Chlorophylls are soluble in:
Correct answer: C. Carbon tetrachloride and alcohol
- A. Carbon tetrachloride
- B. Alcohol
- C. Carbon tetrachloride and alcohol
- D. Water
Explanation
Option C is correct.Chlorophylls are soluble in organic solvents, such as alcohol, ether, carbontetracholride and acetone. They are not soluble in water.The reason why chlorophylls are soluble in organic solvents is because they have a hydrophobic (water-fearing) side and a hydrophilic (water-loving) side. The hydrophobic side is made up of the long hydrocarbon tail of the chlorophyll molecule. The hydrophilic side is made up of the porphyrin ring and the magnesium atom. Organic solvents are also hydrophobic, so they can dissolve the hydrophobic side of the chlorophyll molecule. The hydrophilic side of the chlorophyll molecule is then exposed to the solvent, which allows the chlorophyll molecule to dissolve.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
