Luba_88 [7]
Since you forgot to put capital letters i assume it's like this:

1)A <span>Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).

</span><span> 2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400

</span>The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:<span>YyLl and yyll,
</span>The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.

answer: Yyll and yyLl

I have mutant cells that make no pfk2enzyme. i measure rates of oxygen consumption in these mutant cells and compare them to wil
Kazeer [188]

The correct answer is that mutant cells will exhibit diminished oxygen consumption; decreased glycolysis results in decreased Kreb's cycle and electron transport chain.

The PFK2 enzyme catalyzes the generation of F26BP, this binds with the allosteric site of PFK-1 and increases the affinity of PFK-1 with F6P and also decreases the affinity of allosteric inhibitors citrate and ATP to PFK-1. Thus, PFK-1 will combine with F6P at a greater rate.

This ultimately results in more glycolysis, thus, more ETC and more consumption of O2. If there is no PFK2, then there will be a reduction in glycolysis, TCA, ETC, and consumption of oxygen.

The PFK2 is an enzyme accountable for monitoring the rates of gluconeogenesis and glycolysis in the human body. In the absence of glycolysis, there will be a reduction in TCA, ETC, and consumption of O2.
