Where do the electrons in the electron transport chain come from?

1 answer:

6 0

According to the research, the correct option is NADH and FADH2. The electrons in the electron transport chain come from NADH and FADH2.

<h3>What is the electron transport chain?</h3>

It is the series of oxidation-reduction reactions that releases ATP in prokaryotes attached to the plasma membrane and in eukaryotes it is found in the inner membranes of chloroplasts and mitochondria.

In this sense, this process is capable of using the reducing power of NADH or FADH2 with a high energy level to transfer protons to the interior of the thylakoid or mitochondria membrane.

Therefore, we can conclude that electrons are transferred from NADH and FADH2 along the electron transport chain, while energy is released in the form of ATP.

Which is the least number of seismograph stations needed to locate the epicenter of a earthquake

Hunter-Best [27]

At least three seismograph stations are needed to locate the epicenter of a earthquake.

Further Explanation:

An earthquake occurs when two region of the earth slip past each other. Fault plane is the area where the slip occurs. Hypocenter is the region below the earth’s surface where earthquake starts while the epicenter is the region above it.

The earth consists of four major layer:

1. Inner core

2. Outer core

3. Mantle

4. Crust

Seismographs is an instrument used to record the earthquake. The recording done by this instrument is called as the seismograms.

The seismograph comprises of:

1. A base: is fixed tightly in the ground

2. Heavy weight: hangs freely

When the earthquake occurs, the ground shakes and in turn the seismograph also shakes while the hanging weight does not shakes. During the earthquake, the difference in the location between the shaking piece and the motionless piece is recorded. Magnitude of the earthquake is recorded as one for each earthquake. The magnitude of earthquake is measured by the Richter scale but is more commonly measured through moment magnitude scale.

This can be possible because we no longer need to use a large hose and spray water on the roads and let the dirty water drain away back into seas and rivers and create water pollution. However, this methods requires a large amount of labor and time.

Maurinko [17]

Answer:

The correct answer is b. to serve as an outgroup.

Explanation:

When studying the phylogeny of a group, there must be an outgroup that can serve to understand which characters are plesiomorphic (or ancestral) and how they changed to what new character. The outgroup must be outside the study group, in this case, orchids, which would be the Lily.

Coal is a fossil fuel that is used to produce electricity. Which of these statements best describes a cost of coal mining on the

Darya [45]

The statement that best describes a cost of coal mining on the region around the mines is that Its groundwater is contaminated.

<h3>What is coal mining?</h3>

A coal mine is a mine from which coal ore or coal minerals are mined.

Mining is activity of removing solid valuables from the earth or the activity that extracts or undermines.

Mining is a process that releases pollutants into the environment, therefore, the statement that best describes a cost of coal mining on the region around the mines is that Its groundwater is contaminated.
