<h2>TCA cycle </h2>

Explanation:

TCA or citric acid cycle is an oxidative pathway which occurs in matrix of mitochondria that completely oxidize Acetyl CoA in form of CO2 and produce NADH, FADH2 and GTP

The aim of this cycle is to fulfill the energy demand of cell

In the first step of the cycle, Acetyl CoA combines with a four-carbon acceptor molecule, oxaloacetate, to form a six-carbon molecule called citrate

After a quick rearrangement, this six-carbon molecule releases two of its carbons as carbon dioxide molecules in a pair of similar reactions, producing a molecule of NADH each time

The enzymes that catalyze these reactions are key regulators of the citric acid cycle, speeding it up or slowing it down based on the cell’s energy needs

The remaining four-carbon molecule undergoes a series of additional reactions, first making an ATP molecule—or, in some cells, a similar molecule called GTP—then reducing the electron carrier FAD to FADH2 and finally generating another NADH; This set of reactions regenerates the starting molecule, oxaloacetate, so the cycle can repeat

Overall, one turn of the citric acid cycle releases two carbon dioxide molecules and produces three NADH, one FADH2, one ATP or GTP

The citric acid cycle goes around twice for each molecule of glucose that enters cellular respiration because there are two pyruvates—and thus, two Acetyl CoA made per glucose

Four stage in which abortion cannot be done.
VikaD [51]

Answer:

Fourth trimester.

Explanation:

Fourth trimester is the fourth stage in which abortion can not be done because the baby is big enough in size and comes out from the womb. The abortion in this stage can put the life of the mother in danger so that's why abortion is not allowed. Newborn babies are learning to adjust itself to life outside the womb where it was warm so we can say that  fourth trimester is the stage in which abortion is risky and dangerous.

A constant rate of increase (rmax) for a population produces a growth graph that is J-shaped rather than a straight line. Why?
Alexus [3.1K]

Answer:

Explanation:

The line graph illustrates the temperatures in London, New York and Sydney on monthly average and the table introduces the information about the annual hours of sunshine for these cities. The overall view is that London is always exceeded by the rest in both the temperature and the number of sunshine hours.

To specify, the line graph shows that in New York, the average temperature goes up slightly from 4.5 degree in January to 8 degree in March, before a more significant increase to the highest of 30 degree in July, followed by a drop to 5 degree in December. Similarly, in London, after climbing gradually from the lowest point of 9 degree to the highest of 23 degree in July, the figure stays unchanged in the next month and then fall to 9.5 degree in December.

On the contrary, in Sydney, the temperature decrease insignificantly from 25.5 degree in January to the lowest of 16 degree in July, before a gradual rise to 25 degree in December. Meanwhile, the table indicates that New York has the largest number of sunshine hours per year with 2535 hours, came after by Sydney and London with 2473 hours and 1180 hours respectively.

In conclusion, London is likely to be the coldest city because its annual hours of sunshine is less than two others.
