Answer:

Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).

Iodine is a cation because it lost one electron. The ion symbol then would be:

I ⁺

So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.

An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).

Iodine gained one electron and the ion symbol would be:

I⁻

So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.

Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).

Sulfur is an anion that gained two electrons with an ion symbol of:

S²⁻

So from the name Sulfur the name will change into "Sulfide" and its name will now be Sulfide ion.

What is your opinion on Global Warming?

PolarNik [594]

My opinion is that EVEN IF there is anything that humans can do to save our species,
we will argue, debate, play politics, bask in absurd conspiracy theories, fritter around,
dilly dally, and totally ignore the urgency before us, until a time when nothing we're able
to do can any longer have any effect. And that's my opinion.

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.

Hello! I have a question and I ask if you can make it a bit detailed. I am struggling to understand the Calvin Cycle in the proc

igomit [66]

Absolutely! The Calvin Cycle is a process that takes place within the stroma of chloroplasts during photosynthesis. This cycle is a light-independent reaction because it does not need sunlight to fully develop. The process is, however, dependent on ATP and NADHP from those light reactions.

If you want a really good study guide for the Calvin Cycle, just follow this link; it helps A LOT!

Shalnov [3]

Cell culture is the method applied by scientists to grown, cells in the laboratory setting to study the cells for particular reasons.

Explanation:

Cell culture is basically a method for survival, reproduction etc which are done under controlled conditions in the space outside the environment. This is also used for data mining.

Purpose: Cell culture is used for propagation of virus

Advantages:

Vaccine production by replication of virus
Detection of viral cell of virus
Convenient easy and economical method

Disadvantages

Maintenance of sterile aseptic conditions.
Increases microbial contamination
Cross contamination takes place
