Atp synthase complex is found:
a. thylakoid membrane of the chloroplast
b. stroma of the chloroplast
c. matrix of the mitochondria
d. outer membrane of the mitochondria

The correct answer will be option-A.

Explanation:

ATP synthase is an enzyme complex made up of two regions called F₀ and F₁ cells.  The complex helps in the production of ATP molecules which provides energy to the cell.

The ATP synthase is found in the thylakoid membrane of the chloroplast and inner membrane of the mitochondria The F₀  particle is embedded in the membrane while F₁ particle faces matrix in mitochondria and stroma in the chloroplast.

Thus, option-A is the correct answer.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
