Help Please

Hello(: I'm currently working on a science fair project and have ran into a problem. I cannot find an official balanced equation for the formation of lactic acid anaerobic fermentation. I need to answer this question having to do with the Kimchi Chemistry project that ScienceBuddies has posted. If any one knows the equation, I would be super thankful to know it.

Hi california-chill,

In the lactic acid fermentation process, one molecule of glucose (a six carbon sugar) is converted to two molecules of lactic acid. Note that lactic acid has three carbons, so the reaction splits the glucose molecule in half. The following link shows the equation for the reaction:

There are intermediate reaction steps involved in getting from glucose to lactic acid. Some of the chemistry and other background information is shown at this site:

I hope this helps and good luck with your project. Please post again if you haver more questions.

Hello could anyone please help,

I would be so grateful if someone could please help me with the following questions please:

1. How physics is involved in PET scans?
2. Types of radiation it consists of (in PET scans),
3. And risks and benefits of PET Scans.

Thank you so much
