Answer:

D

Explanation:

I believe its D because we cross out the first 2 options because the question is asking about the dark line which is the pups and not the adults. if we look D and the lowest point of dark line, we can say its talking about <u>few</u> and 1995 talking about <u>many. </u>

Bruce has a genetic disorder. bruce and his wife, kim, have three children, one of which has the genetic disorder. how is this d
laiz [17]
This would be a recessive disease.

Father is dd
Mother is Dd (has to be because one child has the disease)

Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!

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.
