Answer:

The answer is a heme cofactor.

Explanation:

Peroxidase is an enzyme that catalyzes oxidation/reduction reaction by using hydrogen peroxide as a substrate.  

Donor+H2O2 ↔ Oxidized donor + H2O

Peroxidase active site can contain a heme cofactor that has an iron ion and a porphyrin molecule that acts as an electron donor to the hydrogen peroxide which is then reduced to water.

Determine the new concentration, in mg/mL, of the starch solution you diluted in the Erlenmeyer flask. Recall from the Procedure
Semmy [17]

Answer:

0.05 mg/mL  ( B )

Explanation:

Given data:

20 mg/ml starch

2% solution = 2g of solute is in 100g of solvent

<u>Determine the new concentration in mg/ml </u>

Dilution equation = C1V1 = C2V2

new concentration ; applying the dilution factor

dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every  100 mL

∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
