the relationship of cellular respiration and photosynthesis differences

ATP is produced in both processes. They are dependent on each other. All living things must either use photosynthesis or cellular respiration. Both produce. Read this comparison of photosynthesis and cellular respiration to find out how these necessary aspects of biology are related, and how they differ. Aerobic respiration produces energy whereas the photosynthesis is the process for trapping energy.

This process involves plants making food by using sunlight. In order to produce glucose, this process requires energy. This process occurs in some bacteria and in all plants. This process occurs within the chloroplasts, the chlorophyll-containing organelles inside a plant. In order to release oxygen back into the atmosphere and create sugar, this process requires water, sunlight, and carbon dioxide from the atmosphere.

This process converts the food created by photosynthesis into energy which is then utilized by living organisms and plants. This process creates energy ATP by using glucose.

All living organisms experience cellular respiration. This process occurs within the mitochondria, organelles with the ability to break down glucose. When combined with oxygen and sugars, energy in the form of ATP, water, and carbon dioxide are released as byproducts.

Similarities and Differences - Cellular Respiration and Photosynthesis

Retrieved on June 18, from Palomar College: Plants Photosynthesis occurs in the leaves of plants with little to none in the stems. Plant leaves are made of upper and lower epidermises, mesophyll, veins, and stomates. Mesophyll is the layer of the plant that contains chloroplasts and is the only place photosynthesis occurs. The energy taken is stored as ATP adenosine triphosphate.

What are the differences between aerobic respiration and photosynthesis in eukaryotic cells?

It is required for energy storage and is made of the nucleotide adenine with ribose sugar. Sciencing Video Vault Respiration The respiratory system allows living creatures that are not plants to obtain oxygen from the air for use in the blood and cells. Oxygen is a much needed nutrient and living organisms can roughly only survive for minutes without it.

Even if oxygen flow is reestablished, the damage can be irreparable. Alveoli are responsible for exchanging oxygen rich air with carbon dioxide rich blood cells. Unlike photosynthesis, it works day and night. Though it is not as simple reaction as we say, it is a long process which undergoes four major steps.

Glycolysis splitting or breaking of the sugar — It occurs in the cytoplasm of the cell, where one molecule of glucose C6H12O6 is broken into two molecules pyruvic acid. So here two ATP molecules are generated from the one molecule of glucose. Transition Reaction — Pyruvic acid is sent to the mitochondria, where it get converted into Acetyl CoA and get further broken down.

Even the carbon dioxide and water are released as a waste product from this reaction. In this reaction, thirty-two 32 ATP are generated for every glucose. So overall reaction is written as: However, above we discussed was about only aerobic cellular respiration, which occurs in the presence of oxygen and thus resulting in the production of thirty-eight 38 molecules of ATP from one glucose molecule.

But what about in the case when there is the shortage of oxygen like when we run or while performing any exercise. This is called anaerobic condition, where they produce only two 2 ATP molecules from one molecule of glucose from the glycolysis pathway only.

It does not undergo for further break down of the molecules, as the body demands immediate energy at that moment. Secondly, other reactions occur in the presence of oxygen, and this is the reason they are skipped. The anaerobic reaction is also called fermentation. Therefore, it is called as the catabolic process as energy is released in any form by breaking the large molecules into the smaller ones.

Differences between Respiration and Photosynthesis

But chemically it is an oxidation-reduction process oxidation is the removal of electrons and reduction is gaining of electrons by a molecule. This process occurs in light sunlight only and so-called as light-energized oxidation process. The photosynthesis occurs in leaves of the green plants, especially in the chloroplast which is the tiny structure present in cells of the leaves.

The chloroplast contains chlorophyll a green chemical is responsible for the green colour of the leaves. Further oxygen is released into the atmosphere from the leaves, and the carbon dioxide and hydrogen are used to generate food or glucose for plants.

It can be elaborated by the following equation: The removed hydrogen ions and electrons moved to the carbon dioxide CO2 and are reduced as the organic product. So overall reaction where carbohydrates C6H12O6 are formed during photosynthesis is defined in the equation. Though the above equation is a summary of the whole process, there is the involvement of many enzymes and other reactions too.

The process is divided into two stages:
