Question

Where in a molecule is energy stored?
How does your body get energy out of the food you eat? (Is it basically like your body breaks down the food into simpler molecules that it can use? I don't know of it that's right but my guess)
Why does living organisms release energy gradually?
Is it true that enzymes must be constantly synthesized by the body since they are used up in a reaction? (I thought that enzymes don't react so you don't need more right? I'm not sure. by the way what does synthesize mean?)
where in a cell would you look for dna?
what bases do dna and rna have in common
is dna or rna longer


thanks

Answer 1

1. Energy is stored in the bonds of the molecules.
2. We get energy from the foods by breaking the bonds and making ATP during the process called cellular respiration.
3. Cells use respiration to release energy gradually so it is controlled and won't damage the cell. Just think about cars - they burn a little puff of gasoline at a time to use the energy, not all at once.
4. Enzymes can be used over and over again. They are not changed during a reaction. Synthesize means "made" or "built" or "produced".
5. DNA is in the chromatin or chromosomes in the nucleus of a cell.
6. DNA's bases are adenine, thymine, cytosine, guanine. RNA's bases are adenine, uracil, cytosine, guanine. A,C,G in common.
7. DNA is longer.
