When NADH is the electron donor to the respiratory chain, 2.5 ATP are formed, but when FADH2 is the electron donor, only 1.5 ATP
Fofino [41]

Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.

Explanation:

Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.

NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.

While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.

So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it
