Q2: What are the parts of an electromagnet?

A2: According to Sciencing, Significance. Electromagnets are a vital part of everyday life.

Operation. Electromagnets behave the same way as regular magnets.

Construction. The basic components of an electromagnet are a wire and a power source.

Special Types of Electromagnets. Solenoids are electromagnets that are in the form of a helix.

Q3: How is an electromagnet useful when compared to a permanent magnet?

A3: According to Toppr, The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.

What is the initial velocity of the reaction catalyzed by the wild-type enzyme when the substrate concentration is 10 mM?

Doss [256]

Answer:

50 micro mol/min

Explanation:

So, we have the following parameters which are going to help us in solving this particular Question or problem;

=> For the wild type enzyme, the value for the Maximum velocity = 100 micromol/min.

=> For the mutant type enzyme, the value for the Maximum velocity = 1 micromol/min.

So, we can determine or calculate the value for the initial velocity for each of the enzyme type by using the formula below;

Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Therefore, for the wild type enzyme; the Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Initial velocity =( 10mM × 100micromol/min) ÷ ( 10mM + 10 mM ) = 50 micro mol/min.

Initial velocity for the wild type enzyme = 50 micro mol/min.

The sugar pill serves as a control.

The control in experiments is a sample that remains the same throughout the experiment and it is used to compare the results of the main experiment to. It serves to guarantee that changes noted in the experiment are from the variables introduced and not something else.
