The first step in photosynthesis involves light reaction. what are the products of these reactions

Light dependent reaction is the first stage of photosynthesis, this reaction occurs on the thylakoid membrane, the inner part of chloroplast.  On this stage, light energy is transform to a chemical energy called ATP (adenosine triphosphate and a reducing power called NADPH (nicotinamide adenine dinucleotide phosphate). ATP and NADPH are the products in the first stage of photosynthesis.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
