Question 1 - Cytochrome cc is a redox protein but myoglobin is an oxygen storage protein. Justify the statement.
Question 2 - Explain why the C=O stretching vibration of an aldehyde give rise to the strong absorption in the infrared, yet the absorption due to C=C vibration in an alkene is normally very weak?
