How many atp molecules are added to get glycolysis started

romanna [79]

Answer:

2 ATP

Explanation:

2 ATP is required to get the glycolysis started. The glycolysis process is divided into two parts, the first part is called the preparatory phase in which energy is required and the second part is called the payoff phase in which energy is produced.

During the first phase in the first step during the conversion of glucose to glucose six phosphate one ATP is consumed and in the third step during the conversion of fructose 6 phosphate to fructose 1,6 biphosphate one more ATP is consumed and in the second phase, 4 ATP is produced.

Therefore the net gain is 2 ATP because 2 ATP are added to get glycolysis started.

levacccp [35]

Answer: Hypothalamus

The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.

Explanation:

Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:

- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics

- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.

Thus, hypothalamus plays important role in puberty

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.
