Yeast and glucose solution were kept at different temperatures. The volume of carbon dioxide collected in 30 minutes was measured.

Temperature ( $∘C^\circ\mathrm{C}$ )	15	25	35	45	55
Volume of $CO2\mathrm{CO_{2}}$ ( $cm3\mathrm{cm^{3}}$ )	14	32	51	26	0

Statement 1: the results prove that the optimum temperature is exactly 35 $∘C^\circ\mathrm{C}$

Statement 2: no gas was collected at 55 $∘C^\circ\mathrm{C}$ because the enzymes in the yeast were denatured

Statement 3: less gas was collected at 15 $∘C^\circ\mathrm{C}$ because the enzymes were denatured by the cold

Statement 4: the results show that the optimum temperature lies between 25 $∘C^\circ\mathrm{C}$ and 45 $∘C^\circ\mathrm{C}$

Which statements are correct?
