significant die - off of non -target coral reef species. A marine biologist Dr. Inn collects tissue samples from affected damselfish. Cyanide is a potent inhibitor of cytochrome c oxidas e Table; Metabolic analysis of Damselfish Gill Tissue . Sample Cytochrome c oxidase activity %of normal Gel cell membrane integrity (% of cells damaged) Gill ATP concentration (mM) Oxygen upta ke(mg o /g/h) Unaffected fish 100 5 4.8 9.5 Cyanide exposed fish 3 60 0.8 1.2 Tasks a) Explain in simple steps how cyanide inhibition of cytochrome c oxidase leads to the changes shown in the table. b) Using the information provided, propose strategies to solve the challenges. Item 2. In a school, greenhouse, maize (C4 plant) developed yellow patches and stunted growth under prolonged temperature fluctuated widely and carbon dioxide concentration was low Microscopy revealed partial loss of Kranz anatomy and reduced PEP carboxylase activity .

Analyze how light duration, temperature fluctuation and carbon dioxide concentration affect C4 enzyme activities and chloroplast structures. .Explain how how changes in these variables influence micromolecules synthesis (starch, proteins, lipids ) and stomatal regulation. Propose integrated strategies to optimize each factor and restore healthy photosynthesis and growth . Item 3. In a busy Kampala hospital, …
