[References) Which of the following statements explains why acetyl-CoA Iis considered the central molecule of metabolism? (Select all that apply.) O The addition of acetyl-CoA to compounds stabilises them. Acetyl-CoA contains a thioester bond that makes it one of the high energy compounds in metabolic pathways. O Acetyl-CoA is an inhibitor that plays a central role in regulating metabolic pathways. O Acetyl-CoA feeds directly into the citric acid cycle. U None of the above.
