Answer:
D. The volume of the solvent used was less than 5 liters.
Explanation:
- We have the rule: the no. of moles before dilution equal the no. of moles after dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 10.0 M, V before dilution = V of stock = ??? L.
M after dilution = 1.0 M, V after dilution = 5.0 L.
<em>V before dilution = V of stock = (MV) after dilution/M before dilution</em> = (1.0 M)(5.0 L)/(10.0 M) = <em>0.5 L.</em>
∴ The volume of the stock used is 0.5 L.
The volume of the solvent used is 4.5 L.
<em>D. The volume of the solvent used was less than 5 liters.</em>

Malonyl CoA regulates a variety of enzymes, including fatty acid synthase, acetyl-CoA carboxylase, and carnitine palmitoyltransferase I.
Malonyl CoA is an important regulatory molecule that is involved in the control of fatty acid synthesis. It is the precursor molecule to acetyl CoA and is produced in the cytosol of cells from acetyl CoA by the enzyme acetyl-CoA carboxylase. Malonyl CoA then serves as a substrate for a variety of enzymes, which are regulated by their levels.
One of the enzymes that Malonyl CoA regulates is fatty acid synthase (FAS). FAS catalyzes the conversion of acetyl CoA and malonyl CoA into long-chain fatty acids. The enzyme is activated when Malonyl CoA binds to the active site, which induces a conformational change in the enzyme that increases the affinity of the enzyme for its substrate.
Another enzyme that Malonyl CoA regulates is acetyl-CoA carboxylase (ACC). ACC catalyzes the carboxylation of acetyl CoA to form malonyl CoA. This enzyme is regulated by Malonyl CoA, as the presence of Malonyl CoA in the active site of the enzyme inhibits its activity. This serves to prevent the production of excessive amounts of Malonyl CoA, which could otherwise lead to excessive fatty acid synthesis.
Finally, Malonyl CoA also regulates the enzyme carnitine palmitoyltransferase I (CPT-I). CPT-I is responsible for the transport of long-chain fatty acids across the mitochondrial membrane, a process that is necessary for the oxidation of fatty acids. Malonyl CoA binds to CPT-I, inhibiting its activity and thus preventing fatty acid oxidation. This serves to maintain the levels of Malonyl CoA in the cytosol, ensuring that it can be used for fatty acid synthesis.

Explanation:
When all other variables are constant, we are allowed to use the formula
![\frac{T_{2} }{V_{2} } = \frac{T_{1} }{V_{1} } \\Which can be rewritten as T_{2} = \frac{T_{1} V_{2} }{V_{1} }if you make T2 the subject of the formula. This formula is true only if temperature is in Kelvin not degrees Celsius so T1 must be converted to KelvinNow to calculate T2[tex]T_{2}= \frac{296.15K*3.38.10^{3}L }{1.69.10^{3}L }= 592.3K](https://tex.z-dn.net/?f=%5Cfrac%7BT_%7B2%7D%20%7D%7BV_%7B2%7D%20%7D%20%3D%20%5Cfrac%7BT_%7B1%7D%20%7D%7BV_%7B1%7D%20%7D%20%5C%5C%3C%2Fp%3E%3Cp%3EWhich%20can%20be%20rewritten%20as%20T_%7B2%7D%20%3D%20%5Cfrac%7BT_%7B1%7D%20V_%7B2%7D%20%7D%7BV_%7B1%7D%20%7D%3C%2Fp%3E%3Cp%3Eif%20you%20make%20T2%20the%20subject%20of%20the%20formula.%20This%20formula%20is%20true%20only%20if%20temperature%20is%20in%20Kelvin%20not%20degrees%20Celsius%20so%20T1%20must%20be%20converted%20to%20Kelvin%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3ENow%20to%20calculate%20T2%3C%2Fp%3E%3Cp%3E%5Btex%5DT_%7B2%7D%3D%20%5Cfrac%7B296.15K%2A3.38.10%5E%7B3%7DL%20%7D%7B1.69.10%5E%7B3%7DL%20%7D%3D%20592.3K)
