The proportion of the carbon dioxide exhaled derived from the oxidation of pyruvate to acetyl CoA is 1/3.
Pyruvate is produced by glycolysis in the cytoplasm and its oxidation takes place in the mitochondrial matrix before chemical reactions begin, pyruvate enters the mitochondrion crossing the inner membrane and arriving at the matrix.
Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂
This is the reaction of the conversion of pyruvate into acetyl CoA.
1 molecule of pyruvate is converted into 1 molecule of carbon dioxide.
Also, 2 molecules of pyruvate are converted into 2 molecules of carbon dioxide (as glucose on glycolysis yields 2 molecules of pyruvate).
Acetyl-CoA also contributes to the citric acid cycle and generates two molecules of CO₂.
Pyruvate thus generates a total of 3 molecules of CO₂, whereas glucose generates 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate)
Thus, Fraction = 2/6 = 1/3.

the hepatic portal system drains blood from the digestive tract and the spleen, gallbladder, and pancreas. what constituents would you expect to be in the blood that enters the liver and what might the liver do with what it receives? explain.
The hepatic portal system deliver de-oxygenated blood to the liver for detoxification
The elements of the hepatic portal system are:
The primary vein that connects to the liver is called the hepatic portal vein. It develops where the inferior and superior mesenteric veins meet.
The inferior mesenteric vein joins the portal vein after receiving blood from the colon and rectum.
The superior mesenteric vein joins the hepatic portal vein after draining blood from the small intestine.
The splenic vein from the spleen and the gastric vein from the stomach come together to produce the gastrosplenic vein. Within the pancreas, it connects with the mesenteric vein.
The hepatic portal system cannot recognize substances meant to support it because it is made to remove poisons from the body causing detoxification

A geneticist found that a particular mutation did not affect the protein coded by a gene. What do you think is the most likely type of mutation in this gene? Why?
Mutation that did not affect the protein coded by a gene is silent point mutation .
Silent mutations generally occur when the shift of a single DNA nucleotide within a protein-coding portion of a gene does not disturb the sequence of amino acids that make up the gene's protein. Mutations that cause the modified codon to produce an amino acid with identical functionality are also classified as silent.
Silent mutation can some times be harmful it may cause pause during reading of genes .Many studies have also shown how silent mutation is responsible for many life threatening disease like breast cancer .

Elisa is traveling from Winston Salem to Las Angeles to visit Yetzeli who is 2,439 miles away. By plane it takes her 6 hours. Using the same route back it takes 8.5 hours. Calculate the speed of both routes and why the difference in the return trip.
The speed of both routes is 654.2 km/s and 461.78 km/s respectively.
Calculation:-
1 mile = 1.61 km
2,439 mile = 2,439×1.61 km
= 3925.19 km
Speed of the First route,
Given time = 6 hours
displacement = 3925.19 km
Speed = 3925.19 km/ 6

- Explain why an element's charge is related to the group on the periodic table to which it belongs
Answer:
Because of the elements' number of valence electrons.
Explanation:
the number of valence electrons (number of electrons in the outermost shell) determines the number of bonds an element can make and how close they are to having a filled shell, which elements are the most stable when their outermost shell is filled (8 electrons for smaller elements). For example, in group 1, the elements have one valence electron, which in order to have a filled shell, they would have to lose one electron. That would make their charge +1. On the otherhand, in group 7, the elements have 7 valence electrons. In order to achieve a full outer shell, they would have to gain one more electron. For example, Cl will form an ionic bond with Na (group 1), which Cl will take Na's 1 valence electron, resulting in a total of 8 valence electrons, which Cl will become -1 charge (one more electron than it originally has) and Na will become a +1 charge (one less electron than it originally has).
Because the group number represents the number of valence electrons in the outermost energy level of an atom, and the charge of an element is determined by the number of valence electrons it has.
What is valence electron?Valence electrons are electrons that are found in the outermost energy level of an atom. They are responsible for the chemical properties of an element and play a crucial role in determining how the element will react with other elements.
Valence electrons are important because they are the ones that are involved in forming chemical bonds with other atoms. The number of valence electrons an element has is determined by its atomic number
Valence electrons are important because they are the ones that are involved in forming chemical bonds with other atoms.
