7. what is the main purpose of translation?
a. create a polypeptide strand directly from a dna strand
b. use the mrna strand as a template to bring in the appropriate amino acid strands to build a protein
c. use the trna strand to build rrna to make proteins
d. create an mrna strand from a dna template strand

The answer is B and I suggest you to go for that !

for any info, comment !

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
