The β-oxidation of odd-numbered FAs presents a small problem in that once most of the oxidation has occurred, the last component
IrinaK [193]

Answer:

Maybe that your question is incomplete,  in the options following the statement listed none is correct ...

The procedures would have the following order:

1-Propionyl-CoA is converted to Methylmalonyl-CoA thanks to the enzyme Porpionyl-Carboxylase CoA which adheres to a carboxyl modifying the chemical structure (This enzyme depends on ATP, biotin and bicarbonate, to carry out the reaction).

2-Then, Methylmelanolyl-CoA is adhered to a radical, thanks to the enzyme methylmalonyl-CoA racemase, thus generating (R) -methylmalonyl-CoA as a product of the reaction.

3- And finally, (R) -methylmalonyl-CoA is converted to succinyl-CoA, an intermediate of the tricarboxylic acid cycle, by the enzyme methylmalonyl-CoA mutase, which requires cobalamin to catalyze carbon-carbon bond migration.

4-The mechanism of the methylmalonyl-CoA mutase begins with the cleavage of the bond between the 5 'of CH2-5'-deoxyadenosyl and cobalt, which is in its 3 + (III) oxidation state, which produces a 5'-radical. deoxyadenosil and cabalamin in the state of reduced oxidation Co (II)

Explanation:

Propionyl-CoA is important to know that it can come from different biological rations of the organism, such as: beta oxidation (of odd-chain fatty acids), the metabolism of isoleucine and valine and As a product of α-ketobutyric acid, which in turn it is a product of the metabolism of threonine and methionine.

Varvara68 [4.7K]

Diabetes insipidus is a disease characterized by excessive thirst and the excretion of large amounts of highly diluted urine, which can not be reduced by a reduction in fluid intake.

Diabetes insipidus is due to a deficiency of antidiuretic hormone or insensitivity of the kidneys to this hormone. This hormone causes water reabsorption via action on the distal segment of the nephron during dehydration.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
expeople1 [14]

Answer

a balance and a graduated cylinder

Explanation

Density is mass per unit and it is property  characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.

For a student to measure the density of seawater  he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample  and then a graduated cylinder to determine the volume.

Explain how bacteria are both helpful and harmful to our bodies.
vovangra [49]

Sample Response:

Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat. Bacteria are also helpful because they are used in medicine to help us overcome disease. Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.

This is a sample response, so it's 100% correct. Peace!
