In a case where the energy source to be used it 1 malate unit, exactly how many ATP can beyielded?a. 4 b. 0 c. 2.5 d. 1.5 e. 6 f. 3Which is not true when it comes to the mitochondrial shuttle systems?a. In the malate-aspartate shuttle, electrons are transferred from NADH to NADHb. NADH produced from pyruvate oxidation requires a shuttlec. NADH produced from glycolysis cannot diffuse into the mitochondrial matrixd. In the glycerol phosphate shuttle, electrons are transferred from NADH to FADH2
