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.

Which energy source produces carbon dioxide?
HACTEHA [7]
The answer is d. natural gas. All the other choices are alternative sources of energy, and do not produce or emit any greenhouse gas such as carbon dioxide (CO2). Natural gas, on the other hand, is an organic substance containing a significant amount of carbon, that when burned for fuel, results in the emission of CO2.

Meg used two examples to represent two different states of matter.
torisob [31]

Answer:

c  Example 1 represents a liquid and Example 2 represents a solid.

Explanation:

Example 1: Young children dancing slowly around one another

The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.

Example 2: Newborn babies sitting in their given spots in a crib

This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
