Respiration and Photosynthesis Cycle Photosynthesis and cellular respiration are connected through an important relationship. The relationship between photosynthesis and cellular respiration enables life to survive as we know it. The exchange of oxygen and carbon dioxide through photosynthesis or cellular respiration helps keep the atmospheric oxygen and carbon dioxide at a stable level worldwide. The equation for cellular respiration is, Cellular Respiration: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H2O.
The series of arrows indicates that there are many steps that are consisted in cellular respiration. The main function of cellular respiration is to generate ATP for the cellular to work. Cellular respiration transfers hydrogen atoms from glucose to oxygen which forms water. The transfer of hydrogen is the key as to why oxygen is so important to harvest energy from during cellular respiration.
Redox is when chemical reactions are transferred through electrons from one substance to another. When electrons are lost during redox it is called oxidation. The reason why electron transfers to release oxygen is because oxygen is an electron grabber. Oxygen atoms attract electron more strongly the many other kinds of atoms. When electrons and hydrogen moves from glucose to oxygen it moves as if they are falling because of the attraction of electrons to oxygen. Cellular respiration takes place in the mitochondrion, the glucose and oxygen reacts to produce carbon dioxide, water and energy, finally the chemical energy in within the glucose changes to chemical energy in ATP.
The term respiration is another word for breathing. Respiration on the organismal level should is not the same as cellular respirations even though they are very closely related. Cellular respirations require that a cell exchange two gases with its surrounding, the cell then takes in oxygen in the form of gas. It eliminates the waste in the form of gas carbon dioxide. In result, in the exchange of the gases between your blood and the outside that’s when air breathing occurs. Oxygen is now presenting air to your lungs and the carbon dioxide that is in your bloodstream diffuses into your lungs and then exits when you exhale. Cellular respiration is basically the living version of an internal combustion, the way that chemical energy harvest from food and then converted to ATP energy. Also, cellular respiration is an aerobic process, it requires oxygen.
Cellular respiration is the process of oxidizing food molecules, for instance glucose or carbon dioxide and water. Photosynthesis uses the energy from the sun’s light to power a chemical process that builds organic molecules. For example, plants, when plants go through the process of converting energy from the sun to the chemical energy of sugars and other organic molecules. Carbon dioxide is the chemical ingredient for photosynthesis, when gas passes from the air into plants and water; the water is absorbed from the soil in the plant’s roots. On the inside of leaf cells there are tiny little structures called chloroplasts. Chloroplast is the pigment that articipates directly in the light reaction, it absorbs mainly red light or a bluish violet. Chloroplasts use light energy to change the position of the atoms of the ingredients to produce sugars.
Sugar glucose is necessary for cellular respiration, during cellular respiration; the chemical energy in glucose molecule is converted to a form of plant that can be used for growth and reproduction. During the first stage of respiration, glycolysis, the glucose molecule is broken into smaller pyruvate and a little energy is released in the form of ATP. At this time the oxygen is not required so it is called anaerobic respiration.
On the second stage of cellular respiration the pyruvate molecules are combined then rearranged, then combined again
