Answer:

The assumption is quite reasonable.........

A lightbulb contains Ar gas at a temperature of 295K and at a pressure of 75kPa. The light bulb is switched on, and after 30 minutes its temperature is 418 K. What is a numerical setup for calculating the pressure of the gas inside the light bulb at 418K?

Which of the following is false? a. an apoenzyme can catalyze its reaction without its cofactor b an organic cofactor can be cal
ozzi

Answer: Option (a) is the correct answer.

Explanation:

A protein part of an enzyme is known as an apoenzyme. An apoenzyme combines with a cofactor, it is known as holoenzyme.

Without a cofactor an apoenzyme cannot function as cofactor helps in the formation of an active enzyme system and provides a specific site on enzyme for the substrate.

Whereas a non-protein chemical compound or metal ion that helps in the activity of enzyme as a catalyst is known as a cofactor. A metal ion cofactor can be bound directly to the enzyme or to a coenzyme.

The organic non-protein molecules which bind to the protein molecule to form an active enzyme is known as a coenzyme. Coenzymes are small size molecules which help the enzymes to act as a catalyst.

Therefore, we can conclude that the statement an apoenzyme can catalyze its reaction without its cofactor, is false.

What is the total number of moles of NaCl(s) needed to make 3.0 liters of a 2.0 M NaCl solution? *
RideAnS [48]

Answer:

6 moles of NaCl are needed to make 3.0 liters of a 2.0 M NaCl solution.

Explanation:

A 2M solution means that there are 2 moles of solute (NaCl in this case) in 1 liter of solution:

1 L solution-----2 moles of NaCl

3 L solution----x= (3 L solutionx2 moles of NaCl)/1 L solution= <em>6 moles of NaCl</em>
