P6 – Respiration comes with two variations, one being aerobic respiration and the other being anaerobic respiration. Generally speaking respiration is the process in which energy gets released to be used by cells which comes from glucose. This process can occur with the use of oxygen which is named with one of the variations of respiration called aerobic respiration. Respiration that does not require oxygen is called anaerobic respiration.
Equation for aerobic respiration = glucose + oxygen Carbon dioxide + water (+ energy)
Co2 + H2o are waste products in this chemical equation whereas the glucose + oxygen are the substances that get used up.
These reactions occur within the mitochondria the majority of the time within both animal and plant cells. The variable that controls respiration are the protein enzymes
Aerobic respiration involves proteins like enzymes to assist with the process of breaking down food molecules in order to be

ATP is a form of energy in which is produced through aerobic respiration which uses oxygen. As a result of this process products such as H20 and CO2 are produced, without the presence of oxygen the cells would not be able to produce energy although this is where anaerobic respiration comes in to assist with the production of energy for cells.
As the process of aerobic respiration takes place Oxygen is reacted with the glucose which forms CO2 + H20 + ATP. The chemical equation for this is > C6H12O6 + 6O2 → 6CO2 + 6H2O + 2900 KJ (ATP)
The lack of oxygen during the process of anaerobic respiration causes a breakdown of glucose by cells which get broken down into lactic acid + ATP. This stage causes a release of energy although it is not as high in quantity in comparison to aerobic respiration. The chemical equation for this is > C6H12O6 → 2 C3H6O3 + Energy
gars. These are then split into two three-carbon sugar phosphates and then these are split into two pyruvate molecules. This results in four molecules of ATP being released. Therefore this process of respiration in cells makes more energy available for the cell to use by providing an initial two molecules of ATP.
Cellular respiration is a chemical reaction used to create energy for all cells. The chemical formula for cellular respiration is glucose(sugar)+Oxygen=Carbon Dioxide+Water+ATP(energy) or C6H12+6O2=6CO2+6H2O+ energy. So what it is is sugar and
I should read the article more carefully. I answered O2 has nothing to do with cellular respiration and it is wrong. According to the article, page 5, O2 said cellular respiration requires both myself (O2) and glucose by facilitated diffusion. The correct answer is oxygen and glucose work together to produce ATP. ATP molecules are yield during cellular respiration.
Both starch and sucrose can be converted back into glucose and used in respiration. Photosynthesis happens in the mesophyll cell of leaves. There are two kinds of mesophyll cells - palisade mesophyll and spongy mesophyll. The mesophyll cells contain tiny bodies called chloroplasts which contain a green chemical called chlorophyll.
Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.
That is when muscles switch from aerobic respiration to lactic acid fermentation. Lactic acid fermentation is the process by which muscle cells deal with pyruvate during anaerobic respiration. Lactic acid fermentation is similar to glycolysis minus a specific step called the citric acid cycle. In lactic acid fermentation, the pyruvic acid from glycolysis is reduced to lactic acid by NADH, which is oxidized to NAD+. Lactic acid fermentation allows glycolysis to continue by ensuring that NADH is returned to its oxidized state (NAD+). When glycolysis is complete, two pyruvate molecules are left. Normally, those pyruvates would be changed and would enter the mitochondrion. Once in the mitochondrion, aerobic respiration would break them down further, releasing more
Overview of Cellular Respiration and Photosynthesis Written by Cheril Tague South University Online Cellular Respiration and Photosynthesis are both cellular processes in which organisms use energy. However, photosynthesis converts the light obtained from the sun and turns it into a chemical energy of sugar and oxygen. Cellular respiration is a biochemical process in which the energy is obtained from chemical bonds from food. They both seem the same since they are essential to life, but they are very different processes and not all living things use both to survive ("Difference Between Photosynthesis and Cellular Respiration", 2017). In this paper I will go over the different processes for photosynthesis and the processes for cellular respiration and how they are like each other and how they are essential to our everyday life.
...s in the cells within humans (multicellular organisms) switching from aerobic respiration to anaerobic respiration. This causes less energy to be produced per molecule of glucose (Baskin, S. I. et al. 2014), (“Environmental”. N.D.) (Allison, L. A. et al. 2014). The less produced energy causes cells to die from lack of energy, and once enough cells die, the multicellular organisms (humans) die.
= = = [IMAGE][IMAGE]6CO2 + 6h20 light energy and chlorophyll C6H1206 + 6O2 Carbon dioxide + water converted into glucose and oxygen. Theory of photosynthesis Photosynthesis is a chemical reaction, which uses the energy from sunlight to convert carbon dioxide and water to oxygen.
If cells are denied energy, they will die. The second law of thermal dynamics says energy is lost in the form of heat whenever energy changes form. ATP is stored in the c. Glucose produced by C02, water and ATP. Respiration may be said to be a controlled breakdown of glucose that produces ATP for cell activities to be carried out. The purpose of the lab was to show the effect of temperature on the rate of respiration.
Aerobic requires oxygen and takes place inside the mitochondria of iving cells. The energy is stored as adenosine triphosphate (ATP) Aerobic respiration produces 2890KJ/Mole or 38ATP. This is much more than anaerobic. The
According to our text, Campbell Essential Biology with Physiology, 2010, pg. 78. 94. Cellular respiration is stated as “The aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis”.
Fermentation is an anaerobic process in which fuel molecules are broken down to create pyruvate and ATP molecules (Alberts, 1998). Both pyruvate and ATP are major energy sources used by the cell to do a variety of things. For example, ATP is used in cell division to divide the chromosomes (Alberts, 1998).
C6H12O6 + 2 ADP + 4 H+ → 2 C2H5OH + 2 CO2 + 2 ATP + 2 H2O
When humans consume plants, the carbohydrates, lipids, and proteins are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic and aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration converts the material into a useable energy called ATP. ATP is the energy form that cells can use to perform their various functions, and it can also be stored for later use.
