( ) NADH normally occurs in biosynthesis pathway, while NADPH occurs primarily in biodegradation pathway ( ) TCA cycle produces ATP directly ( ) Carbohydrate produced by photosynthesis occurs in the dark period ( ) Lipid bilayer takes part in mass transfer, energy production and signal communication ( ) Biochemical reaction has not space but substrate specifications ( ) Degradation of lipid can provide much more energy and water than carbohydrates ( ) NADPH is necessary for maintaining the reductive environments for blood cells ( ) Proline often occurs in a terminal and turn of ?-helix of protein ( ) Alpha helix and beta-sheet of protein is due to hydrogen bond, but subunits of hemoglobulin are arranged due to hydrophobic force. ( ) Change in conformation is normally accompanied by breakage of chemical bond(s) ( ) Pre-mRNA transcripted from DNA for prokaryotes normally does not need any processing to form the f
