9. A graduated cylinder is filled with water to a level of 40.0 mL. When a piece of copper is lowered into the cylinder, the wat
horsena [70]

Answer:

Mass = 208.26 g

Explanation:

Given data:

Volume of water = 40.0 mL

Volume of water + copper = 63.4 mL

Volume of copper = ?

Density of copper = 8.9 g/cm³

Mass of copper = ?

Solution:

Volume of copper:

Volume of copper = (Volume of water + copper ) - Volume of water

Volume of copper =  63.4 mL -  40.0 mL

Volume of copper = 23.4 mL

Mass of copper:

density = mass/volume

8.9 g/cm³ = mass/23.4 mL

 cm³ = mL

Mass = 8.9 g/mL × 23.4 mL

Mass = 208.26 g

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.
