After glycolysis occurs, the products may enter the Krebs cycle. Which major products result from these reactions?
ivolga24 [154]

The third option from top is the answer. The major products that result from the Krebs cycle are NADH,  FADH and ATP in that order.

The Krebs cycle is the central metabolic pathway in all aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion. These reactions take a two carbon molecule called acetate and completely oxidize it to carbon dioxide.

The Krebs cycle serves two main purposes namely:

1.To increase the cell's ATP producing potential by generating  reduced electron carriers such as NADH and reduced ubiquinone.

2. To provide the cell with a variety of metabolic precursors.

By the time the eight reactions in Krebs cycle are over, one ATP, one FADH and four NADH molecules will have been produced

EastWind [94]

Answer:

Gene is present on the X chromosome.

Explanation:

The two main types of chromosomes are autosomes and sex chromosomes. Autosomes regulates the functioning of the body but do not play role in determining the sex of an individual. The sex chromosomes distinguishes between the male and female.

The linkage of sex chromosomes is present in Drosophila as well. The cross between the F1 generation leads to both the red and white eyed flies because the eye color gene is present on the X chromosome. The males contain only one X chromosome and the presence of recessive gene results in the white color whereas in females both the X chromosomes must contain recessive gene for the white color.  

Thus, the answer is gene involved is on the X chromosome.
