vovangra [49]

It protects the organs of the body. Think about this..... Your bones are arranged so that each organ is protected. Each bone is like a border so that your organs are not exposed. If you didn't have bone then, if you got hurt then your vital organs could get hurt. It doesn't eliminate wastes from the body because that's the excretory system. It doesn't produce facial expressions since that is the nervous system ( heat is also controlled by the nervous system).

julsineya [31]

Answer: freezing

Freezing is defined as the process through which a substance changes its from from a liquid to a solid. As the liquid lava in the example has lost its thermal energy and thus has hardened, the phase change through which it has undergone is freezing. All liquids with the exception of helium undergo freezing then the average energy of the molecules decreases.

Solidification is another term often used to describe this phenomenon. However, it is much more general and can occur due to other factors such as reactions between different chemicals.

The total degradation of a fatty acid with an odd number of carbons yields acetyl-CoA and another compound, X. Show the structur

Brrunno [24]

Answer: X is propionyl-CoA, CH3CH2C0CoA

The structure and reaction pathway are shown in the attachments.

Explanation: In the oxidation of odd-number fatty acids, the substrate for the last pass through beta-oxidation is fatty acyl-CoA with a five-carbon fatty acid. This is oxidized and cleaved to acetyl-CoA and propionyl-CoA. Acetyl-CoA enters the citric acid cycle while the propionyl-CoA is converted in three enzymatic steps to succinyl-CoA which can then enter the citric acid cycle.

Step 1: Conversion of propionyl-CoA to D-methylmalonyl-CoA

Propionyl-CoA is carboxylated to D-methylmalonyl-CoA by the enzyme propionyl-CoA carboxylase, which contains the cofactor biotin. A molecule of ATP and Carbon (iv) oxide (in the form of hydrogen carbonate ion) is required also.

Step 2: Epimerization of D-methylmalonyl-CoA

D-methylmalonyl-CoA is epimerized by the enzyme methylmalonyl-Co epimerase to its L stereoisomer, L-methylmalonyl-CoA.

Step 3: Conversion of L-methylmalonyl-CoA to succinyl-CoA

This reaction is catalysed by methylmalonyl-CoA mutase which requires the coenzyme B12.
