whats the relationship between PHOTOSYNTHESIS and CEllular respiration? | Yahoo Answers
Both plants and animals use this molecule to create energy, making it essential to life on Earth. When a plant carries out photosynthesis, it needs a source of carbon, hydrogen and oxygen to produce glucose, and it gets these elements from its surroundings. To create one molecule of glucose, the plant needs to absorb six molecules of carbon dioxide and six molecules of water. This leaves six oxygen atoms free, which are released as waste.
Carbon Dioxide Carbon dioxide accounts for 0. Carbon dioxide molecules, one of the building blocks of glucose, consist of one carbon atom and two oxygen atoms. When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air. Carbon dioxide doesn't have any hydrogen in it, though, so the plant must use another source for hydrogen.
The source that it uses is water. There is a lot of water on the earth, and every water molecule is composed of two hydrogen atoms and one oxygen atom. In order to take the hydrogen it needs to build glucose molecules, the plant uses the energy from the sun to break the water molecule apart, taking electrons and hydrogen from it and releasing the oxygen into the air. The electrons it takes are put into an electron transport system, where they are used to produce energy molecules called ATP that are used to build the glucose molecule-- all made possible by the sun's energy.
Thus, during photosynthesis a plant consumes water, carbon dioxide, and light energy, and produces glucose and oxygen. The sugar glucose is important because it is necessary for cellular respiration. During cellular respiration, the chemical energy in the glucose molecule is converted into a form that the plant can use for growth and reproduction. In the first step of respiration, called glycolysis, the glucose molecule is broken down into two smaller molecules called pyruvate, and a little energy is released in the form of ATP.
This step in respiration does not require any oxygen and is therefore called anaerobic respiration. In the second step of respiration, the pyruvate molecules are rearranged and combined and rearranged again in a cycle.
While the molecules are being rearranged in this cycle, carbon dioxide is produced, and electrons are pulled off and passed into an electron transport system which, just as in photosynthesis, generates a lot of ATP for the plant to use for growth and reproduction.
This last step requires oxygen, and therefore is called aerobic respiration.
Photosynthesis and Respiration
Thus, the final result of cellular respiration is that the plant consumes glucose and oxygen and produces carbon dioxide, water, and ATP energy molecules. At first, this doesn't seem to make any sense! If the plant can use the energy from the sun to make ATP, why does it go through all the trouble of then using up the ATP to make glucose, just so it can get ATP again?
There are two reasons why the plant does this.
First, in addition to ATP, the plant needs materials to grow. Glucose is an important building block that is necessary to produce all of the proteins, DNA, cells, tissues, etc.
Second, one problem with the sun is that it goes away every night, and during winter it isn't very bright. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes.
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.Relationship between Photosynthesis and Cellular Respiration
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.
