5.1: Overview of Photosynthesis
These sugar molecules contain the energy that living things need to survive. Figure 5.1.4 5.1. 4: Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen and to produce energy-storing sugar molecules. The complex reactions of photosynthesis can be summarized by the chemical equation shown in Figure 5.1.5 5.1.
What does light energy do to water and carbon dioxide?

To Understand Energy Storage, You Must Understand ELCC
That holds true whether evaluating renewables (like wind and solar) or energy storage. However, the application of ELCC to energy storage is different in one important way. Unlike wind and solar, energy storage is dispatchable. That means that energy storage can discharge electricity to the grid at any time (as long as it''s charged).

The Light-Dependent Reactions of Photosynthesis | Biology I for
Generating an Energy Carrier: ATP. In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
8.4: Using Light Energy to Make Organic Molecules
Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP. After three cycles, a three-carbon molecule of G3P leaves the cycle to become part of a carbohydrate molecule.
The Physics of Light -
When we run electricity through a gas, electrons get knocked loose (gaining energy from the electrical current); when they rejoin the atom, the energy is released as light. This is what happens in neon and mercury lamps. Light made this way tends to have a very complicated spectrum, because the electrons can only have certain energies in the atom.
