What are the steps of cellular respiration?

1 answer:

7 0

<span>In chronological order, the four steps of cellular respiration are glycolysis, a transition reaction, the Krebs Cycle and an electron transport chain. Cellular respiration occurs in the cytoplasm and in the mitochondria.

</span><span>Glycolysis occurs in the cytoplasm, and it allows one glucose molecule to split into two molecules of pyruvic acid. Next, the transition reaction moves the pyruvic acid into the mitochondria, where it is converted into acetyl coenzyme A. Next, the Krebs Cycle occurs in the mitochondria and produces four molecules of ammonium triphosphate and numerous molecules of reduced nicotinamide adenine dinucleotide. Finally, the electron transport chain in the mitochondria produces approximately 32 molecules of ATP and finishes the process of cellular respiration. In total, approximately 38 molecules of ATP are produced for every molecule of glucose.</span>

Nutrition absorbed by the capillaries of the small intestine travels first to the liver. how does that happen?

Sladkaya [172]

The portal vein directs blood from the GI tract to the liver. The liver is the first organ to receive nutrients that are absorbed from the GI tract. It is the ‘gatekeeper’ and is responsible for filtering out possible toxins before they reach delicate tissues such as the brain.

Answer:

Sample A

T= 21.3% and A= 21.3%

G=28.7% and C= 28.7%

SAMPLE B

T=28.7% and A= 28.7%

G= 21.3% and C= 21.3%

Sample A would have higher melting temperature

Explanation:

According to given information, sample A contains 21.3% thymine.

Percentage of adenine in sample A= 21.3% (Since adenine base pairs with thymine, so, adenine and thymine are present in equal amount in a double stranded DNA)

Total of A+T in sample A= 21.3 + 21.3 = 42.6%

G+ C content of sample A= 100-42.6= 57.4%

Percent G content of sample A = 57.4/2 = 28.7%

Percent C content of sample A = 28.7%

SAMPLE B:

According to the given information, sample B contains 28.7% thymine.

Therefore, percent of Adenine base in sample B= 28.7%

Total of A+T content in sample B= 28.7 + 28.7 = 57.4%

G + C content of the sample B = 100-57.4= 42.6%

Percent G content of the sample B= 42.6/2= 21.3%

Percent C content of sample B = 21.3%

There are three hydrogen bonds between a GC pair while there are only two hydrogen bonds between AT pair. The DNA content with higher GC content has higher melting temperature. Therefore, sample A would have higher melting temperature.

Answer:

Is C

Explanation:

In translation, the cell uses the genetic information contained in mRNA to make the proteins that

carry out the cell’s work. The cell translates the code contained in the mRNA into a new

language, the language of proteins, based on amino acids. Other types of RNA, such as transfer

In this section, you will be introduced to the components involved in the process of protein

synthesis, called translation. This process requires a protein/RNA complex called the ribosome

Which data are MOST useful for analyzing the climate of the region?

Kipish [7]

Answer:

The correct answer is - option D.

Explanation:

According to some scientists, a climate of a region is an average of the weather for a specific region for a particular period, which is more often 30 years or over.

SO, according to the options and the given information above, the measuring average temperature for 30 years of the month of July is most helpful in analyzing the climate of a specific region.
