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

20 molecules of CO2 (assuming that oxaloacetate is being used only for TCA in these mitochondria).

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.

Does the enzyme make the reaction occur faster
Scrat [10]

Answer:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Explanation on Mitosis​
Kipish [7]
Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells

Some traits do not obey Mendel's law. For example, people with red hair tend to also have pale skin. Why might this be the case?
Misha Larkins [42]

Answer: Polygenic inheritance

Explanation:

Polygenic inheritance is a phenomenon that explains how a character like skin color show a range of more or less continuous variation due to many genes controlling it. And this is unlike Mendel traits that are controlled by single genes.

So, skin color in an individual is expressed as red hair and pale skin.
