Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.”
One molecule of ATP is generated for each molecule of acetyl-CoA that enters the cycle. Electron carries that are generated into glycoses and energy from CAC that creates large quantities of ATP. Electrons are used to pass through the chain and move five protons across the mitochondrial membrane cell against the proton. This will result I a force to make the ATP. 14.
Step one involves two-carbon acetyl group CoA is added to the four-carbon oxaloacetate to create six-carbon citrate. Step two the citrate loses a particle of water and gains another one. The citric acid is converted to the enzyme aconitase. Step three the isocitrate loses another molecule of carbon dioxide and can be oxidized by forming the five-carbon alpha ketoglutarate. Step four the alpha ketoglutarate is changed to the four-carbon succinyl CoA. A particle of carbon dioxide is deleted and NAD+ is changed to NADH + H+ during the process.
While the ions are passing through the synthase, the group of phosphate bonds to an NADP molecule and then ATP forms. When the electron transport chains end, the NADP+ molecules will pick up the hydrogen ions and also the high-energy molecules which will form NADPH. After the NADPH molecules
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.
Cellular respiration is the process of creating ATP. There are three steps, glycolysis, citric acid cycle and electron transport chain. Not one step can occur without the other. Glycolysis is the anaerobic process of breaking down glucose into a useable form of energy. Within the cytosol of a cell a glucose molecule breaks down into 2 pyruvate molecules.
● Once oxygen is available, lactic acid is oxidized by NAD+ to recreate pyruvate which can then proceed through pyruvate oxidation to form acetate to enter into Krebs and NADH which can move to the ETC for a series of redox reactions to create ATP through oxidative
Cellular respiration is the process that allows organisms such as humans to use the energy in the form of ATP. It begins with glycolysis which is where glucose is broken down into two pyruvic acids. In this reaction 4ATP is made and NAD+ is made into NADH. However, it takes 2ATP to begin, so only 2 out of the 4ATP made is gained. Next, in the Krebs Cycle, the products of glycolysis are taken and made into another 2ATP.
Glucose provides energy for the cell. This occurs in the cytoplasm, produces two ATP, and does not require oxygen. Following glycosis next is the citric acid cycle. This stage occurs in the mitochondria, and produces two ATP and carbon dioxide. This step does not require oxygen.
The mitochondria is an organelle that is located in all eukaryotic cells. The mitochondria’s job is to convert glucose into adenosine triphosphate (ATP) by performing cellular respiration. The parts of the mitochondria are the matrix, mitochondrial ribosomes, cristae, mitochondrial DNA, the inner and outer membrane, the intermembrane space, and the ATP synthase. The matrix is located inside the inner membrane and contains the parts of the mitochondria inside of it.

Mitochondria are the main suppliers of ATP in most mammalian cells, it control both neurotic and the apoptosis signaling pathway, which is the apoptotic cell death pathways. Mitochondria is associated with the coordination of the cellular calcium (Ca2+) signaling. Mitochondria also produces and are targets of free radical species that control many characteristics of the cell’s physiology, this can be seen in Figure 1 and the structure and function can be seen in Figure 2. (Duchen and Szabadkai 2010) Currently, the theory that persists is that mitochondria is the progeny of aerobic bacteria that colonized a prokaryote (Spees, et al. 2006).
Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks. The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.
Ornthine is then carried back in the mitochondrial matrix and the cycle is complete. There are two nitrogens in urea. One nitrogen came from the ammonia produced in the mitochondrial matrix captured in the form of carbamoyl phosphate. The second nitrogen came from the α−amino group of the aspartate substrate in the reaction involving argininosuccinate synthetase. The carbon of the bicarbonate was the sole carbon of urea.
This occurs in both eukaryotic cells, as well as, prokaryotic cells. In the prokaryotic cells, it takes place in the cytoplasm; in the eukaryotic cells, it takes place in the mitochondria. Oxygen is vital for ATP production
