Why is pyruvate imported from the cytoplasm into the mitochondrial matrix?
grin007 [14]

Answer:

So that oxidation of pyruvate can take place in mitochondria.

Explanation:

Pyruvates is produced in the glycolysis process which occurs in the cytoplasm. So pyruvate is produced in the cytoplasm of the cell. Pyruvate is produced by partial oxidation of glucose and to be fully oxidized it has to enter in the mitochondria.

So after entering the mitochondria the pyruvate first converts into acetyl CoA than this acetyl CoA enters in the citric acid cycle and fully oxidized into CO2. This oxidation generated NADP and FADH2 which provide reducing power during oxidative phosphorylation.

A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight g
madam [21]

Answer:

The correct answer is - 11.25

Explanation:

Given:

Average weight gain between weeks 2 and 4 = 10 grams

The narrow-sense heritability of the weight gain between 2 and 4 weeks

= 25%

Then

Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-

by the formula:

Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )

= 10 + 0.25 (15-10)

 = 10 + 0.25 (5)

= 10 + 1.25

  = 11.25

Thus, the correct answer is - 11.25
