1. Compare and contrast photosynthesis and cellular respiration.
The products of cellular respiration are the reactants of photosynthesis.
Cellular Respiration: Using Oxygen to Break Down Food for Energy
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).
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.
Photosynthesis and Cellular Respiration - SlideShare
Different kinds of food molecules enter cellular respiration at different points in the pathway. Cells break down simple sugars, such as glucose, in the first pathway — glycolysis. Cells use the second pathway, the Krebs cycle, for breaking down fatty acids and amino acids.
At the end of the entire process of cellular respiration, the energy transferred from glucose is stored in 36 to 38 molecules of ATP, which are available to be used for cellular work. (And boy do they get used quickly!)
How are photosynthesis and respiration related? | …
The reactants of cellular respiration are glucose (that is provided to animals by the plant-based foods we eat) and oxygen (breathed in from the environment through the respiratory system and carried to cells by the circulatory system), which react to produce the products carbon dioxide and water, which are exhaled back out into the environment. Energy is released by this chemical reaction, which is how cells get energy when mitochondria perform cellular respiration!
Photosynthesis and cellular respiration are two chemical reactions that happen inside of cells and are very important to living systems. They are both chemical reactions because in each process, matter is changed into new forms of matter. Photosynthesis occurs in the chloroplasts of plant cells (as well as algae and some bacteria). Cellular respiration occurs in the mitochondria of eukaryotic cells, both plant and animal.

How are photosynthesis and cellular respiration related?
Cellular respiration produces CO2 as a metabolic waste. This CO2 binds with water to form carbonic acid, helping to maintain the blood's . Since too much CO2 would lower the blood's pH too much, the removal of the excess CO2 must be accomplished on an ongoing basis.
Answer to How are photosynthesis and cellular respiration related?
The cyclical process of photosynthesis and cellular respiration are critical components of the survival of the Earth and the organisms that inhabit it.
How are photosynthesis and respiration related
The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. It can be in the presence of oxygen or . carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on where the are the site of most of the reactions. The energy currency of these cells is , and one way to view the outcome of cellular respiration is as a production process for ATP.
Photosynthesis and Cellular Respiration - Homework Set
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:
about a related process called cellular respiration
Cellular respiration is essential to the transfer of matter and energy through living systems. As living things use cellular respiration to transfer energy from food to ATP, some of the available energy in the food is transferred to the environment as heat, which travels through our atmosphere and goes back out to space. This energy transfer to heat occurs because cellular respiration isn’t 100 percent efficient at capturing the energy from food into ATP.
of the relationship between photosynthesis and cellular respiration.
After the large molecules in food are broken down into their smaller subunits during digestion, the small molecules can be further broken down to transfer their energy to ATP. During cellular respiration, enzymes slowly rearrange the atoms in food molecules. Each rearrangement produces a new molecule in the pathway and can also produce other useful molecules for the cell. Some reactions
