There are different ways it can end up in the ocean, for example, through rain fall or even rivers. When carbon dioxide enters water is it then referred to as carbonic acid. Being a weak acid does not seem very alarming compared to the very wide and very deep world ocean. However, humans’ impact on the Earth has increased the amount of carbon dioxide in the atmosphere which means there is an increase of carbonic acid in the ocean as well. Humans pump carbon dioxide into the atmosphere burn everyday by burning using excessive energy, fossil flue and even by simply breathing we are releasing more and more carbon dioxide.
Photosynthesis is performed by various life forms, however, the best organisms’ for this process is by cyanobacteria, algae and higher plants (Vermaas, 2013). The end result of the Photosynthesis process is the storage of energy in sugar bonds. Vegetation requires energy, H2O and CO2 in order to create sugar. Photosynthesis occurs in a plant’s chloroplasts, specifically using the green pigment that captures light energy; which is why it primarily takes place in the plant’s leaves. The veins in a leaf transport nutrients and water where they are needed and chloroplasts are in a plant’s mesophyll cells, which is where photosynthesis takes place.
Cellular respiration is the only metabolic process that could be utilized within heterotrophs; which are organisms who aren’t capable of making their own energy without consuming organic molecules. Photosynthesis on the other hand is carried out by autotrophs; which are organisms that could use the sun’s light energy to make their own organic molecules for energy. Photosynthesis is also the reverse reaction of Cellular respiration, where carbon dioxide goes through carbon fixation for glucose to be produced and water is oxidized in order to produce oxygen. In nature these processes work well under certain environmental conditions, and in this lab various pH levels were used to observe how they effected the production of oxygen in photosynthesis and the consumption of oxygen
Three important cycles in the biogeochemical cycle are the carbon, phosphorus, and nitrogen cycles. Each cycle has their own different roles in the ecosystem. One is in the air, one in the minerals of rocks, and the other one in the soil, and air. The Carbon cycle, which is carbon dioxide, is in the air, and is also used for photosynthesis. Humans, animals, and plants breathe in oxygen, and breathe out carbon dioxide.
Because these processes cannot be observed by the naked eye, it is difficult for many individuals to conceptualize. To fully appreciate this fundamental relationship, it is important to have an understanding of the living body as a chemical substance, to have basic knowledge about the chemical elements that compose the living body, and to appreciate that gas (CO2) is the source of the plant's body. These complementary systems allow for the existence of animals, which need the oxygen (O2) that is produced by the plants during photosynthesis. The relationship between cellular respiration and photosynthesis is continuous. During photosynthesis, glucose is produced from converted sunlight energy by plants.
Jessica Musser Human Impacts on the Carbon, Phosphorus and Nitrogen Cycles October 27, 2012 Professor Amanda Slaughter Environmental Science The carbon cycle is the set of biogeochemical processes by which carbon undergoes chemical reactions, changes form, and moves through different reservoirs on earth, including living organisms. The geological component of the carbon cycle is driven by plate tectonics and includes processes like volcanic eruptions and burial of carbon-rich sediments on the ocean floor. The biological component of the carbon cycle is driven by respiration and photosynthesis by living organisms. Humans affect the carbon cycle in many ways but mostly by burning fossil fuels (coal, oil, natural gas). The burning rate of these fossil fuels is close to 6 gigatons per year.
Cellular Respiration Autumn Truong October 15, 2013 5th Period Introduction Cited from the lab guide cellular respiration is the process of changing the chemical energy of organic molecules into a type that can be used by organisms. The equation for this process: C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy If enough oxygen is available, glucose may be oxidized and from looking at the equation above, if glucose is the energy source, then for every molecule of oxygen that is consumed, one molecule of carbon is produced. In simpler terms, carbon dioxide is formed as oxygen is used. The pressure, due to C02, might cancel out any change due to the consumption of oxygen. To fix this issue, the chemical potassium hydroxide will be added that will selectively take out C02.
Photosynthesis vs Respiration To obtain vital energy needed for life, organisms depend on the processes of both respiration and photosynthesis. The two processes share the same function of changing energy from one form to another, there are some similarities, but there are many differences between respiration and photosynthesis, such as the input and output molecules and cellular location. Photosynthesis is the process in which energy from sunlight is utilised to make the molecule glucose from water and carbon dioxide. Water is sourced from the surrounding soil, the carbon dioxide is diffuses into the leaf via the stoma. Light energy from the sun is converted into chemical energy in the form of glucose.
An investigation of the light-dependent electron transport using DCPIP Introduction Photosynthesis is a reduction-oxidation reaction, which uses carbon dioxide, water and light to produce water and sugar. During this reaction water is oxidised and carbon dioxide is reduced (Sadava et al. 2011). There are two parts to photosynthesis, the light-dependent reaction and light-independent reaction. The light-dependent reaction consists of changing light energy to chemical energy for the formation of ATP and NADPH.
The two combine initially to produce simple sugars and oxygen. As seen in the above equation, sunlight is the energy source, and the green pigment chlorophyll is the means whereby the sunlight can be used. In biochemical terms, the whole process is the reduction of carbon dioxide (to simple sugars) by hydrogen obtained from the breakdown of water mediated by chlorophyll. (The Plant World 2000) Chlorophyll is a green pigment which absorbs all wavelengths of light except green, as it reflects it to be detected by our eyes. It traps the light energy so that the process of photosynthesis can occur (May 2001).
