ATP and food

[leatherface]

Ok, just curious... I know that ATP is what gives your body energy. Actually the energy comes from the break down of ATP into ADP, and then its 'regenerated' when CP(creatine phosphate) forms with ADP to remake ATP. Now im curious where food comes into play here. I know that food gives you energy, but is that a different kind of energy, or does food like Make ATP or something? I think thats understandable So if anyone knows anything about this then post!!! lol thanks

The energy that fuels you comes from the chemical bonds of carbs, fats, and proteins. Let me back up to before the food is food for a sec. Originally, the energy from food is a product of photosynthesis. Plants use energy from the sun to produce glucose (among other things). They trap solar energy that is generated from sharing electrons in chemical bonds. So photosynthesis yields compounds with MORE energy contained in the chemical bonds of the products than the building blocks (carbon dioxide and water). The energy for this uphill process comes from the sun. Your body transforms the electrical energy found in carbs, fats, proteins, into other forms

1. Chemical energy to transform carbs
2. Mechanical energy to move muscles
3. Electrical energy to drive nerves
4. Osmotic energy to maintain ion balance between cells

Guess what the byproducts of this are? Yep...carbon dioxide and water (which are the building blocks of the plant). See the connection? Now you know the circle of life.

The function of your metabolism is to take these chemical bonds from your food, and convert them into something you can use...one of those things being ATP.

In carb metabolism, it all starts with Glycolysis. There are two ways to make ATP. Either fuel molecules supply the energy OR trapping light energy by means of photosynthesis. As humans, we can obviously only do the first. The carbs you eat get converted, eventually, to Glucose...the most simple of all sugars. Through the process of glycolysis (breaking down glucose), your body uses glucose and existing ATP to spark further processes and yield other molecules to make energy. Your body uses 2 ATP to GO THROUGH glycolysis (the process itself has to be fueled), and then it MAKES 4 ATP. 4 ATP made, 2 ATP used to make them, yields 2 ATP total. This is all from one molecule of glucose.

So that's how it goes from the garden, to the animal, to your plate, to your body, and so on...

Does that answer your question?

Pretty much Thanks.. I had 1 other question but that post was deleted so....

I read somewhere that when pitching(like in baseball) your bicep was the Agonist muscle and your tricep was the antagonist. But the Tricep is the muscle that straightens out the elbow, so shouldn't it be the Agonist? I know that it is when you are punching so I would think it would be the same. And while im on it, does anyone know what muscles would be the Agonist and which would be the Antagonist for different fighting techniques like a hook, cross, sidekick, hook kick? Thanks a ton like always!@

Which arm are you talking about? When you swing a bat, isn't one arm pushing while the other is pulling? Wouldn't that reverse the agonist/antagonist based on action?

lol I can't think of a single muscle group that isn't somehow involved in pitching. Any good pitcher will use any and all muscles available to impart force to that ball. In terms of upper body, seems like it'd be triceps, pecs, ...that...internal rotatie thingie (opposite of rotator cuff), and trunk muscles.

Ya i undestand that like all muscles are used when pitching or punching or anything, i was just curious about that antagonist/agonist thing. So your saying you would think the tris or chest would be the agonist huh?

Yeah...Oh, I also forgot the lats. Think about the motion for a sec...you start out with your arm high and bring it down across your body while simultaneously extending it.

So you have elbow extension (triceps),
transverse adduction (chest, flye is a good example)
Adduction (Lats, think pullover)
and finally a twisting of the trunk (obliques)
