A person with a heart problem needs a pacemaker but is unable to pay for it. The person can approach the various social groups like the non-government organisations to put forward a demand for financial assistance. The non-government organisations have funds that have been collected through various individuals or multinational companies or health organisations that participate in donation programmes. They use these to buy the pacemaker for the needy patient.

How do ATP and NAPH connect light dependent and light independent reactions in photosynthesis​
Finger [1]

Answer:

In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.

ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.

Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.
