The correct answer is: oxaloacetate
Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.
The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.
Complete question:
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.
A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.
Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).
Answer:
The probability that the second child will also have the disease is 1/16.
Explanation:
<u>Available data:</u>
- Two genes independently inherited: one for blood type, the other for disease
- Man with type A blood x Woman with type B blood
- Both parents are heterozygous for the gene that causes the disease; Dd
If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.

Answer: C
Explanation: Water is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. Which is both positive and negative on opposite ends.
It could be B as well but, I believe it's C
It’s a study of unusual behaviors,emotion,and thought hope this helped
Answer:
E = The activation energy barrier for this reaction can not easily be surmounted.
Explanation:
Starch:
Starch is a polymeric carbohydrate consist of various glucose units join together through glycosidic bonds.
Reason why it is not dissolve at room temperature:
When starch is added into water it form granules with cold water and can be soluble by heating.
At a room temperature the starch does not readily decompose to from the solution by decomposing into simple sugar because the activation energy barrier for this reaction can not easily be surmounted at a room temperature.
