  • Ribosomes & chromosomes
  • Smooth Endoplasmic Reticulum
  • Golgi complex
  • Rough Endoplasmic Reticulum

Cyclosis and amoeboid movements are due to:

  • Microtubule
  • Cilia
  • Intermediate filaments
  • Microfilaments

Most of the monosaccharides form a ring structure when in solution. For example ribose will form a five cornered ring known as:

  • Glyceraldehyde
  • Acetaldehyde
  • Glucopyranose
  • Ribofuranose

  • Carbohydrates
  • Protein
  • Water

The major enzymes involved in transfer of phosphate group from ATP to Glucose is:

  • Kinase
  • Isomerase
  • Dehydrogenase
