Full Answer
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.
The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process. In the first stage, light energy is captured and converted to chemical energy.

Where do the high energy electrons carried by NADPH come from? The high energy electrons were produced by light absorbtion in chlorophyll to chemical reactions elsewhere in the cell. What are the reactants of the photosynthesis reaction? The reactions are carbon dioxide and water.
So in summary, there are two main roles of NADPH and ATP: (1) they tie the light dependent reactions and the light independent reactions together and (2) they act as sources of energy to take the energy from the sun to the light independent reactions to make the plants food.
Glucose and oxygen are the final products of photosynthesis.
chlorophyllWithin the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.
Photosynthesis in plants is of 3 steps, occurring in chloroplast: Absorption of light, Conversion of light energy into chemical energy and splitting of water molecules, Carbon dioxide is reduced to carbohydrates.
Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules. ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups.
In photosynthesis energy is transferred to ATP in the light-dependent stage and the ATP is utilised during synthesis in the light-independent stage.
Plants fix atmospheric carbon dioxide to store energy in the form of carbohydrates. Carbon dioxide is assimilated in the dark reaction of photosynthesis. During Carbon fixation, CO2 is utilised in the carboxylation of ribulose bisphosphate (RuBP).
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2 is transferred to ATP. During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space.
High-energy electrons are passed to the electron carrier NAD+, forming two molecules of NADH.
High-energy electrons from NADH and FADH2 are passed along the electron transport chain from one carrier protein to the next. At the end of the chain, an enzyme combines these electrons with hydrogen ions and oxygen to form water.
Chlorophyll which is a molecule in chloroplasts. The absorbed energy is then made into sugars.
Cellular respiration is called an aerobic process, because it needs oxygen/carbon dioxide to take place.
Absorbed during photosynthesis. There is a double membrane that has photosystems 2 and 1 inside the thylakoid membrane. Chlorophyll A and B is in the thylakoid and they absorb the sun. The energy gets transferred to electrons that capture the energy and transport it to proteins in the membrane. 6H2O + 6CO2 --- 6C6H12O6 Carbohydrates. It depends on the type of molecule broken down for energy.
ADP has two phosphate groups and ATP has three phosphate groups. When the ATP is broken down, you have phosphate groups that release energy and it converts it into ADP. The electron transport chain is where ATP is produced (in the inner membrane of mitochondria.) ATP carries chemical energy that cells can use.
