Write a three paragraph essay on cellular respiration.Each paragraph should cover one step,in order.Each paragraph should be 3-5
inna [77]

Answer:

Cellular Respiration

As you all know, cellular respiration is one of the, if not the, most important process that goes on in our bodies and other animals' bodies today. Cellular respiration is the process that is opposite from photosynthesis. While plants are taking in carbon dioxide and water to make sugar and oxygen, cellular respiration uses the oxygen and sugar o make carbon dioxide, water and 36 ATP. The three "mini processes" that take place during cellular respiration are glycolysis, oxidative respiration, and the electron transport chain. Fermentation also occurs in some cases where there is no oxygen present.

Glycolysis is the first stage in cellular respiration. It starts with a six-carbon glucose. Then, two ATP come and are converted to two ADP and two phosphates. Those same phosphates are added to the glucose to make a six-carbon glucose phosphate. That is then divided into two 3-carbon sugar phosphates. ADP comes and leaves charged as ATP because of the phosphate. Without the phosphates the process finishes with two 3-carbon piruvates.

If there is no oxygen present after glycolysis, then the next process is fermentation. Fermentation takes the 3-carbon piruvates from glycolysis and adds and electron to them. The result is lactic acid in animals and ethyl alcohol and carbon dioxide from plants, yeast and fungi. Oxygen can then be added back to the lactic acid to form piruvate again.

After glycolysis or after the oxygen is added back to lactic acid from fermentation, the oxidative respiration, also known as the Krebs cycle, takes place. The 3-carbon piruvates are converted to acetyl-CoA. That is then turned into a 6-carbon citrate. After an electron is added to NAD+ to turn it into NADH, a 5-carbon molecule is formed. Then it turns into a 4-carbon molecule which is then recycled.

The electron transport chain is occurring the whole time that cellular respiration is taking place. It starts with a NADH and a FADH2. Electrons and hydrogen ions are added until the final results are NAD and 2H which yields 32ATP and turns O2 into H2O.

Over all there is 2ATP made during glycolysis, 2ATP made during Krebs cycle, and 32ATP made during the electron transport chain for a grand total of 36ATP!!! After all these products are made they are then converted back by photosynthesis and the cycle goes on and on and on.

What is one of the principal chemical compounds that living things use to store energy
arlik [135]

Answer:

<em>ATP</em> or <em>Adenosine triphosphate</em> is the chief compounds which are used by the living things to store energy.

Explanation:

<em>ATP</em> is the compound that captures the chemical energy released through the degradation of food. It <em>stores</em> the captured energy and <em>releases</em> it at the time of need experienced by the organism.

It is made up of adenine, ribose sugar, and a phosphate group. It is produced in a cell organelle called <em>mitochondria</em> through a process called <em>respiration</em>.

The entrance of a microbe into an individual's vascular space has initiated opsonization. How will the health care provider expl
Alexus [3.1K]

Answer:

B) Coating of microbe to aid phagocyte recognition

Explanation:

Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.

The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.

Thus, Option-B is the correct answer.

Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells
