Which of the following statements are true?
1. electron carriers are located at ribosomes
2. atp is a common intermediate between catabolic and anabolic pathways
3. atp is used for the long-term storage of energy and so is often found in storage granules
4. anaerobic organisms are capable of generating atp via respiration
5. atp can be generated by the flow of protons across protein channels

a. 1, 3, 4
b. 1, 2, 3
c. 2, 3, 5
d. 2, 4, 5
e. all of the statements are true

i'd say that the moon rock is about 2.2 billion years old.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
