Q28. NADH and NADPH are activated electron carrier molecules that function in completely different metabolic reactions. Which of the following statements are True (T) or False (F)? Your answer would be a fourletter string composed of letters T and F only, e.g., TTTT. 1. Both are electron carriers in oxidation-reduction reactions. 2. NADPH is the electron donor in biosynthetic reactions while NAD+ is the electron acceptor in catabolic reactions. 3. The reduced form of NADPH is present in the cell at higher ratio than the oxidized form. 4. The reduced form of NADH is present in the cell at higher ratio than the oxidized form. FTFT TTTF TTFT TFTT.
