Answer:

The correct answer is C  the extraction of high energy electrons remaining from glycolysis and citric acid cycle .

Explanation:

Electron transport chain(ETC)  occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.

            The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.

Zielflug [23.3K]

Explanation:

Its was discovered back in the 1920s, by Dr. Ralph DeBerardinis and Dr. Joshua Rabinowitz that cancer cells prefer not to rely on the citric acid cycle like healthy cells do. Instead, they turn most of their pyruvate (SALT) into lactate, which then releases. Because cancer cells consume so much glucose, they end up producing a lot of lactate.

In rabbits, black fur is dominant to white fur.
Fudgin [204]

Crossing a BB male with a Bb female:

The Punnett Square will look like this:

BB BB

Bb Bb

The percentage will be as follows:

- You will have 50% homozygous dominant (BB)

- You will have 50% heterozygous (Bb)

Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.

For the genotype, you have 50% BB and 50% Bb

Blood does not enter or leave the ventricles during the period called
babymother [125]
That would be D. Isovolumic contraction

As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.

I can explain the process more if u want in the comments:)

Which best describes the cell theory
Neko [114]
Each cell is alive even if it is part of a multi celled body, and all living organisms consist of one or more cells. Also, cells reproduce by dividing so it follows that all existing cells must have arisen by division of other cells. As a cell divides it passes it hereditary material- its DNA- to offspring.

When cells perform photosynthesis, they transform energy from one form to another, what takes place during photosynthesis?
Oxana [17]

During photosynthesis, solar/light energy from the sun is transformed into C6H12O6, or glucose (chemical energy). Photosynthesis is defined as the process by which green plants and some other organisms use sunlight to synthesize foods (glucose) from carbon dioxide (CO2) and water (H20). Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen (O2) and glucose.
