Question

For the reaction in the plant cells 6CO2(g) + 12 H2O(l)→ C6H12O6(s) + 6 O2(g)+ 6H2O(l) Δ rG° = 3000 kJ/mol ATP→ ADP + PO3-4Δ r G° = -30 kJ/mol Glucose is stored in the plant cell as starch (C6H10O5)n To produce 162 g of starch how many moles of ATP are minimum required? (A) 100 mol (B) 10 mol (C) 20 mol (D) 200 mol

Tardigrade Admin · Accepted Answer

Mol. wt. of starch = 162 n ∴ moles of C6H12O6 to be produced = 1 mol ∴ moles of ATP required =(3000/30)=100 mol

$100 m o l$

$10 m o l$

$20 m o l$

$200 m o l$

$M o l . wt .$ of starch $= 162 n$
$∴$ moles of $C_{6} H_{12} O_{6}$ to be produced $= 1 m o l$
$∴$ moles of $A TP$ required $= \frac{3000}{30} = 100 m o l$

100mol

10mol

20mol

200mol

Mol.wt. of starch =162n ∴ moles of C6​H12​O6​ to be produced =1mol ∴ moles of ATP required =303000​=100mol

$100 m o l$

$10 m o l$

$20 m o l$

$200 m o l$

$M o l . wt .$ of starch $= 162 n$
$∴$ moles of $C_{6} H_{12} O_{6}$ to be produced $= 1 m o l$
$∴$ moles of $A TP$ required $= \frac{3000}{30} = 100 m o l$
