This week I learned the order and basic process of cellular respiration. I'm still having trouble memorizing the reactants and products of each step.
This week I have learned that glycolysis breaks down glucose into two pryruvate molecules. I still need help with understanding what fermentation is.
This week I learned about cellular respiration and the concepts of it. I still need help with understanding what is exactly involved in it.
This week I have learned about cellular respiration, and how and where it occurs. I am having trouble with the order of the processes and how exactly each of them works; what is involved in each of the processes we learned about?
Maddi2, in fermentation, the pyruvic acid molecules are turned into some kind of waste product and it also creates 2 ATP molecules per one molecule of glucose. The two most common types of fermentation are lactic acid fermentation and alcahol fermentation. Fermentation is used when one goes into oxygen debt or is exercising anaerobically. When the body cannot produce enough oxygen to make energy, fermentation steps in and uses pyruvate instead. Fermentation only makes a few ATP, but it is better than nothing.
This week i learned about cellular respiration and what is put out from it.I still need help in the order that cellular respiration goes in.

This week I learned that glycolysis is the splitting of a 6-C sugar into two 3-C sugars and the remaining atoms form two pyruvate molecules. I still need help with understanding how cellular respiration works exactly.
This week I learned about the citric acid cycle and its role in oxidizing organic molecules.I still need help with the production of ATP.
mrgn1517, cellular respiration involves many things.It involves glucose,NADH,the electron transport chain,protonmotive force, as well as, ATP.The three most important areas are glycolysis, the citric acid cycle, and the electron transport chain.All of this fuels oxidative phosphorylation. Four ATP are manufactured directly from phosphorylation.Every NADH that transfers electrons to the ETC gives to the protonmotive force what it needs to create a possible 3 ATP.This is the basic idea of cellular respiration.
This week I learned about cellular respiration. I learned that glycolysis breaks down glucose in the cytoplasm. The citric acid cycle happens in the mitochondria. I am still a little confused with fermentation.
Jerrod cellular respiration goes in the following order: glycolysis, citric acid cycle, and electron transport chain.
This week I learned the workings of the three processes that make up cellular respirtaion. I still need help with the conversions and chemicals used in the cirtic acid cycle.
Kasey, fermentation uses pyruvate generated from glycolosis to regenerate the enzyme NAD+ to further the glycolosis production. The pyruvate is changed using NADH in such a way that the NADH molecule reverts to NAD+ and then, is reused in the glycolisis step.
This week i learned the difference between cellular respiration and fermation.
I still need help with the reactants and products for each step of cellular respriation.
This week I learned about cellular respiration and the location that it occurs in. i still need help memorizing everything that cellular respiration is about. Also thanks for reminding me maddi2 about glycolysis.
paas, cellular respriation produces the ATP needed for cells to do work.

This week i learned about the respiration in the cell. As well as what it produces during the process itself.
The only issue i am having is memorizing the correct order of the steps in said process.
Maddi fermentation is a catabolic process that puts out a limited amount of ATP from glucose without an ETC and produces an end product such as ethyl alcohol or latic acid

Over the past week, I have learned that the electron transport chain occurs in the membrane of the mitochondria, and glycolysis occurs in the cytoplasm. I have also learned that NAD+ and FAD are enzymes active during cellular respiration. I am still having trouble understanding exactly what pyruvate is.
Sara, the way you could remember the order would be to remember GCE, which is an acronym I made up. Since glucose is involved in cellular respiration, think about the order that the letters g, c, and e are in in the word glucose. G would be first, and that would stand for the first stage of cellular respiration, which is glycolysis. The next letter in GCE would be c, and that stands for citric acid cycle (2nd stage). Also, the last letter in that acronym and in the actual word glucose is e, which stands for electron transport chain (3rd and final stage). I hope that helps you like it has me!
jenna, when glycolysis begins the degradation process by breaking glucose into two molecules of a compound, this is pyruvate. and in the citric acid cycle, that completes the breakdown of glucose, a derivative of the pyruvate that has just been produced is made into carbon dioxide :)
This week I learned that cellular respiration has 4 steps, it starts with glycosis, then the transition reaction, followed by the citric acid cycle then lastly the Electron Transport Chain. I'm still having trouble with memorizing the different reactants and products of each step.
this week i've learned about cellular respiration, which kim i can help you out with! cellular respiration is when is the set of metabolic reactions and also when processes take place in organisms' cells to convert biochemical energy from nutrients to ATP and then release waste products.

This week in Dc bio I learned about cellular respiration and how it occurs. I still need help with the order it goes in and fermintaion.
stephanie, cellular respirtaion goes in a process of three metabolic stages: glycolysis, the citric acid cycle, and oxidative phosphorylation (includes ETC & chemiosmosis). Fermentation is the partial breaking down of sugars without using oxygen.
