<span>Hydrogen bonds do not form in all molecules because hydrogen can only form these bonds with highly electronegative atoms. It is a weak type of force that happens when a hydrogen atom is bonded to an atom which has a high electronegativity. For water, it is present because hydrogen is bonded to oxygen which is very electronegative.</span>

Why do organisms without oxygen need to convert pyruvate to lactate?
IrinaK [193]

The question is incomplete. The complete question is:

Question: Why do organisms without oxygen need to convert pyruvate to lactate?

A) because pyruvate is toxic to the cells

B) in order to regenerate NAD+

C) in order to use lactate in the citric acid cycle

D) because lactate is needed to produce ATP

Answer:

B) in order to regenerate NAD+

Explanation:

Kreb's cycle and electron transport chain (ETC) are the aerobic stages of cellular respiration. ETC regenerates NAD+ and FAD+ by oxidation of NADH and FADH2 produced during glycolysis and Kreb's cycle. Here, oxygen serves as the terminal electron acceptor.

Glycolytic reactions use NAD+ as an electron acceptor and produce NADH. Therefore, a constant supply of NAD+ is required to sustain glycolysis. In absence of oxygen, ETC cannot occur and organisms convert pyruvate into lactate. Pyruvate is reduced in lactate and NADH serves as the electron donor. Thereby, lactate fermentation regenerates NAD+ to continue the process of glycolysis.

Please help me I don’t understand it.
Irina18 [472]

Answer:

1) bay - 0%

  cream - 0%

  buckskin - 100%

2) cream - 25%

    bay - 25%

   buckskin - 50%

3) co-dominance

Explanation:

Ok so a run down on Punnett Squares,  all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture.  Now, co-dominance, this basically means that there is no dominant allele.  For example, imagine a white flower (W) and a red flower (R).  If these two plants were to breed, you would get a pink flower (WR).  This means the red allele and the white allele are both co-dominant.  It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink.  This is also how you get an AB blood type.

I hope this helps!
