Answer:

0.1501\ \text{M}

Explanation:

68\times 10^{-3}\times 1.4=0.0952\ \text{mol}

Concentration in solution

\dfrac{95.2}{288}=0.3305\ \text{M}

After dilution

144\times 0.3305=47.592\ \text{mmol}

Total volume =144+173=317\ \text{mL}

Final concentration =\dfrac{47.592}{317}=0.1501\ \text{M}

The final concentration is 0.1501\ \text{M}

Which statement about enzymes is true?
Lelechka [254]

statement about enzymes that is correct is

b. they are large molecules that increase the rate of biologically important reactions

Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.

Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.

Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.

so the correct answer is B.

Answer: bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Explanation: An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
