Artist 52 [7]

Answer:

The answer is

<h2>2.00 %</h2>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual measurement = 46.37 g

error = 47.25 - 46.37 = 0.88

The percentage error of the measurement is

P(\%) =  \frac{0.88}{46.37}  \times 100 \\  = 1.89777873...

We have the final answer as

<h3>2.00 %</h3>

Hope this helps you

The energy that is released when hydrogen ions pass through ATP synthase provides the energy needed to form ADP and phosphate fr
MArishka [77]

Answer:

True.

Explanation:

This process is known as chemiosmosis in which there is a movement of ions across semipermeable membrane. Hydrogen ions moves from region of its higher concentration to the region of lower concentration.  As this process belongs to the diffusion or osmosis of water molecules across cell membrane that is why known as chemiosmosis.

ATP synthase is an enzyme which function is to form ATP by using free energy generated in result of movement of hydrogen ions.
