Photosynthesis is divided into light-phase and the dark-phase. The former occurs in the presence of sunlight while the latter is independent of sunlight.
Explanation:
The light-dependent phase begins the process of photosynthesis. The energy of the sun is used to split a water molecule into H+ and O- in a process called photolysis. IN the process, two high energy electrons are released and used to replace the ones that left the reaction system of the chlorophyll pigments. The electrons being replaced were conveyed through a protein chain and their energy used to pump H+ ions into the thylakoid from the stroma. The electrons are ultimately used to reduce NADP+ into NADPH. This creates a proton motive force used by ATP synthase to create ATPs – a process called photophosphorylation.
IN the light-independent phase, carbon dioxide is reduced by NADPH to create glucose molecules in the Calvin cycle.

Cellular respiration involves the complete breakdown of glucose to carbon dioxide and water
When sodium chloride is formed from a positively charged sodium atom and a negatively charged chlorine atom, the charge on the salt becomes neutral is true
Explanation
Sodium ion ( positively charged) combine with chloride ion ( negatively charged) to sodium chloride which is neural according to equation below.
Na⁺ + Cl⁻ → NaCl (<em>neutral</em>)
Equal number of positive and negative charges add up to make neutral Nacl therefore the statement above is true.
