The amount of Peroxidase will be changed by
inessss [21]

Answer:

The amount of peroxidase will be changed by changing the amount of turnip extract used.

Explanation:

A) Adding more or less buffer to the test tube.

<em>B) Changing the amount of turnip extract used.</em>

C) Adding different amounts of water to the mixture.

D) Using different types of turnip extracts prepared for us.

Peroxidase is an enzyme that degrades hydrogen peroxide (H₂O₂), releasing oxygen at the end of the reaction. One of the vegetable sources to obtain peroxidase is turnip (Brassica Napus).

The experiment on which the question is asked has to do with the reaction in which H₂O₂ participates, as a substrate, and the turnip extract containing the enzyme peroxidase, with a change in color due to the release of oxygen.

It is clear that, if the amount of turnip extract in the reaction is changed, the amount of peroxidase added will change.

Which peritoneal fold attaches the liver to the anterior internal body wall?
Alex

The answer is falciform ligament. It also separates the left lobe into lateral and medial segments. It is a type of peritoneum (composed of two layers of tightly bound peritoneums). The ligament stretches from the underside of the diaphragm to the posterior surface of the sheath of the right rectus abdominis muscle, as low down as the umbilicus; by its right margin, it extends from the notch on the anterior margin of the liver, as far back as the posterior surface.
