It is one of the four building blocks for DNA synthesis. It provides energy coupling between exergonic and endergonic reactions. Its hydrolysis provides an input of free energy for exergonic reactions. Its terminal phosphate bond has higher energy than the other two. Its terminal phosphate group contains a strong covalent bond that, when hydrolyzed, releases free energy. SIA iction green and yellow Where does the Calvin cycle take place? cytoplasm surrounding the chloroplast interior of the thylakoid (thylakoid E. lumen) stroma of the chloroplast thylakoid membrane outer membrane of the chloroplast B.

Answer 1

30. E- cell to cell recognition.

(the main function of these are cellular recognition in cell membrane.)

32. B. It provides energy coupling between exergonic and endergonic reaction.

(by exergonic reaction hydrolysis of ATP to ADP and Pi with endergonic reaction.)

35. c. Stroma of chloroplast.

(Calvin cycle or C3 occurs in stroma of chloroplast of photosynthetic organism.)
