In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/reducing agent. Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.

Answers

Answer 1

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

However, the necessary condition for a reversible process is therefore the quasi-static requirement.

The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.

how do you propagate trees​

Answers

Answer:

The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.

Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?

Answers

The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.

First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.

In this case, when a flatworm is cut in half, we can see the following events happen:

At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.

This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

How many minutes are there in a 40-hour week?

A:2,000

B:2,400

C:1,400

D:1,200

Answers

The answer is B
Explanation:
You multiply 40 by 60 to get 2,400

There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.

What is Unit conversion?

Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.

Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).

The week of 40 hours can be converted into minutes by:

Number of minutes in 1 hour = 60

Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes

Therefore, the correct option is B.

What are some geological characteristics of glaciers in Glacier National Park?

Answers

Answer:

The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

the type of voltage-gated channel that possesses an inactivation gate that temporarily closes after the channel is active is the

Answers

The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.

In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).

Characteristically, this channel has two transmembrane voltage-dependent gates.

When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.

Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.

what factors determine if a species is fit to survive?

Answers

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

What is cell cycle?

The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.

Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.
