Topics in Cellular Processes

1

1. Cell Signaling

  • A receptor is a protein located either on the cell surface or inside the cytoplasm or the nucleus.
  • A chemical messenger to which a receptor responds is a ligand.
  • The association between a receptor and its corresponding ligand is highly specific.
2

2. Metabolic Pathways and Energy Use

  • Metabolism is the process through which living organisms take and utilise free energy for life processes.
  • Living organisms are of two types on the basis of taking free energy: phototrophs and chemotrophs.
  • Phototrophs use sunlight to convert simple molecules into energy-rich molecules.
3

3. Glycolysis and Fate of Pyruvate

  • Glycolysis is a universal catalytic pathway in all living cells and is also known as the Embden-Meyerhof-Parnas pathway.
  • Glycolysis occurs entirely in the cytosol.
  • The pathway begins with phosphorylation of glucose to glucose-6-phosphate by hexokinase.
4

4. Citric Acid Cycle and Electron Transport Chain

  • The citric acid cycle is also known as Kreb's cycle or Tricarboxylic acid cycle.
  • The citric acid cycle takes place inside mitochondria, unlike glycolysis which occurs in the cytosol.
  • Hans Kreb discovered the citric acid cycle.
