g In animal tissues the rate of conversion of pyruvate to acetyl-CoA is regulated by the ratio of phosphorylated and dephosphory
Colt1911 [192]

Answer: seen below.

Explanation: since the different means use in treating rabbit muscle mitochondria containing PDH complex. I will give different reactions that occurs.

The mitochondria preparation responds as follow;

Active pyruvate dehydrogenase (dephosphorylated) is converted to inactive pyruvate dehydrogenase (phosphorylated) and the rate of conversion of pyruvate to acetyl-CoA decreases.

The phosphoryl group on pyruvate dehydrogenase (dephosphorylated) phosphate is removed enzymatically to give active pyruvate dephosphorylated which increases the rate of conversion of pyruvate to acetyl-CoA.

Malonate inhibit succinate dehydrogenase, and citrate accumulates. Accumulation of this citrate inhibits citrate synthase, and acetyl-CoA accumulates. Increased level of this acetyl-CoA inhibits pyruvate dephosphorylated and the rate of conversion of pyruvate to acetyl-CoA decreases.

There is a series of nitrogen oxides with the general formula N?O?. What is the empirical formula of one that contains 30.45% ni
lions [1.4K]

Answer: The empirical formula of one that contains 30.45% nitrogen is NO_{2}.

Explanation:

Given: Mass of nitrogen = 30.45 g

Let us assume that the mass of given oxide is 100 grams.

As the atomic mass of nitrogen is 14.0067 g. So, moles of nitrogen will be calculated as follows.

Moles = \frac{mass}{molarmass}\\= \frac{30.45 g}{14.0067 g/mol}\\= 2.17 mol

Also, mass of oxygen = (100 - 30.45) g = 69.55 g

Atomic mass of oxygen is 15.9994 g/mol. So, moles of oxygen will be as follows.

Moles = \frac{mass}{molarmass}\\= \frac{69.55 g}{15.9994 g/mol}\\= 4.34 mol

The ratio of both the atoms is as follows.

\frac{4.34}{2.17} = 2

This means that gas has 2 moles of oxygen to 1 mole of nitrogen. Hence, the formula of oxide is NO_{2}.

Thus, we can conclude that the empirical formula of one that contains 30.45% nitrogen is NO_{2}.

The ratio of the moisture content in the air compared to the maximum amount of moisture that the air can hold at its current tem
PSYCHO15rus [73]
<h2>Relative Humidity</h2>

Explanation:

  • Humidity is the amount of moisture content present in the atmosphere.

    Humidity is of two types:

  1. Absolute humidity.
  2. Relative humidity.
  • Absolute humidity is the ratio of  the amount of moisture content in the air to the unit volume of the air.
  • Relative humidity can be derived as the ratio of moisture content in the air to the maximum amount of moisture that the air constitutes.
  • Hence, the required answer is Relative humidity.
