Extract of sample "Cellular Respiration"

 Fermentation is more than glycolysis in the sense that it allows glycolysis to continue using the products of fermentations. In other words, fermentation does not result in the making of ATP, but instead it allows the process of glycolysis to continue. Fermentation is also responsible for the removal of electrons from NADH molecules and thus recycling NAD+ molecules for the use in the glycolysis process.
In the human muscle during anaerobic respiration, glucose is broken down into two pyruvate molecules and is later converted to lactic acid.
Fermentation results in the production of carbon dioxide as a waste product and NAD that is responsible for the return process to glycolysis.
Section B
I. Approximately 30 to 34 ATP molecules produced via chemiosmosis
II. Oxidative phosphorylation takes place in an organelle known as the mitochondrion. It specifically occurs in the inner membrane of the mitochondrion matrix known as invagination membrane.
III. During the ETC protein complexes are pumped into the intermediary space
IV. Glycolysis depends on the continuous supply of carbon dioxide molecule
Answers to application problems
1. Interference of interruption of processes of cellular muscles can lead to twisting of muscles, muscle pulls and even cardiac arrest. Muscle pulls and cardiac arrest that be fatal if efforts are not made to restore the normal supply of oxygen that may be causing the muscle pull. Extreme cases of muscle pulls or cardiac arrest have resulted in death. As such, it is important to attend quickly to these sudden symptoms immediately they occur to avoid them turning fatal.
2. The oxygen that we inhale combines with the glucose at the cellular level through a process of oxidation of organic molecules in a process called aerobic respiration. Oxidation of oxygen and glucose results in the production of carbon dioxide exhaled, water, energy, and heat.
3. A running student must revert to walking when the rate of energy consumption is far much higher than the rate in which the student is breathing in. such student can maintain the running by inhaling and exhaling a little bit faster. If he or she does not, then she/he must revert to walking to reduce energy consumption. Read More

Cellular respiration and photosynthesis

...?Arbitrary relocation of molecules from the region of higher denseness to lower is known as diffusion. Osmosis is the phenomenon in which the water molecules' moves as per potential gradient across a semi permeable membrane (membrane which allows only particular molecules to go through it). Nutritions are transformed into operational energy by a biochemical process cellular respiration and electron transport. Electron transport is the procedure which pairs transfer in a midst NADH and O2 with the transfer of protons across a membrane. Due to electron transport phenomena, potential gradient is substantiated, which is used to derived adenosine triphosphate (ATP). Traversing of protons across the membrane of...

Aerobic Cellular Respiration in Isolated Mitochondria of Lima Bean Seeds

...? Investigating the Aerobic Cellular Respiration in Isolated Mitochondria of Lima bean (Phaseolus lunatus) seeds during the Conversion of Succinate to Fumarate in Krebs cycle Introduction: A basic concept in cellular respiration is the transfer of chemical energy (electrons) from an electron donor (i.e. carbohydrate, proteins and fat from food molecules) to an electron acceptor. Most of the organisms use oxygen as the final electron acceptor although some organisms (eg. Yeast) use other alternatives. During aerobic respiration, oxygen in the air is used as the final electron receptor which subsequently gets reduced to water. Energy is generated during this process in the form of a high energy molecule, adenosine triphosphate (ATP... ). This...

Cellular Respiration and Fermentation

...the energy from the pyruvic acid molecules was broken down at the Krebs cycle. Electron transport and oxidative phosphorylation involved the organization of a proton gradient across the NADH membrane generated at the Krebs cycle. ATP synthesis then took place through the ATP synthesis enzyme – in creating the phosporylation of ADP. The electrons were lastly moved to oxygen, where water was produced (Berg et al. 54). Conclusion Cellular respiration is an important process, as it is the process that leads to the formation of ethanol, which is an important ingredient in the manufacturing of alcohol. The process is also necessary in baking, as it allows for the raising of bread, through the generation of...

Cellular Respiration and Photosynthesis

...?Cellular Respiration and Photosynthesis- Important Concepts, Common Misconceptions, and Learning Activities: A Review One of the fundamental processes that sustain life is the process of capturing energy from the environment. Here on Earth, the main source of energy is the sun. Through photosynthesis, plants, animals and other photosynthetic organisms can capture the energy from the sun and store it inside their energy carriers. These carriers care the ATP (adenosine triphosphate) and sugars in the forms of chemical bonds. The release of oxygen into our environment and the chemical splitting of water results from the chemical reaction during photosynthesis. All organisms that are doing photosynthesis...

Cellular Respiration

...Cellular respiration After three steps during respiration, a molecule of glucose and 6 molecules of oxygen are converted to 6 molecules of carbon dioxide, water and energy (Rich, PR, 2003) as shown below. C6H12O6 + 6O2 ----- 6CO2 + 6H2O + 36 ATP However, the process of generating energy during cellular respiration is not as simple as the equation looks. Cellular respiration can be defined as a process of oxidizing fuel molecules such as glucose to carbon dioxide and water. The energy released during this process is held in the ATP molecules for all the energy consuming activities of the cell. The fuel molecules used by the cells include glucose, amino acids and fatty acids and the common electron acceptor or the oxidizing agent... more ATP...

Cellular Respiration and Fermentation

...of Paper: Cellular Respiration and Fermentation Jason Due 15 October Cellular Respiration and Fermentation Cellular respiration usually allows living organisms to use energy stored in the chemical bonds of glucose (C6H12O6). A cell always uses adenosine triphosphate (ATP) to supply their energy needs and so cellular respiration is a process in which energy in the glucose is transferred to ATP (Campebell 158). (al) During respiration glucose is oxidized releasing energy and oxygen is reduced to form water. The carbon atom of the sugar molecule is released as CO2. The complete breakdown...

Nacl and cellular respiration

... Why sodium chloride (NaCl) has no effect on cellular respiration Cellular respiration is the process by which food molecules like glucose are being oxidized to produce carbon dioxide and molecules of water. The energy released during the breakdown process is in the form of ATP, which is used in cellular activities. The process occurs in all organisms (Meldrum 22). C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 NaCl has no effect on the process of cellular respiration because of the following reasons; NaCl has no effect on temperature availability. Respiration rate is high in warm temperatures than in cold environment regardless of salt availability. This is because the effect of temperature is controlled by the activity of enzymes. Warm... from...
