Question

Manganese in toxic concentrations leads to the deficiency of ______.

Answer 1

Manganese toxicity in Animals:

1. Manganese in toxic concentrations of manganese toxicity leads to the deficiency of calcium, iron, and magnesium as it competes with iron and magnesium for nutrient uptake.
2. It can result in a permanent neurological disorder known as manganism with symptoms including neuropsychiatric manifestations, tremors, difficulty walking, and facial muscle spasms. These symptoms are often preceded by other lesser symptoms, including irritability, aggressiveness, and hallucinations.
3. On the cellular level, it leads to alterations in glutamate and glutamine metabolism and mitochondrial function and triggers cellular apoptosis and necrosis.
4. Inhaled manganese can cause inflammation of the lungs. Symptoms might include cough and bronchitis.

Manganese toxicity in Plants:

• Mn toxicity leads to the appearance of toxicity symptoms.
• For example: - Chlorosis in young leaves, necrotic dark spots on mature leaves, and crinkled leaves, ultimately inhibiting plant growth.

Final Answer: Manganese (Mn) in toxic concentration leads to the deficiency of calcium, iron, and magnesium.
