Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. I now allow the TCA to run just enough to generate
lara31 [8.8K]

Answer:

The correct option is option D which is  10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.

Explanation:

As the complete question is not given, the complete question is as below

Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. After running the TCA to generate 20 molecules of CO2, how many molecules of oxaloacetate will be left in the mitochondria (assuming oxaloacetate is being used only for TCA in these mitochondria)?

A) 30 – each molecule of CO2 generated corresponds to an increase of one OAA

B) 20 – every two molecules of CO2 generated corresponds to an increase of one OAA

C) 0 – two molecules of CO2 generated corresponds to one AcCoA used in the TCA; each AcCoA requires one molecule of OAA

D) 10 – one molecule of OAA is regenerated for every molecule of AcCoA used

Each cycle of TCA result in consumption of 1 Acetyl-Coenzyme (AcCoA) and 1 Oxaloacetate (OAA) molecule to give rise to 3 molecules of NADH and 2 molecules of CO2 per cycle. But at the end of each cycle, OAA molecule is regenerated. So the number of oxaloacetate(OAA) molecules remains unchanged.

Thus the correct option is option D which is  10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.

In certain classes of antibody, the monomeric versions join to form dimers. what portions of the molecules adhere to each other
TiliK225 [7]
There are five classes of antibody.
1) <span>IgA (immunoglobin A)
2) IgD (immunoglobin D)
3) IgE (immunoglobin E)
4) IgG (immunoglobin G)
<span>5) IgM (immunoglobin M)

They form Y shaped antibodies. The crystallized fragment is the stalk of the Y shaped antibodies. The bond formed by this stalk will determine the form of the antibody. One Y is called monomer, two connected Ys are called dimers, and 5 connected Ys are called pentamers.</span></span>

¿Qué características crees que deben tener los métodos anticonceptivos para ser eficaces en el control de la natalidad?
Tanzania [10]

Answer:

Los métodos anticonceptivos para ser eficaces en el control de la natalidad deben ser seguros para las personas que los utilizan, es decir, no tener efectos adversos, o al menos, la menor cantidad posible. Ser reversibles, es decir, que no generen infertilidad de por vida. Deben ser además fáciles de usar, cómodos y fáciles de conseguir, esto es, económicos. Además deben ser eficientes en su objetivo de evitar la concepción, que es para lo que fueron creados.

Explanation:

La tasa de eficacia de un método anticonceptivo se mide por la cantidad de embarazos que se producen cada 100. Esta parece ser la característica más importante, y si bien es una de las más importantes, hay que tener en cuenta todos los otros factores mencionados, es decir que la gente pueda acceder a ellos, sean cómodos, seguros y a un precio coherente.
