About John Locke
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.

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.

Education/Credentials
BS Bioengineering, Penn State University MCAT/DAT/OAT Instructor

Question
What 'M' is the mainly found in the body paet of the sperm?

Answer
I suspect the "M" you're describing is mitochondria, which are present in high concentrations within the body of sperm cells. Mitochondria are small organelles that produce ATP, which is a molecule that acts as the major energy source for cells. Sperm have to use a lot of energy when swimming, so they require lots of mitochondria to get around. For more information, see the link below:
