Question

1. Which of the following membranes should ATP be able to cross?

a. nuclear membrane (via nuclear pore complex)

b. chloroplast inner and outer membrane

c. mitochondria inner and outer membrane

d. a & b

e. a & c

f. b & c

g. any of these

Answer 1

any of these

The nucleus, chloroplast, mitochondria requires ATP for many of the cellular processes. In the nucleus ATP is required for DNA replication , repair, chromatin remodelling. In the mitochondria, ATP is produced and sent to other parts of the cell where energy is required through transport molecules. In plants, ATP is produced in chlorplasts through photosynthesis and transported to other organelles.

SO ATP should be able to cross these membranes.
