Cellular Respiration Song: Better Than Revenge

For chapter 3, instead of having a test, we had to create projects explaining the process of Glycolysis, the Krebs Cycle, and the Electron Transport Chain. For the project my partner, Sara, and I decided to make a song. The lyrics go to the beat of Better Than Revenge by Taylor Swift. We also decided to make a power point and Jing the song over it so the viewers will have a better understanding of what we are singing about. In class we did it live because the quality of the recording isn't top-notch. Even so, I hope you still enjoy it! We had a lot of fun writing the lyrics and singing the song!
(The lyrics are posted below if you want to follow along).

Here are the lyrics so you can follow along.

Line 1-
So, I started as a glucose in glycolysis, two ATP came in and gave me their phosphates. I was broken down into PGALS and re-arranged into Pyruvate,  created 4 ATP and 4 NADH.
I was in cytosol, lost a carbon became an acetate. Co-enzyme A brought me into the mitochondria, he left me to join with 4 carbons and become a citrate, this is the beginning of the Krebs Cycle.

Chorus-
I was a glucose I will be broken down into ATP, woah,
My body will use this ATP for energy, woah,
Energy is great, we use it all the time for our bodies to move,
Our bodies are the best, for doing, cellular respiration.

Line 2-
We enter the Krebs Cycle as an acetyl CoA, we were joined by 4 carbons and became a citrate, we lost a carbon and created NADH, we are now a five carbon ketoglutarate.
We will lose another carbon, create NADH, and ATP, now we are a four carbon fumerate.
During re-arrangement become oxiloacetate, create NADH and FADH2.
REPEAT PER PYRUVATE. 

Chorus-
I was a glucose I will be broken down into ATP, woah,
My body will use this ATP for energy, woah,
Energy is great, we use it all the time for our bodies to move,
Our bodies are the best, for doing, cellular respiration.

Line 3-
Use the electrons from previous energy carriers, they go through the cytochromes and pump H+ ions into the inter membrane the high concentration pushes them back into the matrix through the ATP synthase.

Chorus-
I was a glucose I will be broken down into ATP, woah,
My body will use this ATP for energy, woah,
Energy is great, we use it all the time for our bodies to move,
Our bodies are the best, for doing, cellular respiration.

Line 4-
Now I have created 32 ATP using the electron transport system. The NADH and FADH2 gave me their electrons, and the cytochromes brought them through the system. In the end they bonded with oxygen and created water. While chemiosmosis gave me ATP, cellular respiration is the best for giving me energy.

Cybertherapy: "Visual Humans, Real Therapy"


Most everyone has seen a recent movie called Avatar, where people go into a world and become funky blue avatars. However, most people did not know that therapists have been using avatars in therapy for the past ten years. The therapists put people in real life situations, using avatars, to help them get over their fears or phobias. The people can inhabit the avatars as themselves. They can talk to people, which are avatars on a screen; or they can talk to one avatar on a computer whom replaces an actual person as a therapist.

When using the avatars the person knows they are not in a real situation. However, being able to practice and experience a real life situation can be very helpful. The person knows that the worst won't happen, their therapist is there incase he or she freaks out, and the situation feels real. People are drawn to whatever their problem is. If someone is an alcoholic, they will be drawn to a visual bar. If a person is socially awkward then a question by a visual person will scare them. The therapists can help their patients work through whatever triggers their problem. The experiences they have in the visual world, and the things they learn there, carry over into their real lives.

The therapists can control the experience and then work on the response.

A type of cybertherapy is when patients talk to a visual therapist about social issues. The person on the screen is clearly not real. However, he or she has all the qualities a good therapist has. The "therapist" will keep eye contact with whomever they are talking to, and are empathetic to each persons social issues. Talking to this virtual human can be very helpful because studies have shown that people with social anxiety open up more with a visual therapist than they did with real life therapists speaking to them through a computer screen.

There are lots of other methods for lots of other problems. Problems such as social anxiety, returning from war, or children with autism. Scientists are looking for ways to fix these problems using cybertherapy. So far the results have been good. I believe this could be a great way to cure the mental mindset of people with the problems written above, and be a cure for people with dangerous mental mindsets. People with anorexia, bulimia, and others could benefit a lot from cybertherapy. I have great faith that cybertherapy will advance as research continues, and that it will be a great success.

Osmoregulation of Freshwater Fish

Freshwater fish are hypertonic to their water environment, meaning water from the outside diffuses into them through their gills. The gills are permeable to water, but they are also permeable to waste products. Allowing the fish to expel respiratory gasses, ammonia, and ions.

The water flows in through the gills in favor of the osmotic pressure in the blood; while sodium and chloride ions diffuse out of the fishes system into the external environment. These fish have to use energy to regulate the water increase and ion decrease of their bodies.


The fish have special lamellae (dictionary.com: a thin layer, membrane, scale, or platelike tissue or part) in their gills that contain sodium and chloride enzymes. These special enzymes use energy to push sodium and chloride ions up their concentration gradient to keep higher concentration in the fishes body.

The kidneys regulate the large amount of water intake by producing a lot of dilute urine. Even though the kidneys are very helpful in maintaining the high amount of water intake, a lot of salt is lost through the urine and the gills.

It is very important for freshwater fish to have low stress levels and proper nutrition; this keeps them healthy and reduces damage to kidneys. Kidney damage through bacterial infection is detrimental to a fishes life.

Some examples of fish who strive in their native environment are Angelfish and Discus. These two fish have very efficient osmoregulatory systems because of the type of water in the Amazon River Basin. However, when these fish feel stressed their systems are much more likely to fail.

The Organelles That Make Up a Cell in Comparison to My Soccer Team

Our project, this week, was to make a glogster using people, or things in our life as the organelles of a cell to explain each organelles function. I decided to use my soccer team as the different organelles. The organelles that I think are most like the girls on my team is the nucleus, nucleolus, ribosomes, lysosomes, endoplasmic reticulum, vesicles, golgi apparatus, cytoskeleton, and the cell membrane. We were only supposed to chose eight organelles, and I didn't realize until now that I have nine, so I'm sorry about that.


Also, the words in the glog link to other glogs explaining the reason I chose certain people for certain organelles. Just a warning, the links do not go directly over the words, so it can get a little confusing. However, do not give up hope, the link you are looking for is there. It may just take some extra effort to put the mouse in the correct spot.
