An experiment was conducted on isolated yeast cells to investigate the metabolic effects of two respiratory inhibitors, malonate and fluoride, on the pathway of cellular respiration. Table 1.1 displays the production rates of three key respiratory indicators: pyruvate, carbon dioxide (CO2\text{CO}_2CO2), and ATP, under different treatment conditions.
Table 1.1
| Treatment | Pyruvate (10−10 mol s−110^{-10}\text{ mol s}^{-1}10−10 mol s−1) | Carbon dioxide (CO2\text{CO}_2CO2) (10−10 mol s−110^{-10}\text{ mol s}^{-1}10−10 mol s−1) | ATP (10−10 mol s−110^{-10}\text{ mol s}^{-1}10−10 mol s−1) |
|---|---|---|---|
| Malonate | 4.804.804.80 | 0.800.800.80 | 1.201.201.20 |
| Fluoride | 0.000.000.00 | 0.000.000.00 | 0.000.000.00 |
| Control | 4.504.504.50 | 8.208.208.20 | 9.609.609.60 |
Using the data in Table 1.1, compare the metabolic effects of malonate and fluoride on yeast cell respiration, and deduce the stage of respiration targeted by each inhibitor.
