grayfalcon89 Posted November 16, 2004 Posted November 16, 2004 Hi, I got two questions to ask. I have an answer (which I'm going to post) that I think is a hundred percent right but I just want to be sure. I think I have the concept right but only thing that confuses me is whether I had answered the questions ENOUGH. Here goes: 1. What does "carboyhydrate" means? Write the formula for glucose. Does the formula reflects that glucose is carboyhydrate? Answer: "Carboyhydrate" means carbon and water (I didn't put this but more clearly, carbo is carbon and hydrate is water). The chemical formula for glucose is C_6 H_12 O_6 (Wish I can use something like LaTex). The glucose's formula shows that it's carbohydrate because first, it includes carbon by C_6. Second, for water, H_12 O_6 indicates water by ratio of hydrogen to oxygen in 2:1, which is the same ratio of water. (Maybe the last part is confusing but what i'm trying to say is 12:6 = 2:1 {rather simple mathematical reducing} and that I was what I was trying to do) 2. How are the photosynthesis and respiration connected? Why are they both important to you? Answer: The first part is rather easy. Those two are reverse to each other. For importance, it's because those two processes take sunlight and uses to run our cells. I feel like I need to say more but I just can't. I remember my bio teacher saying, "Photosynthesis takes sunlight and that energy is used to run the cell" and well, the process that lets them to do is respiration so it's basically: Sunlight - Photosynthesis - Different form of energy ex. glucose - Respiration - Running the cell I think I'm right... Or is it just one person's hope?

(Maybe the last part is confusing but what i'm trying to say is 12:6 = 2:1 {rather simple mathematical reducing} and that I was what I was trying to do) Sounds right, the empiracal formula for most every carbohydrate can be expressed as X number of Carbon and Y number of H2O molecules. There may be exceptions, however, so I dont know.

Or is it just one person's hope?[/quote'] Photosynthesis converts light energy into the chemical energy in carbohydrates. Cellular respiration converts these carbohydrates into other molecules (like ATP) that can be used to run the cell.

Primarygun Posted November 17, 2004 Posted November 17, 2004 Is ATP a waste of energy in the energy flow?
Primarygun Posted November 17, 2004 Posted November 17, 2004 Is ATP a waste of energy in the energy flow?
chadn Posted November 17, 2004 Posted November 17, 2004 Is ATP a waste of energy in the energy flow? Oh heck no. ATP is the single most important molecule in metabolism. The breaking of the phosphate bond on ATP releases an immense amount of energy. It is the energy released by these bonds that supply the energy that runs all cellular processes. The entire process of respiration is to produce ATP from sugars.

The breaking of the phosphate bond on ATP releases an immense amount of energy. It is the energy released by these bonds that supply the energy that runs all cellular processes. Just being a stickler here' date=' but i would like to point out that one does NOT get energy by breaking the ATP phosphate bond. In fact, one can [b']never[/b] get energy from breaking a bond. Breaking bonds always requires energy. The way that we get energy out of the reaction is that ATP --> ADP + P and then the ADP and P go to form other products (lets call them products "B") wich are lower in energy that the original ATP. It is this ("B" being lower in energy than ATP) that causes the body to be able to obtain free energy. Well...it is kinda a nit-picky sort of point, but i think it is still important. I don't know how many people (chemists) that i have talk to that belive that breaking the ATP bond actually produces energy. The problem is that we often gloss over the second step and just say that it produces energy. But i think it is important to have a correct conceptual grasp of the mechanisms of chemistry. IN this case, bonds form because they are a lower energy state than the seperate reactants. So energy is given off. Nessesarily, energy must be absorbed, then, when the bond is broken. That is all Yay!

Primarygun Posted November 18, 2004 Posted November 18, 2004 So wastes of energy in energy flow are mainly the ATP from respiration and heat loss,right? What's the difference between heat loss and loss by ATP?

VendingMenace Posted November 18, 2004 Posted November 18, 2004 the difference is that the body can use ATP later on down the road to do something useful. The energy lost to heat is just dissipated and cannot be regained. (though of course it is nessesary to keep your body warm to some degree, so i guess it is not entirely pointless). Think of it this way... Making ATP is like making a battery. It takes energy to make it, but once you have it, you can use it later to something else you might wish to do. Loosing heat is like running the heater in your house with all the doors open. Sure, it will heat your house some, but pretty quickly the heat will escape and you will never again see the energy you put into heating your house. It is totally lost. Does that help?

Primarygun Posted November 19, 2004 Posted November 19, 2004 Yes it really helps. Plants convert light energy into chemical energy stored in form of chemical energy in food. Breaking food liberates some chemical energy and at the higher th consumer cannot take in. Energy is loss in food chain. Is it?

chadn Posted November 19, 2004 Posted November 19, 2004 Energy is loss in food chain. Is it? Yes, the food chain involves numerous chemical reactions and transfers of energy. Each time energy gets converted to one form or another, or is transfered in some way some of its going to get lost. Its called Entropy. Now there are many finer details that I have not mentioned, but that the gist of it, without writing a whole book.
