Actin/Myosin Filament & ATP - Personal Trainer Community - Forum

[jackson]

Do I need to know more about Actin/Myosin Filament beyond the fact that actin is thin, myosin is thick and binds to actin and this process depending upon the direction in which all the myosin are bending lead to muscle contractions.

Do I have this right and is this sufficient knowledge for the exam or do I need to know this more in-depth? Please enlighten my understanding if I have any of this incorrect.

As for the ATP do I need to know more than the fact that ATP functions as a way to transport energy within cells for metabolism? ATP is an energy transfer molecule in cells.

Do I need more in-depth knowledge?

Help, please...

Thanks,

JAXX, Buddy.

Something that someone explained to me a long time ago when I was sitting for certification exams is this:

"Certification Exams are Geared For Passing" Which means, the certifying agency, while they want to make sure you have a good grasp of the concepts and knowledge are not going to make the exam impossible with trick questions or require you to know knowledge that isn't presented in the Text Book.

It's in the certifying agency's best interest to pass as many test takers as possible, so they can have high enrollment and lots of due paying members.

So where as college professors may create exams that are difficult to pass or include tricky questions these test do not.

If you've been taking the practice exam and studying the text you'll do fine. (Barring any test taking anxiety you may suffer from the actual day of the test).

Good LUck!

I guess from what youre saying Dave and what Christina has also said to me perhaps Im worrying too much. Im so afraid of failing thats all.

Its been so long since Ive had to take any sort of major exam based on academics that my confidence level is extremely low. Plus I need so badly to pass that puts added pressure to be sure Im ok with this info.

I appreciate this group here though because you all have helped in various ways and increased my own personal esteem.

With that being said, Dave you never really stated if what I said about actin/myosin and ATP was accurate.

Thanks,

Jaxx,

Yes, I really do believe you need to know more than which one is thick and which is thin. But also, what stimulates them and why?? What is their role in contraction?

And, as far as ATP goes, where is it made? And, again, why? What will deplete it most quickly and is it aerobic or anaerobic metabolism? What happens when we're depleted of ATP??

I think you're missing major pieces, myself.

I was part of a workgroup revising a certification exam for one of the major organizations, and what we did to write test questions is we would find resources that specifically answered the questions we came up with. However, the key was that you could find the answer to the questions in the resources recommended for studying for the exam. The book we were going to refer to hadn't been written yet, but all of our questions had to be referenced so these parts could be included. So, to answer your question, make sure you learn all you can from the recommended resources and you should be fine. As long as you understand what you're learning (memorizing).
