Calcium in Biology – PowerPoint Presentation

This presentation explains the biological importance of calcium ions (Ca²⁺), their role as a second messenger, calcium homeostasis, and intracellular signalling mechanisms. It covers calcium-ATPase, the sodium–calcium exchanger, calmodulin, calcium-dependent protein kinase activation, muscle contraction and relaxation, the troponin complex, phosphorylase kinase activation, and epinephrine-mediated glycogenolysis.

Topics Covered:
• Biological functions of calcium ions
• Calcium homeostasis and transport mechanisms
• Calcium as a second messenger
• Calmodulin and protein kinase activation
• Role of calcium in muscle contraction and relaxation
• Troponin and tropomyosin regulation
• Activation of phosphorylase kinase
• Epinephrine signalling, cAMP and glycogenolysis

Suitable for undergraduate and postgraduate students of Biology, Zoology, Botany, Biochemistry and Physiology. Useful for classroom teaching, revision and examination preparation.
