Cellular Respiration
Aerobic Cellular Respiration is the process by which the cells in our body get energy to carry out their functions. Cellular respiration is necessary for all living things due to the fact that living things are made up of cells and all cells need energy to carry out their functions. It takes place in the mitochondria of mainly eukaryotic cells. Mitochondria are considered the powerhouses of cells due to their high folds of energy. During aerobic respiration, oxygen is always present, which means there is a large amount of energy present. During cellular respiration, the food we consume is broken down, from sugar molecules, to energy molecules known as ATP. ATP is thought to be the ‘energy currency’ of cells. ATP stores energy in a solid bond, and cells can utilize this energy by breaking that bond, subsequently eliminating a phosphate group and bringing about ADP, which can then be reconverted to ATP. Toward the end of anaerobic respiration, there are just two molecules of ATP produced. During Cellular Respiration, a maximum of 38 atoms of ATP are formed. There are three main stages involved in cellular respiration to get …show more content…

These electron chains are oxidised, transferring all of their electrons to their carrier molecules which are embedded in the ECT membrane. NADH enter the electron transport chain. The FADH2 originate in the citric acid cycle. In the first part of this process, electrons that pass from NADH to the electron transport chain, flow through the remaining complexes. NADH is oxidized to NAD during process. In the second part of this process, FADH is oxidized, picking up more electrons for the chain. In the third part of this process, there are no more electrons added to the chain. When these electrons arrive at the fourth part of this process, they are all transferred to a molecule of oxygen. Since the oxygen is gaining electrons, it is reduced to

The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.

    The ability to carry out metabolic processes, or the chemical activity that occurs in all living organisms, is essential to maintaining life. The total metabolism of an organism is made up of anabolic and catabolic pathways. Anabolic pathways expend energy to build important molecules. On the other hand, catabolic pathways release energy to break down important molecules. The energy found in in these pathways is from respiration.

    ATP (adenosine triphosphate) is made up of a nitrogenous base called adenine and three phosphate groups that are both attached to a ribose molecule. The three phosphates are all negatively charged, causing a repulsion between all the molecules- making ATP a loaded spring. When hydrolyzed, ATP loses an inorganic phosphate to create ADP (adenosine diphosphate). This makes the molecule more stable. Specific enzymes then help couple the energy and transfer a phosphate group from ATP to another molecule.

    Sirtuins (Sir2 proteins) are proteins that exhibit mono-ADP-ribosyltransferase, deacetylase, deacetylase, desuccinylase, demalonylase, demyristoylase, or depalmitoylase activity. They are involved in a broad range of cellular processes which include DNA repair, gene silencing, tumor suppression, life span regulation, apoptosis, inflammation, and stress resistance (low energy/calorie situations). (Michan, 2007) Mammals possess seven cellular regulatory sirtuins (SIRT1-7). SIRT1 partakes in metabolism inflammation in the nucleus and cytoplasm.

    In cellular respiration, your body uses glucose and oxygen in a process to make energy. The glucose is split in the cytoplasm of your cell, then its atoms go through a complex process which turns them into ATP, a useable energy source for your body. ATP can either be used, or stored in lipids for long term use. Lipids are one of the most diverse macromolecules because of the many functions they can perform. They make up a cell membrane, so without them, there would be no humans, they also can be used as a long term energy storage in the form of fat.

    ● Glycolysis can not proceed without a continual source of NAD+ to be reduced by the generation of electrons from splitting glucose. ● Without the small amount of ATP generated by glycolysis (2 net ATP) organisms would not have the ability to oxidize glucose which is the primary source of energy for most cells. ● In order to regenerate NAD+, pyruvate is reduced by NADH to form lactate (deprotonated lactic acid) and NAD+. This allows glycolysis to proceed.

    At the start of the race where the runner is at rest and before commencing running, energy in the form of adenosine triphosphate (ATP) is used to fuel metabolic reactions and functions. Muscle is mostly using fat at rest as an energy source, which is indicated on the great metabolic race graph that approximately 67% of fat and 33% of carbohydrates are used for energy consumption. Fats, which are also called triglycerides, are composed of three monomers of fatty acids attached to the three OH group of the glycerol. Additionally, it is a very good energy storage and stores more enegy than glycogen.

    In an organism 's body, chemical reactions are constantly taking place. These essential reactions can make or break the well-being of the body, yet the brain behind these changes is often times not recognized. This little brain or “macromolecule” is called an enzyme. An enzyme is a type protein that is able to speed up over 5,000 different reaction types an organism (2). Through catalyzation, the process of speeding up chemical reactions, enzymes attach to a substrate/molecule and break it down so that it can be used throughout the organism.

    The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

  • The Effect Of Exercise On Cellular Respiration

    Cellular respiration is when cells break down food and release energy along with oxygen and water. Oxygen is needed for glycolysis, the first stage of cellular respiration, to occur because if no oxygen is there, then fermentation takes place. With oxygen present, glycolysis continues to the krebs cycle which then carries high energy electrons to the electron transport chain through NADH and FADH2. After this process fully goes through the whole cycle, energy is released and cellular respiration has taken place. In this lab we test the effects that exercise has on cellular respiration.
