How many molecules of carbon dioxide (CO2) would be produced by five turns of the citric acid cycle?

Biology

1 answer:

ser-zykov [4K]4 years ago

8 0

Answer:

The correct answer is E) 10

Explanation:

Glucose is partially oxidized during the glycolysis process into two pyruvate molecules. Then these pyruvate molecules get totally oxidized into CO2 during the citric acid cycle. This citric acid cycle occurs in the matrix of mitochondria.

During a single turn of the citric acid cycle, 2 molecules of carbon dioxide are released. Apart from two molecules of CO2, 3 molecules of NADH, 1 molecule of FADH2 and 1 molecule of ATP or GTP are also produced.

So if 2 molecules of CO2 are produced in one turn therefore in 5 turn 10 molecules of CO2 will be produced.

What is the mechanism(s) that bordetella pertussis uses to invade epithelial cells in the lungs?

MaRussiya [10]

The mechanism of action of Bordetella pertussis is to stop the cilia of epithelial cells from beating.

<em>Bordetella pertussis</em> is a pathogenic, gram-negative bacteria. It is the causative agent of highly communicable respiratory disease known as pertussis or whooping cough.

The mechanism of action of Bordetella pertussis:

This bacterium colonizes the ciliated epithelial cells of the respiratory airways of the host.
A surface protein on the bacteria called filamentous haemagglutinin adhesin binds to sulfatides on the cilia of epithelial cells. When the bacterium is anchored, it releases tracheal cytotoxin, which prevents the cilia from beating.
As a result, the cilia in an organism's lungs are unable to sweep out foreign material, and the body reacts by causing the host to cough. When people cough, bacteria are released into the air, where they might spread to other hosts.
Another toxin called the pertussis toxin, often known as PTx, prevents adenylate cyclase from using ATP to convert to cyclic AMP. This results in over-conversion of ATP to cyclic AMP, which may interfere with cellular signaling systems. As a result, phagocytes are unable to respond to an infection effectively.

The elements sodium (na) has an atomic number of 11 with ine outer valence electron,this element would likely form

MrRa [10]

Cation. Sodium has 10 electrons with 1 outer valence electron, and outer valence electrons are positive. This means that it will have a charge of +1, and a cation is a positively charged ion that is attracted to the cathode during electrolysis, which is the decomposition (chemically) of something that happens after an electric current passes through it.
