Since both glycolysis and gluconeogenesis are irreversible processes, there is no thermodynamic barrier to their simultaneous op

eration. However, it is important for the cell not to run both glycolysis and gluconeogenesis at high rates simultaneously. Which of the following is a reason for this?
a. More pyruvate is consumed in one round of gluconeogenesis than is produced in one round of glycolysis.
b. A net loss of 2 ATP would occur for each simultaneous round of glycolysis and gluconeogenesis.
c. A net loss of 4 ATP would occur for each simultaneous round of glycolysis and gluconeogenesis.
d. Both the first and second answers are correct.
e. Both the first and third answers are correct.

Answer:C

Explanation:

It is important for the cell not to activate glycolysis and gluconeogenesis at high rate simultaneously because it is expensive for the cell.

In the break down of one molecule of glucose to pyruvate, one ATP is used in the conversion of glucose to glucose-6-phosphate and one ATP is used in the conversion of fructose-1-phoshate to fructose-1,6-biphosohate. While a total of four ATPs are produced.

Making it a net gain of 2 ATP in glycolysis.

Gluconeogenesis  produces no ATP and requires equivalents of 6 ATP (4 ATP and 2GTP) for one molecule of glucose produced.

(Glycolysis +2ATP) + (gluconeogenesis -6ATP) = -4ATP

There's a net loss of 4ATP if both reactions are activated simultaneously.

In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8

Dafna11 [192]

Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "

The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.

Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.

Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.

Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.
