Suppose the interior of the thylakoids of isolated chloroplasts were made acidic and then transferred in the dark to a ph 8 solution. what would be likely to happen?

a. the isolated chloroplasts will make atp
b. the calvin cycle will be activated
c. cyclic photophosphorylation will occur
d. only a and b will occur
e. a, b and c will occur i know the answer is a but why not b or c as well

(A) The isolated chloroplasts will make ATP

Explanation:

The Thylakoid will receive hydrogen from the acid which is pumped across the thylakoid membrane, and the electrochemical proton synthesis of ATP begins in the stroma. Once the chloroplast has been transferred to the dark, high-energy electrons are loaded together with (H+) onto NADP+, converting it to NADPH.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
