How do photosynthesis and cellular respiration relate? …

These Teacher Notes summarize basic concepts and information related to energy, ATP, cellular respiration, and photosynthesis. These Teacher Notes also review common misconceptions and suggest a sequence of learning activities designed to develop student understanding of important concepts and overcome any misconceptions.

How are photosynthesis and cellular respiration related to each other

The products of cellular respiration are the reactants of photosynthesis.

The fact that both resort to the 'electron transport chain' when it comes to the movement of electrons is perhaps one of the most prominent similarities between photosynthesis and cellular respiration.

The photosynthesis-cellular respiration relationship also explains why the two are necessary for the presence of life on the planet.

How are respiration and photosynthesis related to each other

In other words, the plants and other lifeforms which resort to photosynthesis are dependent on organisms which resort to cellular respiration for carbon dioxide, and all these organisms are - in turn, dependent on the glucose that they derive from plants for their energy requirements.


Photosynthesis and Cellular Respiration - SlideShare

The chemical equation for photosynthesis is 6CO2 + 6H2O + Light energy → C6H12O6 + 6O2; wherein carbon dioxide (CO2), water (H2O) and sunlight are reactants and glucose (C6H12O6) and oxygen (O2) are the .

Cellular Respiration: In the process of cellular respiration, the biochemical energy derived from nutrients is converted to adenosine triphosphate (ATP), which is necessary for these organisms to facilitate various life functions.

Photosynthesis and Cellular Respiration - Homework Set

NAD+ and FAD act like electron shuttle buses for the cell. The empty buses, NAD+ and FAD, drive up to oxidation reactions and collect electron passengers. When the electrons get on the bus, the driver puts up the H sign to show that the bus is full. Then the full buses, NADH and FADH2, drive over to reactions that need electrons and let the passengers off. The buses are now empty again, so they drive back to another oxidation reaction to collect new passengers. During cellular respiration, the electron shuttle buses drive a loop between the reactions of glycolysis and the Krebs cycle (where they pick up passengers) to the electron transport chain (where they drop off passengers).

How are photosynthesis and cellular respiration related

Three separate pathways combine to form the process of cellular respiration. The first two, glycolysis and the Krebs cycle, break down food molecules. The third pathway, oxidative phosphorylation, transfers the energy from the food molecules to ATP. Here are the basics of how cellular respiration works:

How are photosynthesis and respiration related

Cellular respiration is also important in the movement of matter through living systems: As living things break down food molecules using cellular respiration, they release the atoms from the food molecules back out into the environment as carbon dioxide and water. Photosynthesis brings in carbon dioxide and water from the environment, and cellular respiration sends them out again, forming a circular matter pathway that scientists call the carbon cycle.

Comparison chart Photosynthesis vs Cellular Respiration ..

The chemical equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy released (2830 kJ mol-1); wherein glucose (C6H12O6) and oxygen (O2) are reactants, whereas carbon dioxide (CO2), water (H2O) and energy are products.

How are Photosynthesis and Cellular Respiration Related?

In the information of each of these two processes, you must have noticed that the products of one process are reactants of another - and vice versa.
