exothermic
they produce more energyy
No, the sun's energy comes from nuclear fusion reactions
The light reactions of photosynthesis produce energy-rich compounds like ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules carry and provide energy for the subsequent dark reactions of photosynthesis.
exothermic, (gives off heat)
The light reactions in photosynthesis capture sunlight to produce energy in the form of ATP and NADPH, which are then used in the dark reactions to convert carbon dioxide into glucose. In other words, the light reactions provide the energy needed for the dark reactions to occur and produce sugar.
Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.

Metabolic reactions produce energy (ATP), which is used by the body for various functions such as growth, repair, and movement. They also produce waste products that need to be eliminated from the body.
Heat is generally considered as a resultant of other energy reactions, which is why it is considered to be related to kinetic energy. All types of energy (the ability to do work) can produce heat energy.
