Detailed explanation-1: -Non-cyclic photophosphorylation results in the production of ATP, NADPH and O2. O2 thus produced is released in the atmosphere while ATP and NADPH are used during the dark reaction for the synthesis of sugars.

Detailed explanation-2: -In non-cyclic photophosphorylation, the movement of electrons occurs in a non-cyclic manner. In this process, the electrons coming from the photosystem II are excited electrons whose energy is used to produce ATP. The end product of this process is NADPH, oxygen, and ATP.

Detailed explanation-3: -The net result of non-cyclic phosphorylation is the formation of NADPH, oxygen and ATP molecules. Oxygen is produced as a waste product of photosynthesis. In non-cyclic phosphorylation electrons are removed from water and passed through PS-II and PS-I before ending up in NADPH.

Detailed explanation-4: -Non-cyclic phosphorylation is a type of photophosphorylation in which flow of electrons is non-cyclic. It results in the production of ATP and NADPH.

Detailed explanation-5: -Assertion : In case of cyclic photophosphorylation, there is no production of NADPH and oxygen. Reason : As the electron flows cyclically and NADPH is present in sufficient amount in the cell, hence, cyclic photophosphorylation occurs to provide ATP to power other activities in chloroplast.
