Explanation / Answer

79. D. Anabolic reactions are reactions that requires energy where catabolic reactions release energy

80. B. The first stage of catabolism is production of pyruvate followed by acetyl CoA

81. D protein synthesis takes place in ribosomes outside the nucleus

82. C . The molecules used as dorect source of energy is ATP

83. B. HYDROLYSIS of ATP to ADP is exothermic and vice versa is endothermic

84. A . The citric cycle takes place in mitochondria

85 C . NAD+ participates in reaction that produce phosphorylation
