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 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.

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.

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.

The chemical energy in covalent bonds (C-C and C-H) of glucose are released and converted. The majority of the metabolic pathways are parallel to all organisms. Eukaryotes have many classified metabolic pathways with reactions ensuing inside particular organelles and synchronized by crucial enzymes, these enzymatic activities are either activated or inhibited. The energy currency of cells is known as ATP.

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.

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.

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.

Introduction: Respiration encompasses cellular respiration and external respiration. In cellular respiration the vast majority of energy that most living organisms need are satisfied by the mitochondria. The main driving force behind the mitochondria producing the high yield of ATP would be due to oxygen gas. For external respiration, encompasses breathing, gas exchange in the alveoli, transportation of gases through the blood, the delivery of gases to the systemic tissues, and the gas exchange at the systemic capillaries.

4. use a specific example in your discussion. How does cell utilize energy? Cell utilize energy during the different processes of growth, respiration, excretion ,nutrition, reproduction Metabolism etc, this energy utilization is prompted via the transfer of electrons which results in the increase in potential energy or decrease in the potential energy during the building up of monomers through bonding into macromolecules or the breaking down of macromolecules into monomers .

They harness energy by breaking down food molecules to make adenosine triphosphate or ATP, which is the main carrier of energy in cells. The inner membrane is thrown into folds called cristae which provide more surface area for greater cellular respiratory productivity. The matrix is filled with a semifluid medium containing enzymes that break down carbohydrate products. Ribosomes are the sites of protein synthesis.
