mel-nik [20]3 years ago
5 0

Answer:

The correct answer is option B: "I, II".

Explanation:

The synthesis of 5-phosphoribosylamine from phosphoribosyl pyrophosphate (PRPP) is inhibited allosterically by ATP and GTP and activated by PRPP via feed forward activation. The enzyme that regulate this process is the enzyme amidophosphoribosyltransferase (AMPRT), which is stimulated by increased PRPP concentrations and is inhibited allosterically by ATP and GTP as well as IMP, AMP, and GMP.

BrainlieSTTTTTT A gas is originally stored at a pressure of 25 atm with a volume of 3 L. If the pressure were increased to 75 at
Crazy boy [7]

Explanation:

Apply Boyle's Law :-

P1V1 = P2V2

  • Where P1 is 25 atm
  • V1 is 3L
  • P2 is 75 atm
  • V2 is what we need to find out.

25 × 3 = 75 × V2

\tt{V_2 = \dfrac{ 25 \times 3}{75}}

\tt{V_2 = \dfrac{75}{75}}

<u>So, the answer is d) Part, 1L .</u>

Hope it helps :)

A gas has a volume of 100.0 mL at a pressure of 600 mm HG. If the temperature is held consistent, what is the volume of the gas
Amiraneli [1.4K]

Answer: The volume of the gas at a pressure of 800 mm Hg is 75 mL.

Explanation:

Given: V_{1} = 100.0 mL,       P_{1} = 600 mm Hg

V_{2} = ?,        P_{2} = 800 mm Hg

According to Boyle's law, at constant temperature the pressure of given mass of an ideal gas is inversely proportional to volume.

Hence, formula used to calculate new volume of the gas is as follows.

P_{1}V_{1} = P_{2}V_{2}

Substitute the values into above formula.

P_{1}V_{1} = P_{2}V_{2}\\600 mm Hg \times 100.0 mL = 800 mm Hg \times V_{2}\\V_{2} = \frac{600 mm Hg \times 100.0 mL}{800 mm Hg}\\= 75 mL

Therefore, we can conclude that the volume of the gas at a pressure of 800 mm Hg is 75 mL.
