During glycolysis, if radiolabelled the glucose at 3 or 4 carbon then what will be the correct prediction about radiolabelling in the cycle?

#Unit 6. System Physiology – Plant
  1. Glucose radiolabelling carbon do not enter into the TCA cycle

  2. Pyruvate 1 carbon will not be radiolabelled
  3. pyruvate 1 carbon will be radiolabelled and enter into the TCA cycle
  4. in citric acid cycle, only carboxylic group of citrate will be radiolabelled
