The genotype is your total heritable hereditary character; it is your one of a kind genome that would be uncovered by individual genome sequencing. In any case, the word genotype can likewise allude just to a specific quality or set of qualities conveyed by a person. For instance, in the event that you convey a change that is connected to diabetes, you may allude to your genotype just as for this transformation without thought of the various quality variations that you may convey.

Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons f
denis23 [38]

Answer:

from glycolysis to electron transport.-glycolytic pathway

NADH  and FADH2 are the major electron carrier   from glycolysis through the Kreb Cycle to the electron transport chain.

Note-NADH  alone transports electron  from glycolysis  to the Kreb Cycle. while both   NADH and FADH2  transport electrons   from the kreb'cycle  to the electron transport chain.

from citric ac id cycle to the electron transport chain.

as explained above both NADH and FADH2.

The electrons are  in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial

Note.

Nicotinamide Adenine Di nucleotide Hydrogen(NADH)

Flavin Adenine Dinucleotide Hydrogen(FADH)
