The reaction site of the first and second steps of aerobic respiration is called the matrix. Aerobic respiration occurs inside a Golgi body.
actually there are two types of cellular respiration:aerobic and anaerobic. aerobic cellular respiration only takes place when there is a presence of oxygen, while anaerobic or also called as fermentation takes place even w/out oxygen.

The second main part of cellular respiration is the Krebs cycle, also known as the citric acid cycle. This cycle takes place in the mitochondria of cells and involves a series of chemical reactions that ultimately result in the production of ATP, carbon dioxide, and high-energy electrons.
Respiration is one of the imperative functions of the body that are of crucial importance for all the living organisms be it human being, or the microscopic bacteria. In general the process of respiration serves two basic purposes in living organisms, the first one being disposal of electrons generated during catabolism and the second one being production of ATP. The respiration machinery is located in cell membranes of prokaryotes whereas it is placed in the inner membranes of mitochondria for eukaryotes. Respiration requires a terminal electron acceptor. Simply put, the respiration process, which uses oxygen as its terminal electron acceptor, is called aerobic respiration and the one, which uses terminal electron acceptors other than oxygen, is called anaerobic respiration.Differences between Aerobic and Anaerobic RespirationStarting from the bio-chemical pathway used to utilize bio-molecules, to the amount of energy produced in the respiration process, there exist a lot of differences between aerobic and anaerobic respiration. Let us discuss the two respiration processes separately with respect to the process, outcome and the chemical reactions involved in aerobic and anaerobic respiration.Aerobic RespirationAerobic respiration is the process that takes place in presence of oxygen. Aerobic respiration is the metabolic process that involves break down of fuel molecules to obtain bio-chemical energy and has oxygen as the terminal electron acceptor. Fuel molecules commonly used by cells in aerobic respiration are glucose, amino acids and fatty acids.. The process of obtaining energy in aerobic respiration can be represented in the following equation:Glucose + Oxygen →Energy + Carbon dioxide + WaterThe aerobic respiration is a high energy yielding process. During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized. Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules.Anaerobic respirationThe term anaerobic means without air and hence anaerobic respiration refers to the special type of respiration, which takes place without oxygen. Anaerobic respiration is the process of oxidation of molecules in the absence of oxygen, which results in production of energy in the form of ATP or adenosine tri-phosphate. Anaerobic respiration is synonymous with fermentation especially when the glycolytic pathway of energy production is functional in a particular cell. The process of anaerobic respiration for production of energy can occur in either of the ways represented below:Glucose (Broken down to) →Energy (ATP) + Ethanol + Carbon dioxide (CO2)Glucose (Broken down to) →Energy (ATP) + Lactic acidThe process of anaerobic respiration is relatively less energy yielding as compared to the aerobic respiration process. During the alcoholic fermentation or the anaerobic respiration (represented in the first equation) two molecules of ATP (energy) are produced. for every molecule of glucose used in the reaction. Similarly for the lactate fermentation (represented in the second equation) 2 molecules of ATP are produced for every molecule of glucose used. Thus anaerobic respiration breaks down one glucose molecule to obtain two units of the energy storing ATP molecules.
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
It means listen to your teacher :)
The second stage of aerobic respiration is the link reaction. This transition reaction forms acetyl coenzyme A. Glycolysis, the Krebs (or citric acid) cycle, and electron transport chain and chemiosmosis also happen at this stage.
the two main types of cellular respiration are aerobic cellular respiration and anaerobic cellular respiration.
During the second stage of aerobic respiration (Krebs cycle), two carbons are removed in the form of carbon dioxide at each turn of the cycle. This occurs during the conversion of isocitrate to alpha-ketoglutarate and then from alpha-ketoglutarate to succinyl-CoA.
actually there are two types of cellular respiration:aerobic and anaerobic. aerobic cellular respiration only takes place when there is a presence of oxygen, while anaerobic or also called as fermentation takes place even w/out oxygen.

Carbon dioxide is released in aerobic respiration during the second stage of reactions. Enzymes break down the pyruvate created during glycolysis (the first stage) into C02. The second stage is also called the Krebs Cycle
oxygen and glucose
During the preparation steps in the second stage of aerobic respiration (Krebs cycle), two carbons depart as carbon dioxide in the conversion of pyruvate to acetyl-CoA. In the cycle proper, all six carbons that entered are released as carbon dioxide molecules in the form of three molecules of CO2.
Carbon dioxide is produced during the Krebs cycle, which is the second stage of aerobic respiration that takes place in the mitochondria of cells. As part of this cycle, carbon dioxide is released as a byproduct when acetyl CoA is broken down to generate energy in the form of ATP.
Glycolysis, the first stage of aerobic respiration, occurs in a cell's cytoplasm. The second stage (acetyl-CoA formation and the Krebs cycle) and the third stage (electron transfer phosphorylation) occur inside a cell's mitochondria. They occur at the inner mitochondrial membrane, which is highly folded. Therefore, most of the reactions of aerobic cellular respiration occur inside the mitochondria of a cell.
