Question

Which statements are true?

1. election carriers are located at ribosomes

2. ATP is a commonet 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 respiration

5. ATP is generated by the flow of protons across the cell membrane

a. 2,4,5

b. 1,3,4

c. 2,3,5

d. 1,2,3

Thanks!

Answer 1

Choice A is correct

We know #3 is right because ATP is a SHORT term energy source.  ATP is normally used almost immediately after it is produced.  Thus, we have already eliminated choices B, C and D.

#2 is true.

#4 is true.  Anaerobic organisms undergo anaerobic respiration (they don't use oxygen to produce energy).

#5 is true.  Protons move through the ATP-synthase (against the concentration gradient), which causes ADP and Pi to bond and form ATP.
