49. Synthesis of triacylglycerol in adipocytes requires high level of glucose in the blood, because:
(A) glycolysis of glucose provides high level of acetyl CoA for fatty acid synthesis.
(B) glycolysis of glucose provides high level of ATP.
(C) glycolysis of glucose provides dihydroxyacetone phosphate for glycerol phosphate synthesis.
(D) glycolysis of glucose provides high level of NADH for fatty acid synthesis.
(E) pentose phosphate pathway provides high level of NADPH for fatty acid synthesis.
