What Is The Initial Site Of Respiration?

What is the definition of respiration?

the act of respiring; inhalation and exhalation of air; breathing.

Biology.

the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off..

What are 2 types of respiration?

There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic.

What is the correct order for respiration?

So, the correct answer is ‘Glycolysis, Krebs cycle, Electron transport chain’.

Which part of respiration produces the most ATP?

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

What are the 3 stages of anaerobic respiration?

Making ATP Without Oxygen The cells of most living things make ATP from glucose in the process of cellular respiration. This process occurs in three stages: glycolysis, the Krebs cycle, and electron transport. The latter two stages require oxygen, making cellular respiration anaerobic process.

Where does respiration take place in the body?

The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Energy is released in the reaction. The mitochondria , found in the cell cytoplasm, are where most respiration happens.

What are the stages of respiration?

The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).

What process in respiration happens first?

glycolysisThe first step of cellular respiration is called glycolysis. Glycolysis uses glucose to create ATP within the cytoplasm of the cell.

What is the correct order of cellular respiration quizlet?

The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs Cycle, and electron transport.

Where does the first stage of respiration take place?

The first stage of cellular respiration is glycolysis. It takes place in the cytosol of the cytoplasm.

What are the stages of respiration Class 10?

Steps of Respiration:Breaking down glucose into pyruvate: This step happens in the cytoplasm. Glucose molecule is broken down into pyruvic acid. … Fate of Pyruvic Acid: Further breaking down of pyruvic acid takes place in mitochondria and the molecules formed depend on the type of respiration in a particular organism.

Is Breathing exothermic reaction?

Respiration is another exothermic reaction. and this reaction releases energy. … If the temperature increases during a chemical reaction then that is an exothermic reaction.

What is the difference between respiration and breathing?

Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation. Respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.

What type of reaction is respiration?

Respiration is an exothermic process. During respiration, glucose molecules are converted into a number of other molecules which in the end give CO2 and H2O.

What are the 4 types of respiration?

BREATHING or ventilation. EXTERNAL RESPIRATION, which is the exchange of gases (oxygen and carbon dioxide) between inhaled air and the blood. INTERNAL RESPIRATION, which is the exchange of gases between the blood and tissue fluids. CELLULAR RESPIRATION.
