In yeast, ethanol is produced from glucose under anaerobic conditions. A cell‑free yeast extract is placed in a solution that co
nadezda [96]

Answer:

0.35 milli moles of ethanol can be theoretically be produced under these conditions.

Explanation:

C_6H_{12}O_6 + 2 ADP + 2 Pi\rightarrow 2 C_2H_5OH + 2 ATP + 2 CO_2

Moles of glucose = 3.50\times 10^2 milli mole

Moles of ADP = 0.35 milli mole

Moles of Pi = 0.35 milli mole

Moles of ATP = 0.70 milli mole

As we can see that ADP and Pi are in limiting amount which means tat they are limiting reagent. So, the moles of ethanol produced will depend upon the moles of ADP and Pi.

According to reaction, 2 moles of ADP gives 2 moles of glucose.

Then 0.35 milli moles of ADp will give :

\frac{2}{2}\times 0.35 mmol=0.35 mmol of ethanol

0.35 milli moles of ethanol can be theoretically be produced under these conditions.

An experiment calls for 7.57g of sugar. You have a sugar son that is 5% by weight (for every 100g there is 5g of sugar). How man
Soloha48 [4]

Answer:

mL sugar sold needed = 2.2215 mL sugar

Explanation:

mass sugar = 7.57 g

∴ wt% = 5% = (g sugar/g sln)×100

⇒ 0.05 = g sugar/g sln

∴ g sln = 100 g

⇒ g sugar = 5 g

∴ δ sugar = 1.157 g/mL

⇒ mL sugar = (5 g)×(mL/1.157 g) = 4.322 mL

⇒ mL sugar needed = (7.57 g)/(1.157 g/mL) = 6.543 mL

mL of the sugar sold needed = 6.543 mL - 4.322 mL = 2.2215 mL sugar
