Question
Is glycolysis an ancient method for extract energy from molecules?

Answer
I'm not sure what it means for glycolysis to be an "ancient" method for extracting energy from carbohydrates, but it was one of the first to evolve. The more complex process of oxidative phosphorylation developed later, only after glycolysis had come into existence. Even today, some organisms survive exclusively via glycolytic metabolism, even when far more complex methods for extracting energy from carbohydrates have come into existence.

Expertise

I will answer all biology-related questions through the undergraduate level. I will explain unclear concepts and suggest approaches to solving problems, but would prefer not to completely solve homework problems for you. If you are completely stumped on homework, tell me what you already know and I will help you as much as possible. Please do not ask me for ideas on school research projects; part of research is determining a suitable area of investigation, and that's not a task that should be completed by someone else. Please don't simply send me your homework for solutions. If you are having difficulty after you have started an analysis, I will be happy to direct your thinking; in particular, I would prefer to not simply solve pedigrees for students, but I will be happy to assist in solving pedigrees that you have already started. If you don't understand how to analyze a pedigree, I'd highly recommend watching this video, in which a biology professor explains the basic concepts of pedigree analysis: http://www.youtube.com/watch?v=HbIHjsn5cHo

Experience

I have a BS in Bioengineering with a concentration in Chemical Engineering (which included a heavy focus on biology), and have taught biology, biochemistry, and related subjects for some time now.
